well I don't know about autocrossing or the classes involved with that, but LSD's are sweet...almost one of those mods everyone should consider so I think of it this way. $300 now to get it with the motor? or $1000 later to get a KAAZ or Quaife or whatever with installation by a tranny expert...


Now, I don't know how good an OEM limited slip is compared to and aftermarket one...but if they are theoretically the same and your just going by price, paying 300 now is the better way to go...
