1983 911SC Track Car Alignment Anomaly


Vehicle Information: Model: 911Porsche; Year: 1983; Body Type: Targa; Total Mileage: 65,000;

I recently went to a Drivers Education event at Road Atlanta. After twosessions on the track, I noticed the rear driver's side tire rubbing thefender. Also, the rear tire went from negative camber to positive camber.I had local track side shop do a new alignment that night. Sunday morningafter two sessions on the track rear tire did the same thing. Had localshop do another alignment that day, and they said the bolts were nottight enough. After one more session the rear tire kept the negativecamber.Is there something besides loose bolts that would cause the rear tire togo from negative camber to positive camber? A week previous to thedriving event I had Turbo tie rods installed on the car. Would theyautomatically align the rear suspension with the tie rod installation?Modifications on the car include upgraded shocks, sway bars, lowered rideheight, track alignment, track tires, front brakes cooling kit. Anyinformation on why the rear suspension kept changing would be mosthelpful.
