Bob,
I intend to run my car at the road course Roebling in July and some autocross next week. Do you have any general ideas on setting up my car from street to track? It seems a little soft now. Is it just a matter of tightening up the springs at the coil overs?
You don't have to do much with the car, but replacing the springs with stiffer ones is the best route. You can't make springs stiffer by an adjustment - it only changes the ride height. If you're "serious" , get a separate set of shocks, springs and tires/wheels for the track.
