I was at Mont Tremblant this weekend with my track car. It's got a stock 3 liter, 915 with Martin's shift conversion, great suspension setup. Weights around 2000 lbs. I came in from a run and the right rear tire had WAY too much camber. It was obvious it was broken and about to rain, so we loaded up and waited for the complete diagnosis for when we got home. Put it on the lift to find the rear control arm coming apart. I'll post up more photos and analysis when I get the arm off, but wanted to share these.
