    FCM Move - Summer Special - Crucial Ride Harmony Concepts - Miata For Sale

    Greetings once again, M3 forum friends!
    Click image for larger version  Name:	EFRRyTfU4AAuGz7.jpg Views:	0 Size:	20.3 KB ID:	313214






    I do indeed feel like Gandalf who fought the Balrog and while victorious, also expired. Yet, it was not his time and he was sent back.

    I nearly died July 5th, 2025. Through God's Grace and the wonderful intervention of the medical staff around me, I've been given a second chance - and I intend to make the most of my life moving forward. The past three weeks have been some of the most productive I've had since before covid beset all of us.

    The details of what happened to me are not relevant to post here (if you're curious, I can share more via phone if / when you decide to engage with my Summer Special offer / at some later date). What matters is the clarity and direction I feel now. FCM is finally moving out of the Bay Area (where the cost of living and opportunities are no longer optimal) to Birmingham, AL.

    I'm offering a Summer Special to give a nice boost to those who want to Join the Elite: pay for an FCM Elite Stage 2 ($2800) and get upgraded to the FCM Elite Stage 3 Ultimate ($5000 value and really worth more since it's superior to anything MCS / Ohlins / etc. have to offer).

    Please watch this video and feel free to email (don't PM me here unless you're international: call or text my cell: 408-221-8247). To some extent, time is of the essence as I have to decide in the next week whether I take my mill and lathe, or leave one or both behind, along with other essential equipment which I must ship such as the shock dyno and shock assembly machine. After 15 years in one location, I've acquired a good bit of 'stuff' and am slowly but surely doing triage on what needs to come and what doesn't.




    UPDATE: 8/3/2025 - Due to factors I have no control over, my move date has been pushed out about 1.5-2 months. I'm honestly relieved as I can finish existing work, meet with more local BMW owners (like tlow98 and heinzboehmer, and just pace myself. Might even do another / final track day at Laguna or Sonoma or Thunderhill before I head East.

    I still appreciate your willingness to take advantage of the Stage 2 -> Stage 3 Ultimate offer and put at least a 25% deposit ($700) to help build up savings and pay my exorbitant SF Bay Area rent another month or two! Thankfully, my customer 'Farkle' (Drew) after driving Christina decided to upgrade his F31 wagon from Stage 3 to Stage 3 Ultimate so now I've paid August rent on time - WOOT WOOT!

    I've had a couple people already make partial deposits and my intention is to engage in those builds PRIOR to leaving for Birmingham. No hard ship dates, but it's certainly possible and because I know our E46 platform so well, the process is more efficient than on a brand-new vehicle (like a Saab 9-3 which someone is expressing interest in having me work on...).

    I'm also selling our Fat Cat Motorsports prior flagship / demo car, 'Senna', a 1995 Miata M-Edition with ABS (rare and valuable!), Blackbird Fabworx 12-pt street cage, FCM Elite Stage 3 suspension (450/375, very streetable and still good for performance), lots of detail work to bump steer correction, ISC upper offset control arm bushings for up to -4.5 deg front camber, fenders rolled and tubbed (rear) to fit 275 Hoosiers (grip monster!). The dual-element rear wing from Ciro Design Racing is now included in the $7400 price.

    Senna was designed to be a streetable track car as I didn't have a tow vehicle and also wanted to enjoy him on the street. He has a catalytic converter and was intended to pass CA emissions while being nearly a fully-prepped track car). Asking $7400 firm. There are several PDFs on the website (linked in the CL ad) indicating all the work that's been done to him and how special he is as a track / autocross car.

    UPDATE on Senna: I've got him at Edge Motorworks and aiming to get him road-worthy so I can sell a runner instead of a 'bring a trailer.' Might turn out I won't want to sell him when he is running again, but if you or someone you know are interested, send them my way. If I can't sell him, I'll take him to 'Bama with me and turn him into a TTOD contender as before

    ===

    Now, to the technical aspects of my share. End of last year, I felt a strong prompting to create a series of videos that could be largely 'standalone' to explain what a factory suspension is probably doing, compare and contrast to the typical aftermarket suspension, and then indicate how the FCM approach using Ride Harmony and Race Synergy are able to get superior results. I used some Porsche Boxster components to help illustrate just how close most front bump stops are to engaging, and how HUGELY that interaction affects the car's ride frequencies and handling balance.

    Getting Ride Harmony is not 'magic' but you do need to understand what to change and why, in the correct order. By utilizing the correct principles applied at the optimal point in the design process we can achieve a smooth ride settling response (via Flat Ride or 'Fast Settling' as I also like to call it) along with a natural, fluid 'rear-driven' handling response (where a rear-wheel drive or all-wheel-drive car actually WANTS to rotate from the rear wheels!).



    I would strongly recommend you watch the first 3 videos, taking whatever time you need*. I promise you will learn something new, even if you're already familiar with my work.

    The end result of understanding the Crucial Ride Harmony series is to provide you with necessary questions to 'Qualify Your Vendor' (a 2-video series). Once you know what the factory intended, and have a sense of how the aftermarket may differ from factory, then based on your goals you can ask some very pointed questions of a vendor to determine whether they deserve your business or if you should:

    I've had numerous conversations with customers going over these various Crucial Ride Harmony concepts and as much as I enjoy the conversations, I get tired of repeating myself So I made the videos with a classroom-setting mindset including props and visuals which I find superior to just having a phone chat. I am happy to engage and answer basic questions, but if you need more information about my methods, I'm going to refer you to the Crucial Ride Harmony series or I will charge you $300 / hour (my current consulting rate). It's your choice! All those who take part in the Summer Special get the 30 min ($150) consult for free so you only need to pay the Stage 2 price ($2800) plus shipping / handling / insurance to get the dampers back to you. Some assembly required, we'll go over the full parts list based on what you have and what you need to buy. That would include items like camber / caster plates, a bigger front bar of some type (I prefer the GC Race bar), rear weight jacker, and then the springs themselves.

    Thanks for reading, and I'm eager to see what comes of this offer and your interest in Joining the Elite with a very special promotion at a transformative time in my personal and business life!

    Since it's been a while since Shaikh posted, I feel like newer members need some background as to who he is.

    Shaikh is the owner of Fat Cat Motorsports. He is largely responsible for the flat ride concept in aftermarket suspensions, as well as for creating this for the e46: https://www.fatcatmotorsports.com/FC..._M3_Online.htm
    Perhaps more important to many, he's been responsible for setting up many winning race Miatas/BMWs.

    For me personally, the two above items have been completely transformative to everything about how I view suspensions. Flat ride is a transformational concept for aftermarket suspensions (not sure why, since literally every car from prius to F150 to GT3RS has it stock), and that spreadsheet allowed me, for the first time, to really have a good understanding of what the changes being made are actually doing.

    In terms of product, what FCM offers is also unlike anything else on the market. He helps apply the flat ride concept, your specific use case for the car, and your corner weights to select spring rates (per corner, or per axle) for your car. He then custom valves the shocks (Bilsteins) per corner to match your spring rates and corner weights, as well as adding the "Ripple Reducer" (bypass holes that eliminate a lot of the "noise" that normally gets translated. He also works in proper bump stop tuning. Optionally (stage 3), he adds a blowoff valve that has the same concept as a Ohlin's DFV/Penske F1 valves-- hit a large curb and the high speed compression is blow off/bypasses the shock.

    I've had a lot of suspensions over the years-- TCKs, Ohlins, JRZs, Motons, KWV3s, Koni yellows with eibachs. 6 years into running my FCM Stage 3 setup, I have no desire to change again. The only setup that I liked ever close to as much was the Ohlins after (with great effort and expense) I changed them to be flat ride.

    Currently working up to a FCM setup for my e82 128i, which IMO basically requires someone like FCM-- because also the aftermarket options are tailors around the 300 lb heavier 135i and are, are per usual with the aftermarket, not flat ride.

    Anyway, would recommend. If you end up going down this road, set a couple hours aside for the the phone conversation. Ideally go in with your corner weights (doesn't need to be corner balanced, as the spread sheet can calculate what your corner balanced weights will be given any starting point).


    My car rides better than stock, handles better than stock, grips better than stock, and the only adjustment I have to deal with at the track is camber-- which is an amazing reduction in cognitive load and busy work. When your shocks are valved for your spring rates and corner weights, any deviation from optimal is a reduction in grip, control, and ride quality.

        Yes!

        I had the pleasure of driving Shaihk’s 330i sedan with his suspension last week in comparison to my M3 swapped 330i sedan. I’m shopping for a potential replacement for a couple cars. After having several setups in e46 M3s (ground control full coilovers, stock springs + bilstein b6, stock spring + Koni) I’m after comfort plus capability, aka grip. Because anything else is a compromise.

        Shaihk’s car has:
        350lb-in front linear springs
        650/700-in rear linear springs
        His Full shock package (dampers, bump stops, etc.) he builds for our e46 chassis
        - Bf Goodrich 200tw tires - forget the exact type
        - aftermarket sways (dunno which type?)

        My car:
        Stock m3 front progressive springs - 155lb/in
        Stock m3 front progressive springs - 380lb/in
        Koni yellow sport dampers front and rear.
        - front 1/2 turn off full soft.
        - rear 1/2 turn off full soft.
        Firestone Indy 500 burner tires (350 tread wear from memory)
        Stock M3 swaybar

        I say all this to say that I’m upset my car rides worse on the street than Shaihk’s. Both grip and comfort mine is worse. He has more than double the spring rate (linear, even!), stiffer sidewalls, and more sway bar. The grip level I understand - those tires, I can’t match them.

        I drove it on the worst road near me. It’s right next to the garbage dump, lol. The dump trucks have torn it up. In some areas whole slabs are missing with 2” hard edged potholes. The entire road is covered in patch-fills that are all crescent shaped in profile. It’s asphalt but it actually resembles riding off-road.

        My car can remain reasonably composed up to about 25mph, but you bounce around in your seat quite a bit. Anything beyond that and it bangs the bump stops and you feel bad so you slow down. I went 50mph- ish in his car and it felt controlled and polished. I could hear the tire impacts, but remarkably smooth in-car experience.

        A couple other things I haven’t experienced is the mid corner bump absorption and brake feel/control at the limit. While cornering the chassis stays composed, doesn’t skip, skid, or need to be corrected the way my car does when hitting asphalt heaves or pot holes. I was being kind of dick when I asked if I could limit brake test in the bumps, haha, bc yeah, it’s a torture test. Stopped smooth while maxing the shock travel in some areas. The ABS was pumping away. I needed less steering correction than in my car, as well.

        Anyway, that’s my experience on crap roads and clover leaf on-ramps. Shopping around I don’t really know what to compare it to. No one else is really doing this level of product. Not that I know of?

          Thanks for sharing your impressions, tlow98. I am still envious of your 'M3 sedan' sound and pull! To clarify, my front springs are (IIRC) 375 lb/in left, 350 lb/in right, rear springs are 700 lb/in left and 650 lb/in right. Approximate ride frequencies of 1.9 / 2.0 Hz. I'm even thinking of dropping the front spring a touch more to further increase the Flat Ride behavior but she's working real well and it's a good basis of comparison for other E46's (M or non-M) to go same / softer / stiffer.

          The fact that you know the same 101 / Holly / Shoreway (garbage facility) roads so well really made this an awesome comparison.

            I was there as well and got a chance to drive the car around.

            Right road compliance is absolutely insane. Shaik's car is WAY more comfortable than mine. Seems like it's more comfortable than my 128i daily. I was very blown away by this

            The car is also very grippy, but like tlow98 mentioned, it was on 200tw tires, so kinda hard to objectively compare against.

            Hard to beat the value that fat cat offers though. Roughly the same price as most aftermarket suspension, but you get something tailor made for your car.

              Can highly recommend 350/325 700/650 as a great pairing with the FCM stage 3 shocks 😁

              I'm possibly working up to a FCM setup for our 128i. Every setup that fits that car is a hand me down 135i setup (350 lb heavier car), which is generally a maybe slightly tweaked maybe unchanged e90 (or, worse, e90 M3) setup-- designed around an even heavier car. Nothing is remotely optimized for the 128i, much less my slightly lower riding M sport variant.

              After experiencing the comfort of a track capable setup (my M3's setup is basically the same as Shaikh's, just with 25 lb softer springs up front), I'm quite curious what a street only setup would be like. Lexus, but with handling and body control?​

                  You still have to provide the Bilstein dampers, springs, mounts, etc. I think he provides the bump stops, consultation time, and the rebuild.

                  Along these lines...is everyone using the non-adjustable H&R coilovers from ECS?

                        Good question. You're paying $2800 for me to optimize the H&R Street Performance coil-overs, p/n 50415 you'd have shipped to me (either new or very lightly-used). For now, you're paying for FCM Elite Stage 2 to get FCM Stage 3 Ultimate - at least until I end the deal, likely mid-September. The springs are unfortunately useless for anyone who cares about suspension travel or Flat Ride so I recycle those and we'll select new springs based on your driving needs and corner weights (Racer's Edge part of the E46 M3 Ride Harmonizer spreadsheet!).

                        I decided years ago that - in the dark - every damper looks about the same. So I couldn't justify charging a Porsche or BMW customer 3x what I'd charge a Miata customer for what amounts to the same work in optimizing the damper behavior. This generally makes Miata customers say things like 'but but it costs more than I paid for my car!!' and Porsche customers are 'ok, that's very reasonable especially compared to blah blah.' Most BMW owners I speak with are somewhere in-between, depending on what you paid for your car, how much you've spent on other items, whether you're aiming to race / HPDE / etc.

                        I want to ensure that by paying a lower price people do NOT think they're getting a lower-Quality product. I am convinced a lot of the prices being charged are just price gouging (no names specifically mentioned but you can guess). I've seen multiple dyno graphs that area nearly identical of the 3-letter popular controlling motion dampers across platforms that OUGHT TO BE very difficult, due to geometry / weight / spring rates. When you start peeking behind the curtain, you might not like what you see...

                        The $2800 is what you'd pay me to do the damper tuning (compression / rebound / modifications & hardware for Ripple Reducer and Ultimate). The cost of top mounts and springs are extra. I provide a softer front internal bump stop than H&R gives (I get it from Bilstein) and the rear bump stop (`60mm medium, or ~200 lb/in) is provided by H&R and is ok but I would recommend switching to the Speedthane 58mm red which is softer (~100 lb/in) and more progressive. It's available through various sources, but if you buy from 5XRacing.com I get a 10% commission on their sales since they're my wholesale dealer on bump stop products. I have a limited quantity in stock and won't be ordering more until I move so about the next 4-5 people will get rear bump stops included as well as the softer / shorter Bilstein front stops (always included).



                        I'll advise you on appropriate sway bar(s) { usually just a larger front bar than stock } and then the spherical rear weight jacker from Ground Control is what I suggest (Rogue makes a knock-off to my understanding).

                        Note that to service a damper is typically about an hour's work which is my consult / labor rate of $300 / hour. The initial high cost is to get all the technology and interaction with me to dial things in. In the rare event that a repair is needed (and it is very rare), it's 1 hour per damper plus likely a new rod guide (~$40). New AMSoil 5wt Shock Therapy oil is included.

                          Not dumb at all - yes, they are usually designed for 60mm on the BMWs. Porsches can use 60mm or 70mm but BMW seems consistently 60mm.

                          The H&R front strut housing is designed for a 60mm spring perch. There's enough aluminum present to turn the front spring perches to fit 2.25 inch ID springs (57.3mm) which I've done for numerous customers. I do that here on my Clausing lathe.

                          The H&R rear height adjuster is set for 60mm but I really recommend an articulating spring perch which then you can use 2.25, 2.5, or 60mm if you want (I think). I prefer 2.5 inch to get the most spring travel in the rear suspension and avoid coil-bind. The weight savings in the rear of 2.25 vs. 2.5 inch ID is pretty minimal.

                          Up front where tire / wheel clearance is more of a concern I get going with 2.25 inch ID springs. Of note, on my E46 330i with non-M suspension components, I'm using 2.5 inch (63.5mm) springs on Bilstein PSS (I made a ring to space outward from 60mm to 63.5mm). I use a 10mm spacer to fit 285s BF Goodrich R1 or a standard 5mm spacer to fit my usual 255s Rival S.

                          Oh, and the H&Rs comes with a front and I'm pretty sure also rear dust boot. The front dust boots measure just under 57mm so should also barely fit a 2.25 inch spring.

                            Don't remember exactly why, but I think I'm running an Ohlin's spring perch for a specific spring I wanted.

                              I see Hoosier, I salivate

                              Hmm.. my current Lotus Exige customer reported some unusual spring perch measurements. Could be the spring ID 65mm, so their specific perch located the spring better with less slop?
