I lowered my ride height after doing a lot of work on the car during the winter. I had 2 1/4 inches of wheel clearance (I know that's not exactly scientific) before I tracked the car. After a weekend of racing, the clearance is down to 1 3/8 inches. If this is too low, what would the symptoms be? There are no signs of the wheels scraping against the upper wheel well. However, as reported in an earlier post, when I hit the bump at turn 1 at RA or any rumble strips at the apex, I hear a deep chattering sound when the car is drifting from the apex all the way across the track to the exit. The shifter also shakes violently. Would this happen if the shock was bottoming out? By the way, I have the T-1 suspension kit with Sachs shocks. I also did work on the CV joint and could it be that the axle shaft is bottoming out in the joint?
