What does one have to do to get a 535i to have the same crisp, turn-in like my old 1986 Thunderbird Turbo Coupe? I have Racing Dynamics sway bars, new Bilstein struts, new thrust arms with BavAuto hard bushings, and 17" Michelin XGTZ Pilot tires on my 1991 535i. Even with all of these modifications, it is not even close to offering the same sharp, turn-in and buttoned down feel my old Turbo Coupe does. My Turbo Coupe has the factory springs (even though I transplanted a 5.0L Mustang V-8 into it), Koni adjustable shocks and struts, huge (1.31" diameter in front) factory sway bars and 15" Michelin XGTV Pilots. The turn-in on this car is IMMEDIATE and very stable.
Even with all of the modifications to my 535i, it still feels like the front end is dancing with a drunk partner (back end) that's always a half step behind. Since I believe sway bars play the primary role in the relationship between turn-in and body response, my first thought is to put larger sway bars on my car. However, I think that the largest bar (front) offered by Racing Dynamics, like all other aftermarket manufacturers, is 27mm in diameter. I'd appreciate any thoughts or suggestions here.
P.S. Other than the above complaint, I absolutely love this car!!!
