Suspension Setup - Time Trials/Road Course, Suspension Component Recommendations for V8 Options

[Runner]

Fellow track drivers:
Need some ideas on general suspension components for a V8 track car that you have had good success with. Anyone running a V8 car on road courses that can give me some general set-up ideas would be great.

Thanks,

Mark

kyb is an econo shock. koni or Bilstein are required to dampen the stiffer springs you need on a v8. Grant is on teh right track.
I would recommend 22mm front torsion bars, 21mm sway bar
rear should switch to a coil over set up to enable proper corner balance with 250-275# rear springs over bilsteins. 15mm rear bar
I hope you have vented front rotors

Hey Sean:

I think you are really getting close the the right solution with your recommendations. Of course, only on-track testing will give the final answer.

I Have never seen anything too good to come from KYB and you bring out a VERY GOOD Point that when spring rates get Higher, MORE dampening is required!

I also think your front-end T-bar + swaybar numbers are a good place to start. With my experience of YEARS of understeer with my V8 914, I would tend to go the heavier 275# rear springs to see if the rear will get UNSTUCK!!

I'm running stiffer all around, but in the end, HAD to add a rear swaybar to balance the car......now if it would just STOP RAINING here in SOCAL, I could run the car and KNOW i'm getting the handling to come right. Next week-end at Streets of Willow is another Rain-out!! DANG!

I'm with you on BIGGER VENTED brakes! I have the 12.19" x 1.25" Wilwood rotor and have read front temps of only 450 degrees after a session on the Streets of Willow Springs. With the same in the rear, the temps are still in the 300 degree range. There's nothing like empirical Data: My eBay Tire pyrometer also had a probe for High temps.

Best,
Terry
