I got to try these pistons this weekend on my worlds edition RC8B. It was the first time I had driven the buggy but I have an RC8 that had a good set up on it that I am comparing it to. The track was in real ruff shape with some narley ruts and many small bumps on the straights and it was dry. I was running 35wt 1.2 comp 1.4 reb in the front and 30wt 1.3comp 1.4 reb in the rear. It handles all the bumps great! I did not hear the buggy bouncing around at all. It would stick all of the landings without bouncing. I turned in one of my best laps despite the terrible conditions! I cant wait to get my buggy on the track when it is race prepped and watered. I do have one question: what does drilling the rebound pistons do. I have 1.4 all aorund do to a mistake I made when I got them but it handled fine.
