Mistake 1- Let my friend drive the b4.1, he smacked into a sct or vice versa and hit the concrete barrier broke the bulkhead.
Mistake 2- Decided to upgrade to SCTR aluminum bulkhead instead of the stock plastic one.
Mistake 3- There was a speed trap setup at the end of the front straight, so instead of watching the car, I was watching my speed (got up to 26mph!)..bang!!
The alum. bulkhead survived w/o a scratch, chassis didn't. I've since changed back to the plastic AE bulkhead, since alum. also added weight that messed up the jumps...
