I made back last night after working as crew chief on the #35 SSF Auto Parts BMW M3 Lightweight and what an experience it was!
We finished 2nd overall, which considering the circumstances wasn't bad. We arrived to compete in EO which is the 2nd fastest class. It wasn't until 1/2 hr. into the race that we were told we had been moved up to ES which is the unlimited class and allows for racing slicks (didn't have), could change more than one tire per stop (didn't bring the equipment), and could use a refulling rig adding as much fuel as needed (in the shop because EO you can only add 10 gal/stop and have to use cans). By the way, the only difference between a Lightweight M3 and a regular M3 is 50 lbs.
So we made the best of the situation. In the morning we found ourselves 1 lap down on the leading 911. Unfortunately we lost 3 more laps when we had to change four tires and front brake pads with 2 1/2 hours to go. We were able to make up one of those laps, but there wasn't enough time left on the clock. We finished in 2nd overall, three laps down. The funny thing is, if we had been allowed to compete in our original class, we would have won that by 50 laps!!
It was long, tiring, and a great experience - here are some pictues
