I am looking at buying a GC coil over kit for my car and would like advice and opinions on spring rates.
My current setup:
Bilstein Sports
IE Stage III springs 315F/570R
IE rear spring spacers
Urethane bushings all around
M3 offset control arm bushings
IE fixed camber plates
21mm front sway bar
16mm H&R 3 way rear sway bar (set full stiff)
The car has too much body roll for my taste. It doesn't handle well in quick transitions and I have grown accustom to throwing the car into turns, Scandinavian Flick style, to allow the suspension time to set before I actually start to apex.
What I do love is I can mat the gas at corner exit and have 0 worries about oversteer.
I talked with GC and they recommended 550 front and 850 rear but I have read where many people have issues with oversteer. I saw a thread where one gentleman was running 550/630 with a 25mm front sway bar and no rear sway bar and he loved it. Has several SCCA wins with that setup. Then I have read that e30s love 150% difference in springs which is what GC recommended...so.....?
Pelican recommends 450/500 for an "all out road race car"
The car is a secondary DD and ride comfort is not a concern. I would like to retain the exit speed capabilities while reducing body roll. Goals: to handle quick transitions and sweepers (50-60mph) while maintaining neutrality. With that said, I was leaning towards 550/650.
Thoughts, input, comments?
