Anyone tried JRZ RS Pro coilovers?

EthanolTurbo ... OP how are the Koni Yellows holding up? lol

while MCS' reputation is fairly new.

I know ..old thread.
Just to mention for those who don’t know
Jerome Van Gool one of the MCS founders was one of founders of JRZ…left …started Moton and then MCS. So I think MCS has an awesome reputation.

Keep in mind MCS and JRZs are sold as just the dampers, with everything else being an added option on top of that (springs, helper springs, camber plates, end-links, RSMs, etc) you probably have to add another $1k on top of that. Based on my research when I was looking at these options Ohlins are for street first but can handle track use with some limitations, whereas MCS/ JRZs are track first without beating you up on the street. At the end of the day the spring rates you select will have a big impact on comfort and street manners

Good point.

You will need
Rear articulating perches (I have GC)
Adjustable Endlinks (Bimmerworld is fine)
Rear Shock Mounts w/ Reinforcement (I use Vorshlag)
Thrust sheets or nicer equivalent
BMW Front Shock Tower Reinforcement Plates
Camber Plates (I use Vorshlag)
Helper Spring (if desired)
Helper Spring Perch (if desired)
Rear spring perches
Springs

I am sure I am missing something. I know that MCS allows for street or track valving setups. I run the heavy Spec E46 spring setup and the ride is better than stock when adjusted.

the MCS seems to be roughly at the same price point as the TCK DAs, curious what peoples thoughts are on street manners of the MCS/JRZ as TCK has the reputation as being the best street setup. this price point is competing with the much loved Ohlins also.

I'm in the market for a new setup come BF sales this year.

Did they say why they preferred MCS over JRZ?

Yea, so I was walking around the shop and they had a Cayman and a 911 (996 I think) that haD JRZ’s that were leaking, which could have been pure happenstance. They also run MCS on their rentals and have never had any issues. The owner has an E92 he has sunk hundreds of grand into and he runs the three way remote MCS. It was a preference issue, not a knock on JRZ’s. Hell, I had JRZ’s “in my cart” until I was puttering around on Bimmerworld annoying the chat guy. I also live closer to the MCS factory so I can toss them in the mail if I want them serviced and have them back relatively quickly. JRZ’s are top notch, but for my money MCS has vastly exceeded my expectations. I hope that makes sense.

Thank you for the replies and info everyone. I think I'm going to end up going with MCS 2 ways instead.

Just curious, why did you choose MCS vs. JRZs? Biggest difference between the two would be that the JRZs have external reservoirs, while the MCS 2WNRs of course don't. Both are amazing...and there are people out there that swear by both brands. I personally think the RS Pros may perform slightly better than the 2WNRs because of the external reservoirs, but who knows. JRZ also has an incredibly lengthy history in motorsports--building dampers for select McLaren F1 GTRs, Formula 3, DTM, etc.. while MCS' reputation is fairly new.

I don't have too much experience with coilovers on the E46 platform, but I had JRZ RS Pros on my E90 M3, and they blew every other setup I've had out of the water .. including two sets of KW Clubsports. They rode fantastically with 650/800 spring rates, and overall transformed the driving experience of the car (to be expected.) Grip was massively improved, and steering responsiveness seemed to be improved as well. Bump reaction doesn't really change with the individual damper themselves, but more so has to do with suspension geometry, and how much the car was lowered.

I was torn between JRZ and MCS for a while before finally committing to MCS 2WNR. I had a long talk with the guys who run the shop outside VIR before choosing MCS. They like the JRZ's but always recommend the MCS. I know this is anecdotal but they have been nothing less than incredible. I run about 20 track days a year as well, and the car is almost exclusively a track car. I drive around 100 miles outside the track a year. I purchased a setup through Bimmerworld and am extremely pleased with the result. Best modification I have made to the car hands down. No spacers needed in the front for the wheel and tire setup above. All that being said, you cannot go wrong with JRZ.

What size wheels and tires are you going to run? I have a set and run 18x10 +25 wheels with 275 35 size tires. I have to run a 3mm spacer up front. Just giving you a heads up.

I have JRZ 2-way non-remotes and so far they have been the best mod on the car. They’re right at home on track, soaking up bumps/ kerbs really well and predictable. I’m on stock sway bars with 650/750 spring rates and have no need to upgrade sways in order to improve turn-in, responsiveness so pretty happy on that front. On street I just turn compression/ rebound on the front almost all the way down and it becomes a very live-able suspension without being thrown around at every single bump/ imperfection. Tons of grip with fast 200tw tires or 100tw. I used to run a052s and that setup was awesome, have since switched to some cheap-ass Federals and they suck b@lls lol

+1 hear on this quote.....the best suspension I’ve ever had! Transformed my car the KW3 I had were good but these are on another level!

[Daniel]

You can’t go wrong with those IMO.

one key thing I always look for when choosing suspension whether it be for my motorcycle or cars is local support. Find a reputable track oriented shop/shops near your area and see what they prefer for your platform. The support for setup around your local tracks will be way better than forum feedback.

Interested in the statement that BMW Motorsport has been rebranding JRZs for years... I believed it was actually KWs they used... found vindication in the fact the M4 GTS has recently been specc'd with KW Clubsports from factory.

I should have specified that the late 90s and early 00s BMW E36 and E46 race cars ran JRZ. I know the more recent M6/M8 race cars use Ohlins. I didn’t hear great things about the KWs on the M4 GTS but hopefully they can turn it around with this new M4 GT3.

[STAATS]

I’m planning on buying a set of JRZ pro 2-ways in the future. I kept going back and forth trying to decide between KW, Nitron, MCS and Ohlins until I spoke with Anze Suspension who helped solidify my decision about JRZ.
He said all his Lotus Elise guys run them, BMW Motorsports has been running rebranded JRZs for a long time, all the top tier true coilover companies are cousins and every other suspension can go right in the trash bin.
