diff advise

hey i have been doing some looking into getting a diff strictly for circuit (GRIP)
ihave no interest in going drifting or drag or anything other then taking turns fast and keeping as much grip as possible
ive been thinking 1or a 1.5 i also hear a vlsd is a really good way to go
that being said i would like some info and feed back
also would a aftermarket diff change my final drive?

1.5 dude.

Get a 1.5 and you won’t regret it.

VLSD is garbage. and burn out quick.

I’ve got a 2 way and i love it.

1.5 is the way to go for grip. vlsd’s arnt good for track use because when they get hot the viscus fluid starts to bubble and becomes a hunk of crap.
