I am using V2 shocks with Avid white springs front/rear. The shocks have been spring balanced front and rear. Rear shocks are mounted to the inside hole of the lower arm and on the inside hole of the rear shock tower.The front the shock is mounted to outside hole of the front arm and the upper middle hole of the front shock tower. I am using RPM 2 way pistons all around. The equivalent of #2 in front and 1.5 in the resr with 32.5 in the front and 30 in the rear. On a very technical, highh bite, well mainted, indoor clay125x65 track using bar code Gold slicks with aka inserts front and rear the cari is dialed as far as shocks. It jumps well, doesn't slap, corners well, "floats" over the rough section while maintaining tire contact.
