If they are 17 in, you really need to start at 30 -32 pounds and check them hot with a target of 36-37 pounds. If they are 15in then the target heat range is 30 pounds as a general rule. If that doesn't help, you will need more swaybar in the back or less in the front, heaveir springs in the back or less in the front. You might try more pressure in the rear but if it is severe, thats probably not going to get the job done.

Hey Rob,
For perspective my street wheels and tires are at 24fr 26 rear, and the DOT track 17s are at 22fr and 24rear. Tire pressure and alignment play a big role with these cars, and also pressure differential between front and rear. BDR also offers a set of stiffer springs if you are interested. My car with the M3 bits still felt like a sponge. The springs really woke up the beast, no regrets.
Good luck and enjoy the ride,
Richard Bailey
