I have a set of VRP pistons as I have used them in different cars before and really like them. I ran 6x1.3 with the soft bladders and as little rebound as I could get (about 10% front and rear) last Saturday and really liked the way the car handled. I added weight to the back to experiment and the car did not want to rotate. That said, I only ran the main and started last - sometimes the best position to avoid first lap mayhem. Picked off seven positions to finish 3rd with my first race with the car; even with having to rotate the car on the brakes to get it around tight corners. I am running 7/5/3 in the diffs and am really liking that setup diff wise.
