Im sorry to hear about your losses to cavaliers and the likes. I just two days ago raced my friends red cavalier (which was stock), and I murdered it! It was a race from a standstill, with one of my friends at the "finish line" By the time I got to the "finish line", he was at least 4-5 seconds behind me, and i was well past 85mph.
Just thought i would share the success story
