Stress on 7.5" with MT ET Streets
Hi all. I'll start with an embarrassing disclaimer that I've never owned tires this aggressive so I have a few rear end 101 questions regarding my set up. My car is a stock geared M6 (only exhaust on car), with MT ET Streets. Like I've said I've never owned tires this sticky before and I'm actually pretty surprised I can't break them loose on hard rolling acceleration (haven't bothered to straight up launch it yet out of fears of the 7.5"). It seems fairly obvious the 7.5" rear is inadequate on these cars. I do not have any intentions on dragging the car, but that's not to say I won't have fun with it on the street. Do these tires present a significant threat to the longevity of the rear? I was going to get a girdle just as an insurance policy as I personally do not see the need to buy an upgrade rear for my intended use as a fun cruiser and not a drag car.

I babied along a ten bolt for quite a while. Once I got it to hook, it died. It really depends on your shifting habits. How hard you hit second and third, that sort of thing.

7.5 will hold up fine on sticky tires with an auto , M6 is where the problems come because they can shock the drivetrain pretty hard depending how you release the clutch.
Obviously you cant be doing clutch dumps at 4,5,6 grand like you can with an aftermarket rear keep it 3 grand and under and learn how to just barely slip the clutch for a millisecond on release to keep rpm's up enough not to bog and no lift shifting is definitely a no no granny shift that thing and start saving for a rear or keep a spare stocker on hand all the time.

I may just bite the bullet and buy some different wheels off of craigslist for cheap. The wheels and tire combination on the car look great but for practicality reasons not the best choice (I bought it this way). I definitely do not want to spend any more on repairs for the rear. I'm completely clueless on how to repair anything in the rear so I'd probably have to pay a pretty penny on the repair. I think buying a cheap set of wheels sounds worth the piece of mind.
