hehe, I know, was just stirring the pot…
RW doesn’t do much in the susp development. Typical 911 mod include full monoball upgrades, camber and castor shim plates,diff spring rate, etc. Just basic shit really. The rear design of the later 911’s and 964(non torsion bar setups) is a close resemblance to your m-car setup. Wheel ratios vs spring ratios are not 1:1 which can make for some tricky tuning in some cases. It is common practice to shove are much rubber as you can fit under the fenders on the 911’s(pre 996) with a full monoball suspension and some GOOD dampers. they chassis just seems to respond well to the changes without too much of a headache.
Most guys setup 911’s for stupid rear grip to counter their tail happiness tendency, but we know it creates a host of other issues. 911 are a different type of car to drive on the track and really take a little learning curve to get down. The roll dynamics of that rear engine setup toss wrenches into the mix. It was “the” chassis I learned to track in and was notably different when I went form that to the 944’s.
I should get you some seat time in Mikes RSA this year for comparison. Interested?
