Best Way To Build A Decent Rearend Without A Change Out?
What Is The Best Componets To Change Out In A 96 Ws6 Rear So It Won't Blow Up Behind A Lt1 That Is Putting Down About 400hp At The Wheels Behind A 6 Speed Spec 4 Clutch And 410 Gears? Would Rather Not Change The Rear End Maybe A Auburn Differential Or ? Any Help Would Be Appreciated

No way will a GM 7.5" rear hold that kinda power with any resemblence of traction and a 6 speed. There is a good reason that many people switch to the 12 bolt/9 inch setup.

Don't even try it. It's not worth it. You WILL end up wasting your money and regret it. Get a 12 bolt.
I have a 4.10 rear with an Auburn POSI, new axles and a number of other things and I'm putting an M6 with a Spec Stage III. Needless to say the rear will come out pretty soon after as soon as I can afford a 12 bolt.

While we are on the subject, why is it that some people say the 9-inch isn't good for a daily driver car? What're the pluses and minuses of a 12-bolt compared to a 9 inch, in general?

I've never heard people say the 9 inch isn't streetable. A lot of people shy away from them though because they require you to either delete your ABS or build your own ABS setup, if its a 3 channel ABS car.

Actually, come to think of it, it was Rich who said that he wouldn't run a 9-inch on a daily driver - and what exactly is 3 channel ABS?? I have ASR and all that nonsense, does that mean having a 9 inch would be a pain in the *** for me?

A 9" is ~30lbs heavier than a 12-bolt and it has an additional ~3% power loss due to a less efficient design. A wider choice of limited slip diffs are also available for the 12-bolt. If you have a spare center section around it is very easy to change rear end ratios in a 9", but that is big so what for 99% of us. I change engines a lot more often than I change rear end ratios!

I agree that the 10 bolt rear won,t last, it will only take about 7 to 10 5500 RPM clutch drops to end its life.
Had a guy here in KC do it intentionally cause he already had a 12 bolt to put in and wanted to see just how long the 10 bolt would last.......6 5500 RPM side steps later it went BOOM.

Re: Best Way To Build A Decent Rearend Without A Change Out?
i'm glad I have an auto in my car.. 3 seasons and everything under the diff cover is bone stock and yet to brake. I know it's a ticking time bomb in a 10.9x car though. I hope i can afford a 12bolt one of these days.
