Metal removal at rear, opinions

[4000GT]

NoHachi Wrote:Dicking around with the rear end is a lot easier to get wrong then it is to get right. I disagree that its done and tested. I haven't heard of any fast AE86s on the planet with the S13 rear end doing well in any kind of timed motorsport, but chime in if they exist.

Is a swap like that even allowed in class?

How are you doing in class now? There is a lot of time in setup/tires/data anlysis and driver development. Whole seconds in stead of the tenths you'll find with further weight reduction. How far are you along that curve? Might be a better place to continue looking.

To answer your questions, yes the swap is allowed, its CC driven.

Im probably is the upper quarter but 3 seconds a lap off the top guys. I still have a lot to gain in seat time and full slicks, only on R888's at the moment.
