Despite the simplicity of the task, setting up a vehicle's suspension for drag racing can be deceivingly complex. See, all that power needs to get down to the track somehow, and doing so requires a healthy respect for Sir Issac Newton. Hot Rod has posted an article that's probably the best introduction I've seen to the topic, including what qualifies as rigorous mathematical analysis for the 1320-foot set (ease up - I'm just kidding around). For those inclined to skip to the end, we find that weight transfer and locking diffs are good, but increasing the coefficient of friction (i.e. bolting on sticky tires) trumps all. That, of course, is why DOT-legal tire classes are so popular nowadays; limit the tire size and composition, and the game becomes much more interesting.
