If its going to be raced then you want it capable of that kind of droop but set up low for the lowest CoG you can get away with, most modern day trucks are indp. susp. so take your pick, but fabbing up your own suspention to a small spaceframe chassis would yeild better results as you can then make it exactly how you want, maybe you should look at those 1500bhp things they race up hills in iceland and get some idea's off them
