I have been looking up Diffs and reading on them from all brands, The problem is that no web sight really explains what type is good for street or strip, i know that this is a pretty broad subject being that there are so many Mustang Drift/Grip/Drag/ auto x guys around but what is the in between all around choice for the guy who likes to do a little bit of everything in auto sports. Thanks hope you can help.
