I got bumped out into to the more advance group so I couldn't run with my dad. However, in the straights, I had no chance that car is fast, but in the turns I was able to take the other red M3 in our group and that was with having myself and my instructor in the car (he was 290 lbs) my car was weighted down. I am adding parts to the CR to increase the power a bit, but the handling is amazing from the factory, I am only adding a front x brace to it the suspension for now. Intake, test pipe, exhaust, and flash pro on the way and will have Evans tuning tune it. He did an amazing job on my si.
