    I have two graduated cylinders, connected by a tube at the bottom with 1/2" rubber fish tank line. I put water with food coloring (to make it easier to see) in there, and fill them both ~3/4 full. I shim under till both cylinders read the same, at which point I know they're level. I try to figure out which scale is the highest, and then use all the others to compare to that (shimming the others up). Once everything is shimmed up, I zero the scales so they don't contribute to corner weights.

    As shims, I use whatever the cheapest vinyl floor tiles I could find at Home Depot were (IIRC it was like $30 for 100 of them). They're ~1mm thick, so I can get reasonable leveling, and they're slippery-- so when I raise/lower the car, it doesn't get stuck high with the camber curve, and if I, say, adjust camber, I'm not fighting the friction of the tire on the scale-- the floor tiles just slide against each other.
    I'm about to put porsche brakes on, and couldn't be bothered with fiddling with the logo/repaint either! Did you get track pads sorted out through FCP? They seem to be out of stock of the good stuff for 6 months or so. My last conversation with a rep was that DS11.1's were backordered from the factory, not that they weren't going to carry them any longer.

    Great idea on the vynil floor tiles, I'm going to try that out! Do you level left right/ front back/cross? Could you use 4 cylinders and not have to level the pads multiple times?

      Haven't needed replacement pads yet, so will cross that bridge when I come to it.

      I started out with 4 cylinders, but it was way more difficult that way. With 2 cylinders, I know what the level is when scale. With 4, whenever I would change one all 4 would change, and I'd have to figure out what the new equal amount should be. Plus more tubes to trip over and fluid to fill. It was just a mess.

      With the new system, I just leave one on the highest, and then compare, one at a time, each scale to that. Quick, minimal fuss, easy to determine if level, less stuff to store.

      ... when we move, I'm going to use them to level my new 4 post lift and then probably get rid of them. Once I know the lift is level, they are no longer useful.

        On the garage I'd only offer the standard advice - you can't have too much space, power or light. On light I did ok in our build, but I do wish I'd added more outlets. I did run 220v to two places, so that should cover me for any future lifts, compressors, or EVs. And like I mentioned before, the space where I'd put a lift is 8 inches of 4000 psi reinforced concrete. I'll have to post up some pics in my journal thread.
        Well, if you hold off on brakes till the 17x9.5 ET35s ARC-8s arrive, I can tell you if they'll clear the 996 brakes. I also hate to buy with the hope that it'll fit, but I couldn't the answer find the answer anywhere and Apex said I could return them if they don't.

        I'll be running 220v for sure-- Lift, air compressor, and realistically EVs are going to take over while I live in this house.

          gotcha, that makes sense. sometimes simple is best.

                I have very intentionally never slightly thought about that.

                    I did a bunch of mods over the winter. The most significant (for me, anyway) was the Fat Cats suspension.

                    Because of moving, it's been hard to make actual progress on getting the car 100% (was driving for a while with no sway bars connected, etc). But, as of last week I'm installed, bump/droop ratios optimized, corner balanced, aligned, corner balanced again, and preload dialed out. I've put ~100 (street only so far) miles on the car, and and comfortable giving very early impressions.

                    My complete setup is as follows:
                    Fat Cat Motorsports Stage 3 Coilovers (every option they offer)
                    Springs: 375 FL, 350 FR, 700 RL, 650 RR (equal frequencies left/right, 1.97hz front, 2.10hz rear, 75% front roll couple with sway in middle of adjustment range)
                    Ground control street camber plates
                    Ground control street RSMs
                    Ground control Front sway/bushings/brackets/end links
                    CSL Rear sway/bushings/brackets, with home made adjustable end link
                    Sealed monoball RTABs
                    TMS Sealed monoball FCABs
                    Bimmerworld sealed monoball rear adjustable camber arms
                    CSL Kingpins

                    I'm running at 60% bump, 40% droop up front, with a .5" rake (seem to be optimal for high speed oversteer/understeer), which puts me at ~14" front, 13.5" rear. In terms of alignment, I'm at -1.5 up front (this will be pyrometer based set more negative on track) and -2.0 rear (this will be left alone on track). I'm super psyched to have a setup that lets me run high enough to have a reasonable street camber, with the CSL kingpins-- should be a pretty killer camber curve and let me get away with meaningfully less static camber on track! Rear geometry should also be pretty good, with the CMP bushings raising the subframe and minimal drop. My geometry is also pretty rigidly held, as the only bushings in the entire setup are rear upper control arm inside bushing-- everything else is a sealed monoball (shock mounts and drivetrain mounts are still bushed/stock, so NHV is pretty minimal).

                    Onward to initial street impressions of the FCM setup:
                    The only word I can think of to describe the car is unflappable. Nothing seems to phase it. If you've ever driven a car with too much tire (the level of grip is more than the suspension can deal with), this feels like what the opposite would be. The closest analogy that fits is a stock FRS/BRZ/86, on the default prius tires-- only with PS4S levels of grip.

                    It is remarkably different than any setup I've driven before. And I've been all over the map-- Motons and JRZs on the e36 track car, TCKs and Ohlins on this car, Stock springs with Koni yellows on the M5, Dinan springs with Koni yellows on the M3 wagon. I can't say it definitively till I've been on track (after which I'll make a dedicated thread about the setup), but so far this setup feels faster and easier (to drive) than any of the above. Plus, I'm excited to have a setup that just valved for my specific corner weights and spring rates, so I don't have to mess with adjusting shock valving before/during/after track events. It's just correct for the car.

                    I'm pretty excited for this setup-- don't think I'll be changing again. I look forward to seeing what it's like on track!

                      Congrats on reaching this point. I'm surprised you're on poly bushed camber plates and rsms though.

                        The monoball camber plates are just too much NHV for the amount of precision they add, for me.

                              Including the hybrid styles? I'm planning to replace the TC Kline plates currently on my car and NVH is a concern.

                              Great job and thanks for documenting all of this. I can appreciate the reasoning behind the choices you've made. Looking forward to more reviews of the suspension!

                                Ha... more involved question than you might think.

                                I found a line barely barrel springs that eibach makes, which they call their extreme travel line. That allowed me to use a shorter spring (6" IIRC) up front, while still having sufficient travel, which puts the perch above the tire at my desired ride height, allowing me to run bigger tires without compromising offsets (lets me run an ET35 front, which allows me to not have stupid camber to fit 285s). So, my front left is an eibach extreme travel 6" "barrel" spring. Eibach 0600.2530.0350.

                                Front left was tricky because the extreme travel line only comes in 50 lb increments.... but then I realized that GC sells and extreme travel spring (made by eibach, though they don't use that branding-- but visibly the same thing and I confirmed that they were with GC) in 6" 375 lb. Ground control GC150.64.66.


                                Both fronts are either 65mm or 2.5", I forget which (and am pretty sure most spring companies use the same thing here anyway. To fit that on the H&R shock body, I'm using Ohlins spring perches-- same thread pitch, so it's plug and play. Still using the H&R lock ring, because it's free.

                                Rear left is a TCK 700 lb beehive from my old TCK coilovers. TCK TKE 360 700 R.

                                Right rear is a GC linear 650 lb spring... I think 6"? With some of their cones on the top side, to protect the chassis from the spring.

                                Both rears are sitting on the H&R rear ride height adjusters, because they're really nice-- let you adjust the height without taking the spring out, or wheel off, which makes corner balancing way easier.
