Been thinking about a double adjustable shocks for sometime now and as I am going from 9.5's to hopefully 9.0's in the near future with a 572 combo I will probably need them.

Previously had limiters and old 90/10 shocks and was unloading the rears several feet out from the line. Fitted Koni SPA1's to the front (really needed better, but it worked OK at the time).

Have looked at the Santhuff's, but was a little concerned by the 3.5 inch travel compared to 5inch with Afco's. What do you guys think about that for my performance considering I am footbraking.

Anyway, slomo video of the car running 9.5's
