I gain more respect for GM everyday. There is something to be said for the reliability and availability of GM parts. That's the beauty on an LSX motor, stock syle pumps, and corvette brakes. With that being said, every car has so many custom touches that it doesn't take much to end your day. After all I broke a stock GM power steering pump at Spring Mountain as well. In fact, it's the same type 2 pump Steve broke at the Optima Challenge. I know his was a turn one already that had seen better days. Not all stock parts are engineered to be pushed to the level some of us are looking for either. I've already made the bed I lay in and you won't see me running the one lap of america.
At the end of the day, your only as good as the sum of your parts.
