If YOU think that doing all that bullshit to a 10bolt is going to save it its not. Your just going to be throwing money at something that isnt worth it. I forged mine and spend a good amount of money and time doing it And it just broke again for the 3rd time.. 1st time it was stock second time it was the new posi third time i broke moser axles chiped and destroyed my ring and pinion blew the barrings out and the eaton blew. good luck also i was hiting it with an 3500 stalled auto with about 400 n/a unlocked.

People will always try to shine a piece of **** for 1 main reason.

A new rear is a big chunk of money all at once. Its cheaper at the time to rebuild the 10-bolt & hope you made it strong enough. BUT, as stated above, its useless. If you have a auto its gonna last longer than a 6-speed.

Bottom line that most everyone with any experience in these car has to offer is DON'T waste your time & money on a 10-bolt. By the time you rebuild it a couple times you could have a 9" rear. If you plan on any drag racing upgrade the rear & ditch the pathetic excuse for a rear thats stock.

If you don't want to bite the bullet & upgrade properly, you own the wrong car & you WILL keep breaking rears. What the hell is the point in modding if your not gonna do it right & build it NOT to break.

I personally wont spend the $2500-3000 on a 12 bolt or 9". I dont drive my car that hard all of the time and the overkill would be wasted money for me. I ahve not had any issues with mine. When and or if it ever goes out I am doing some simple mods...

Welding the axle tubes
Keeping the same ratio (3.42 M6 car) gears but having them cryo'd and or mikro'd if possible.
Upgrading the diff and cryoing it as well.
Upgraded axles
T/A diff cover
1350 U joints

Then just a simple rebuild. This will keep the project under $1000 or so and should handle anything I plan on doing with the car. My biggest thing is I dont mind taking it to the track, but I am under the thinking of dont drive it liek you stole it unless you can afford for it to be down. Mine is my daily driver so I cant not have a car and dont want to spend the money on a bigger rear.

Plus the 12 bolts and 9"'s both require more power to turn them versus the 10 bolt. The main thing about the 10 bolt is the carrier size which has been stated and the use of cast materials that are just sub par.
Good luck keeping all that under $1000. Maybe with some used parts and real searchaing, and deffinetly doing the work yourself. Parts are not cheap, which is why the upgraded rears are not cheap.
Also, there are good deals on used 12 bolts every now and then. One guy is selling one now for $1800 exchange for a good 3.42 rear.

I broke my 10 bolt on my '00 V6 Camaro. It was an auto too. I had exhaust, intake hypertech and some other stuff and on shift to 2nd it went boom. ate up the spiders and cracked part of the housing. The stock 3.42's were still ok though. Go figure. My '96 Z with below mods is a M6 and hasn't destroyed it yet but i'm sure my day is coming.~Cole~

Once again what most people miss is the money equation and the use. I dont drag race my car. Heck I ahve not been to a track in 2 years right now as it is.

That is the main reason my track times are so bad. I am just not one of those people that does out to the track and expects to be able to dump the clutch at 4000rpm's to turn a good time. In the end if you expect to do that and drive home then yes I would say you would want to upgrade the rear.

My other thing is I have access to most of the parts at or near cost and can do the labor part myself.

Nothing screams abused and or drove hard more than a 9" or 12 bolt rear in a car that came with a 10 bolt to me. Plus how many of those rear ends are a true plug and play that work 100% just like stock and dont need any add ons or modification to the brake system and also work with the factory ABS system?

That is good to know. I dont like upgrading things that end up having to remove and or not work with the systems on the car. I ahve seen a couple of posts about people talking about getting rid of the ABS system due to rear end installs and was not sure.

Unless my rear shells the whole thing and nothing is salvageable I wont replace the whole thing. I am more worried about my tranny at the moment than anything else.

Bob @ EPP & several other sponsors sell direct bolt in rears that require no modification. The only reason to modify is if you pick one thats not already designed for your specific set-up or if your wanting to change some things.

I broke mine in almost stock form on street tires & I launch @ idle at the track. Of coarse when you dump it your chances are higher, but it can still break without dumpin it.

If your set in stone about rebuilding the 10-bolt then nothing we try to tell you will change your mind. I just don't understand wanting to **** away money like this.

I say if you can't afford to upgrade it, just rebuild it cheap to like stock form & drive it normal till you can afford a "real" rear. Thats what I did & I plan on a 9" within a couple years. Not just to beat on it, but for insurance for when i do. I won't ever have to worry about breakin a 9" with my future goals. Just b/c it has a aftermarket rear doesn't mean it gets beat on constantly.

Tell that to all the people who have done it, me included. On street tires and on the 1-2 shift.

Good video BTW.
