A couple weekends ago I got the chance to drive another Mustang prepped VERY similiar to mine. Same Maximum Motorsports suspension, same size wheels/tires, torque arm, same sway bars. The main difference was slightly different spring rates. I have 425F/275R. He had 450F/250R. While driving his car (on an autocross course), the most noticeable different was mid corner grip. Basically at the same speed and slip angle(think long 50mph sweeper) my car is right on the edge of grip but his car had enough grip to actually turn into the corner. I'm wondering if this is just in the spring rate difference or if it's alignment related. I ordered a set of 450lb springs to test out and see what happens but I assumed with the collective knowledge of the forum someone would be able to tell me what I could reasonably expect.
To add a little context to this. I originally had 425F/325R with a Steeda front sway bar and 1" rear sway bar. After talking to Jack Hindley at Maximum Motorsports he suggested I go down to 275 on the rear but with a 1 1/8" sway bar. He also had me switch to a stiffer Eibach bar on the front instead of the Steeda. His reasoning was to improve my roll couple percentage on the rear. These changes made a massive improvement. Would adding front spring rate now offset this change and make it worse?
