I'd love to race me some Slay in GT-R come April I know you like beating them in the F.

Sounds like a plan.

The LSD is a torsen type. There are gears. There is NO slippage. The term limited slip is kind of a inaccurate description IMO.

There is no way an non lsd isf has the ability to have better 60ft times than one with the lsd... I dont understand what your saying.

As long as you're not spinning, whether you have LSD or not doesn't matter. If you're spinning one wheel, then LSD will help. I don't have enough HP to spin so whether I go LSD or not doesn't make any difference in my 60'. Maybe in Juanca's case, the new 2012 has a slight revision of the TCU to allow a little bit of slip to protect the transmission?

Im also thinking that TCU might allow a bit of slip on the newer ISFs.

My problem with traction comes in the from of wheel hop. Problem should be fixed with a more aggressive tire setup next time the car hits the track. Shooting for a 1.5-1.6 60'
