1. Great! The MCS instruction document is useful.
2. Got it. It’s best to follow MCS/BW recommendation of always resetting all R and C to zero before setting the new R and C settings to minimize the chance of having offset damper settings.
I would try setting the forward rake like I recommended above. You only use the plastic jack pads to find their center point on the bottom of the jack pad and transfer that point to the actual chassis. Set the rear height first and then set the forward rake by adjusting the height until the front jack pad chassis point is 3/8-7/16” below the rear jack pad chassis point. The pic below of my f82 has the front jack pad chassis point is 0.47” below the rear jack pad chassis point (f82 is 0.4-0.5” jack pad delta). This car hbeen corner balanced so the cross weights have the lowering heights off a bit from one another. I don’t have any great e92 M3 pics but I’ll throw in a pic or two. Plus a f22 m240ix that does a good job of showing fxx forward rake.
Setting the forward rack properly will address your front-to-rear ride height differences. It will address your two points. It will give you more suspension travel and, even with stiffer springs, you’ll want to run this same amount of forward rake. All of our cars are set with the proper forward rake for the e9x M and f82/f22. I’m running F/R 700/1100 lbf/in (divorced rear) on my f82 MCS 2WR setup. My e92 M3 I’m running either F/R 700/1000 or 600/1000 lbf/in (divorced rear; different rates for different tracks) on my MCS 2WR setup. The last 2WR setup is on my wife’s f22 m240ix street setup with F/R 500/800 lbf/in (divorced rear) with reservoir N2 gas pressures set at either 85 or 100 psi (100 psi if driving more aggressively in the twisty mountains, no cavitation felt). Street damper settings are Front 4R/4C and rear 5R/5C (from 0 or min damping) and she absolutely loves it. I’ve actually created a cornering monster! I had the 2WNR on my f82 for six months while they were trying to address the valve closing on the rear damper. A different coating on the valve fixed the noise issue. I then switched to the 2WR. I thought about 3WRs but went with three 2WR setups.
BimmerWorld/James always have the best builds with the best setups. The custom welded-in roll bar on my e46 M3 track car looks like it was professionally built for the Speed
