Default Rebuild or replace rear end...

I was going to post a poll but I'm guessing my limited posts keeps me restricted. Who has rebuilt their rear end using what differential, and what axels if different from stock? What use does it see? Track with slicks, track with drag radials? How many times a year does it go to the track.? Hard launches, manual, automatic, anthing else that might be pertinant to my decision to build or replace
Thanks

ah...the poll option came up after the post. Also my car is going to be in the 450 to 500 rwhp range with 3600 stall. That might help advise.

I here ya on the do it once. I should also mention I have a Moser with a tru trac in my m6 lt1. Every one knows the t-56 is brutal on drive trains. Addtionally my thought is that as far as I know only the differential, axels, and gears go bad. So why wouldn't replacing those parts with the best components possible be the better answer?

450-500rwhp.................. aftermarket rear end for sure. Don't waste a dime trying to make that crappy 10 bolt stronger.

I was in the same shoes a few months ago. I found myself planning to spend almost $800 to rebuild my 10 bolt and had to sit back and think about that. I decided to put that money into a center section and then a housing and axle package. I'm only missing the housing now which comes in a few weeks.. Although my car has been down almost 3 months, I definitely would have been kicking myself in the *** if I had spent almost half the money of a moser 9" on a 10bolt. If you need cheap rear repaired just buy a spare 10 bolt to get you by while you save for a better rear..

with the numbers you said it is not even an option to stay with a 10 bolt, you will have way more fun with the car ,and if your going to the track you will be able to get some good launches,

I make about the same power to the wheels and have the same size stall. First time to the track with a good launch my "built" 10 bolt broke... MWC 9" it is.

Your car is an automatic right? You could get away with the 10 bolt for a while. A buddy of mine was running low 7s in the 1/8th, 1.6 60fts with the stock 10 bolt and 4L60e for quite a while. Obviously if you have the cash I would get an aftermarket rear, 12 bolt will surfice for an auto.

Thumbs up Good info

This is the kind of info I need to convince me to go one way or the other. I hear allot of people saying "Just get a new rear" like its a fad. You are the first person to ever tell me that they broke a built rear end. Knowing that a built rear will break first time at the track is good info. What on the built rear broke?

The 02 Z28 is a 4l60e.

The spider gears in the diff exploded, but I gotta give it a little credit. The same setup has seen a lot of 1.5 60s with less power and a lot of street miles. The extra power just killed it.

Spending money on the 10 bolt is a poor decision.
