Default 10 Bolt Question

Ok I know most people agree the 10 bolt is junk and once it breaks it should be scrapped. My car has stock suspention besides Lakewood LCA's. I have a bad wheel hop problem and am only getting 1.9 60' times with 26X11.5 ET Street's. I know most everyone will say to but a 12 bolt or 9" but I don't have $2K for that now. I am going to buy shocks, a torque arm and drag launch springs. My 10 bolt now has either a broken ring and pinion (Motive 4.10) or my posi exploded (bad popping in rear end after 12.5 et pass). I already have Moser c-clip axles. My question is if I replace the ring and pinion or posi or both, inistall a good diff cover and address the suspention what is going to break on the 10 bolt? Is there some part that no matter what is the weak link? I know wheel hop is the enemy and a 10 bolt will never be a 12 bolt or 9" but with the wheel hop addressed what is the life expectancy of an after market built 10 bolt? Help from someone who's been in my shoes is greatly appreciated.

P.S. Who will be the first to tell me not to waste money on a 10 bolt and to let the car sit untill I can buy a 12 bolt! I know this is probably what I should do, but I also know there are a few 11 second M6 10 bolts out there!

Oy. This has been discussed ad naseum. The issue with the 10 bolt is that you will always be limited by size. It doesn't matter if you replace the ring and pinion, they are still tiny, still prone to breakage (probably more so if you upgrade everything else). It's a nice thought to upgrade a few things here and there but the reality is they will most likely continue to break in a cycle. So $200 here, $200 there, and then a year later you're like, ****, should have just upgraded the rear. Especially with a M6 and drag radials, you are just asking for it.

If I were you I would pick up a used 10 bolt as a short term fix ($200-$400) and start saving for a 12 bolt. If you can afford a 355 with all sorts of goodies and that purdy hood you got in your avatar, you can start saving for a better rear end (most prefer a 9" anyway in the case of an M6).

But what do I know, I've been there done that and raced more than a few M6's down the track. I prefer to 'set it and forget it' (i.e. save up the cash and upgrade to a rear) then piddle around with things that "might" work.

Not this again
According to your specs and driving style you are going to continue to blow up ten bolts, just deal with it or save some dough for something bigger.

right on keliente, after i spent all the money on upping the hp, i soon shattered the rear grabbing 2nd gear on the track......i would have done things differently if i had to do it over again.....my theory now is, build the car for the motor, not the motor for the car...

put the $750 worth of suspension parts towards a rear, and you'll still be better off

a common problem is actually bowing the whole rear housing which just creates more problems...I understand not having 2k laying around...in the last 5 weeks I broken 3 ten bolts but I had extra parts I'd been saving up so it was not too big of a deal but I'm ordering a 9" tomorrow.

Theres not one set weak point for examble my posi blowing up also took out my gears...so theres no way to know. Best of luck making yours live as long as you can man!

Still not a bad idea to do what keliente said and buy a used 10 bolt (if you can find one cheap) then u can still use your car and you'll always have a working spare down the road.
