2010 Run to the Coast - 1979 Pontiac Firebird Trans Am Autocross
Here my Trans Am runs the autocross at RTTC 2010. This felt like my quickest run, but as luck would have it, there was some error with the timing so the run did not count. Note that the car shifts out of first gear; the transmission decided it no longer wanted to use 1st gear past 2500 rpm that day, which greatly hindered acceleration.
