Default broken 10bolt people

for those who have broken thier stock rear, im just curious of what kind of stress it was under when it broke. like what kind of 60's were you running and the amount of power to the wheels, launch speed, A4/M6. im just trying to feel out what might happen if i go back to the track with some decent tires. thanks

You'll be on borrowed time.

I put 285 nitto 555r's on and one hour later as I was on my way to the woodward dreamcruise...I was rolling at about 15 mph and I dropped the clutch at around 4500 rpms and it broke right then and there. That was before the H/C/I. I only had a cutout, catback, trextrailia clutch. 6spd obviously.

I've broken two carriers. First one went on launch when I was cam only (376rwhp), on BFG's, launching at ~3k rpms. Second time, happened sometime between the launch and the entire run because when I went to stage again, I heard a clunk in the rear during my burnout. This was with the H/C (411rwhp) launching at ~3krpms again on BFG's.

Sucks. Did you have to get towed home or could you limp back?

Torsen? That's what went in mine. Stripped one of the worm gears completely and then the teeth went through the rear end into the ring & pinion. Unfortunately I had to hire a tow truck...btw it costs $108 to get from M-ville to my house on a flatbed

My formula also has a torsen ( ) that sucks. Hopefully being an auto it will last a little longer. Although really considering how much I raced the Z28 it held on for a long time.

You going for a 9 inch/12 bolt now?

well for the time being i am going to patch up the 10 bolt so i can run PINKS this weekend cause i cant get a rearend here in time. I think i am going to have a 9 inch built. all 4 spider gears...i guess thats what their called...were stripped and one was broken in half. luckily though the ring and pinion are fine. so maybe i can have it ready by the weekend. i cant complain about my 10 bolt though. it is deffinately one of the tougher ones...ive beat the **** out of it. suprised it lasted this long.
