Hey guys I have a simple question will a set of ET Sreets on a BONE STOCK GTO with a 6speed hurt the IRS?

The rear end on these cars are good for 500-550RWHP with a set of sticky tires and that is with a M6. The A4 rear ends will be able to take alittle more since the tranny takes most of the abuse.

We've had stock rear ends do deep into the 10s for the A4s and low 11s for the M6s.

Well there is one way to find out, build a wicked turbo motor and make pass after pass, each time turn the boost up a little and launch a little harder each time.

Knock on wood. Mine is holding just fine with 500+ to the rear wheels. I have plenty of issues with traction but with my Nitto's and a preped track It does fine for me.
