    What is the max HP the rear diff can safley handle once broken in?

    Ill take all theories. But does anyone have solid data? I'm already close to 600 hp at the wheels. So I'm hesitant due constant complaints of new diffs failing. I went through the same problem but my car came with around 600 miles on it. "Not broken in properly". Test drivers don't exactly take it easy on the test drive. I know I don't. But I broke my new diff in properly and haven't had a shred of an issue yet. Should I be worried?

    I wouldn't, not at 600. I'm over 700 and I'm not stressed right now, especially since I'm not drag racing my car.

    Ill drag my car occasionally. But I usually am also on street tires. So launches are mild.

    Yep. Steer clear of slicks (even DRs) and you'll be good.
