I used to drift mine everywhere, uge can back this up wet or dry, and as he said you had to comit to the corner, alot harder in an underpowered car but more then possible..
The original diff was the best... till i smashed it, and none have since compared... the last 3 have been turbo ones but they didnt lock up as well as the original... i now have a nismo 1.5way mechanical.
