I'm a little bit delayed making this post, but life has been quite busy lately with work and finishing our wedding/honeymoon plans. I autocrossed with Equipe Rapide on March 25th in Mesquite, TX. This was the 2nd Challenge Cup autocross on Equipe Rapide's schedule. As with Challenge Cup # 1, the event was run in the small lots of Resistol Arena. Fast run times were in the 30s range, but unfortunately, I was not able to post a competitive time due to breaking teeth on my ring and pinion gear on my second run. As you can see in the video, I downshifted to 1st gear in a slow hairpin. On the corner exit, when I upshifted 2nd gear, the ring gear broke which invoked some non-so-pleasant noises from the rear end. I had no trouble with the downshift or upshift, so the failure was quite a surprise.
I have a spare GM ring and pinion so I have the parts needed to fix the car (thanks Sam!). The car is up on jackstands and I am in the process of pulling the rear end apart. Hopefully, the car will be driveable again soon.
