What is your ideal suspension setup for track oriented fun? If you don't mind sharing
Ideal? Money governs all. A set of Reiger Tarmac spec coilovers cost more than a high mileage car at this point. Custom dampers and springs would be the best bet but not many want to spend that dollar amount.
Track Only Car?
There are so many coilovers available that its user choice. Biggest around here seem to be KW V2/V3's, Bilstein B16's, Neomax, Suspension Techniques, KSport, Fortune Auto, ISC, Silvers, Meister R, BC Racing, AST....I have a few friends that i have tracked with and nearly everyone has a different setup.
I run HSD MonoPro's with 350/300 spring rates and its flat on track. Have them set to 9 clicks from soft up front and 10 clicks out back. As much camber/caster as possible, toe is zero but have seen some run 1/16 to 1/8 out for turn in. Still dialing mine in but i ran the same times i did with the B8/Swift setup without going balls out. It feels much more stable, very little body roll and grip is fantastic with 225/45R15 Hankook RS4s. My fast time at Summit Main is a 1:30.7 on 93 octane. Average times are 1:32s.
Dual Duty?
Bilstein B8 + Whiteline/Swift springs + Camber Plates or bolts. Eibach or Whiteline rear sway bar. I absolutely loved this setup. Compliant enough for a daily driver but can handle track events with ease. Dial rear pressure to induce oversteer.
Daily Driver?
Bilstein B8 + Whiteline/Swift springs
Comfortable enough for a daily grind with some sporting intentions. Not slammed like alot of lowering springs. It will stuff the camber into the -1.5 to -1.7 range on tolerances alone. Add camber bolts to get more than -2.0 if needed.
THIS IS MY OPINION AND OTHERS MAY FIND DIFFERENTLY. PLEASE TAKE ALL AVAILABLE INFORMATION FROM AS MANY SOURCES AS POSSIBLE TO GAUGE YOUR NEEDS FOR SUSPENSION SETUP.
Just to make sure as alot of people track these cars and it everyone will have a differing setup on how they like the car to feel on track.
