have seen a few threads on here and on other dites about geting better diffs for drifting and drag racing, what exacty is a diff (differential), and what does it do? what are the benefits of a better one?? Im sure this has prob been discussed before
Lots of reading there but some good animations of how differentials work. This site is quite good TBH :)
