I don't have much personal experience other than watching my friends laptopping from underneath a car. www.dorikaze.com is a forum for drift racing that a lot of my friends frequent, and there's bound to be at least a couple knowledgeable people in there. Be warned though, there's a lot of grade-school antics, meming, and sexism, and the smart guys are used to curtly fending off stupid questions. So do a lot of reading before you start typing.
