Might want to head over to ls1gto.com for more input but the axles seem to be the second weakest link in the drivetrain. The primary in the driveshaft. BMR Fabrication has been pushing there GTO to its limits and has an interesting bit of info on it on there website.

"I AM the way, the Truth and the Life:no one comes to the Father, except through Me"... Jesus...John 14:6.
I cant say I follow Aussie forums to hear about any problems.
I'm not sure that a handfull of people who make a few dozen passes in the 11's can say that the stock stuff is bulletproof or not. Heck, in my Honda I ran dozens of runs from low 13's to basicly high 11's on slicks over the period of several years on the stock CV axles. It took several years for one of the stock ones to fail and the other never did. However I know people who barely ran more than stock power and broke them more than once.
But when,I mean will a 12.50 A4 GTO break this stuff...
I've been following the GTO and Cobra IRS issues for awhile....Bottom line, be smart. If the car wheelhops even a touch, get out of it. You would be surprised how many people stay in it when the car starts to get wheel hop....stupid....
Thanxs for the feed back, I was wonderig if the cts v would ever come automatic, looks like that would just be another weak point. Since IRS is here to stay, it can only get better if the manufacturers would step up and fix this problem in the engineering stages.
