582 hp is fine so long as it never gets any traction, BUT if it does then that is more than enough to destroy it.
You need at least an 8-3/4 axle with that amount of power.
I agree. Unless you're slicks or similar and just driving on street tires and smoking them once in awhile you'll be fine. Currently I have one with close to 500hp and over 500tq and it's been fine for quite awhile. 3.21 gears. I've had three HP 360's with 8.25 rears and street tires with sure-grip and they held up fine for thousands of miles.
