at the release of the trans brake the wheelie bar rotates 9 inches. Which at that point is too low to the ground I cannot raise the wheelie bar anymore so hopefully eliminating some of the rotation will stop it from unloading the tire when it plants the wheelie bar
The spring is there to hold up the car.. you dont want 2 opposing forces on the spring.. the shock controls rise .. you might have to move the wheelie bars up higher
The shock controls rise but if you are at the limit at the shock the spring must get stiffer.
look at stoping rear end rotating
If your at the limit of the shock you have the wrong shocks.. period... if you put a stronger rear segment on it that pulls down on the body.. which is really lifting the axle.. opposite of what the front segment does
