I'm no chassis guy but just my opinion and that's all it is.... I don't think you will gain much in the way of wheelies by messing with ANGLE on a ladder bar car.Not like you can with a 4 link cause the length of the instant center is fixed... I would concentrate more on reducing unsprung weight on the front and playing with the front suspension travel and shock settings to get it to pitch rotate more. If it is hooking good and going straight why do you want it to wheelie more?
