What are you doing / have for a rear end. We are ready for alot of rear end work and would like to put rear discs on 9 inch end caps with a welded up 8.8. What are you using? Thanks. Trying to find the best path with the least $$$. I find rear ends are $700 - $7000.

I have the 8.8 with the high end Mosier 31 spline axles, c-clip eliminators, long hardened wheel studs, T/A diff cover. I have seen many 8.8's with this similar combo running deep into the 8's with no problems / breakage.
I know some people that insist upon welding the axle tubes but I have been told by a very good fab guy this is not a good thing to do because it degenerates the metals in the tubes / diff because you have to get it very hot to weld together. Then later on it could crack.
The other thing to make sure to do is weld up the rear sub-floor, upper control arms, and make sure rear-end geometry is all good so that the car is loading properly. This will eliminate unnecessary stress on the rear.
I am still debating rear disc brakes, I think very good fronts are a much better decision than spending the coin on rear discs. At least for drag racing.
Best of luck on your end.

Fronts get useless @ 150+ and they make the rear wave. With rear discs, like the chute - rear brake application pulls the car to a stop straight. The choice is race brakes ($420) or dual caliper street breaks ($600). I was talking to a guy who runs 7.70 and he uses teh street because he has a turbo and needs to load the motor, but he thinks I can get away with race brakes.
Rear end I think are the hardest things to build since there are 100 directions you can go. Thanks for your input.

Scott, get the rear discs.. Trust me on this...
Just went from drum to disc right before the 8.65 pass and glad that I did..
You're going to probably make some serious top end with that thing and you'll want to be able to stop just as well...

rear disks=less rotating mass=faster
