I am running an older chassis with no rake in the engine/trans and the back of the car is always bottoming out. I have been all over the board with torsions and I don’t feel like I am driving it too hard. The pan under the shift cover is 1.5 inches lower than the belly pan and the pan under the case is 3 inches lower. Is it worth the time to put some rake in the back of the chassis? How much are new cars running?
