i was just wondering if someone could explain something to me about using wheele bars on a fwd car. I know fwd has alot of traction problems because when the car launches, all the weight transfers to the back causing it to sag down and lifting the front end. Ive been looking at the design of sum wheele bars, and they seem to be able to pivot vertically at the points that they connect at the car at the back. I always thought that wheele bars were used to prevent the car from sinking at the end so that the weight transfer is minimal, but if it is able to pivot, wouldnt that defeat of the purpose? or maybe im looking at the design wrong...can someone explain this to me?
