Spring/Susp. recommendation- riding on rear bump stops
I run in the advanced solo class at Robeling Road raceway, and a recent video revealed that in the long steady-state right-hand sweepers, my rear end was compressed so much, I am riding on my rear bump stumps.
This seems to explain why I feel some understeering in these turns.
I am running the stock springs, Koni "yellow" sport shocks, Tri-Point adjustable front swawbar, and 265/40R16 R-compound Kumho tires. The car weighs about 2830-lbs. wet or 3040-lbs. with me in it. I dial-down the Koni's and put on the stock wheels/tires for weekend driving.
I think the most economical solution would be to install the Ground Control coil-over conversion, but I have no idea what spring-rates to get for the front & rear.
Is this even a good thing to do ?
If not, what suspension kit (shocks & springs) would you recommend ?
TIA,
:-) neil

I don't think you're on the rear bumpstops but it's easy to check. Put some zip ties around the piston rods on the shocks; push the zip ties to the bottom against the shock body. After driving some laps at speed check to see where the zip ties are as they will signify the largest displacement that corner of the car saw. If one or both are crammed into the bumpstops you know you are in fact using all the suspension travel. Even if this is the case it's not what is causing your understeer.
