In stock I do drive my belt as loose as possible (which is extremely loose). This makes the car fast out of the corners and still gives it a decent speed on the straights. I drive either P2K2 or MVP and mainly a 88/25 gear. Fast enough to drive in the top of our local races and close to the top in the bigger races.
The one thing missing, which could be a benefit, is an aggressive feeling, even though the car is still fast. Any ideas?!
