well, when i said loose.. it's not "loose" as in the diff would be slipping, but "loose" as in the diff can have/execute differential action easily.

settings diffs for races is more than just "loose for low grip surfaces and tight for high grip tracks". in my case, it has always been just try to drive your car around the track then adjust your diffs according to what you want. i just use the quoted statement above for a good starting point for my diffs.


@Airflow

yes, generally, a looser diff would have much more grip but at the price of speed. the looser you set your diffs, the more it will be prone to slippage, and thus loss of speed. so if you want to have quick launches, then have it "tighter", but again, compromising maneuverability.
