Anyone have anything to say about this piece ?? I am looking to buy one for my SE-R and Maxima, the VLSD in my SE-R is pretty worn out and at 220 bux for a PGrip its a good deal. Is it durrable ? Does it work like a Torsen LSD ? I def need it for road racing and autoX in my Max, spins the inside wheel too eassy. Mike Jez
