"I don't consider 8 psi as low" Rebel at 2900 race weight that may be true but I know that my car at 3600 race weight is all over the track on top end at 8 psi. I don't think we know what his car weighs going down the track at 130 440 Brian how much does it weigh with you in it???
It weighs 2950 lbs. with me. I'll try a higher rear tire pressure next time at the track.
I checked the steering linkage and didn't find any play. It did seem like I had just a little in the front right wheel bearing. They look allright so I'll re-pack them. The front shock bushings look like they are falling apart, so it's probably high time I replaced them with a racing part. Any suggestions?
I ordered an algnment check tool kit, so I'll be taking a close look at the toe.

Have you moved the body height ever without having the front end aligned afterwords... that will kill your alignment... if you check the toe curve(in the MP chassis book) and it toes out at all during the travel it will cause the car to dart around and with low rear tire pressure it WILL get real scary... so you may have multiple things that are wrong/bad

In addition to blocking off the grill, fabricating a belly pan from the core support to the firewall would help a lot.
