[QUOTE=teknorc;13535720]Theoretically, these should have _less_ pack than the 8.3 piston. The 6.5 config will feel the same on the bench, but on the track it will have more traction and be more consistent (at least in our testing).

What I think is going on is that the 8.3 have too much pack or don't pack at the right time. The 6.5's seem to settle better.

One important note is that the 6.5 pistons work best when you move the shocks to the outer hole in the arm. This increases the piston speed and alters when the piston packs.

Try 450-500 in front and 350-400 as a starting point. The stock pink F and red R springs seem to work well as a starting point.[/QUOTE

Been running Mo's setup lately, but my track has been extremely rough, bumpy and dry. The car skips around and pops up a little more than I think it should. Would the 6x1.5 pistons be better for this condition?
I would also like to know how on Dannys setup, he is running 106mm front droop? I have to lengthen the shaft by unscrewing the shock eyelet from the shaft a few turns to achieve the 106. I like the extra droop. It seems to help in the rough areas of the track, but I've actually broke 2 shafts off now, flush with the eyelet by doing this.
