Need help picking rear end!!

[Pro86tourn]

I know this has been discussed 100x but I am looking for a drop in solution (most cost effective) to work in my monte carlo ss. The car has a stock 7.5 posi with new axels, but I am looking to put a stout rear behind my built 6.0LS/TKO600. I have heard mixed reviews of the quick performance rear.

I bought Ride tech coil overs so i wont be needing spring perches, and UMI upper/lower arms... I would like to use the new suspension ive purchased to bolt the new rear in. The car is a pro-touring style build and I want the car to handle well for the road but have the ability to do auto x/road course the odd time.

I know people will say 8.5 but they are creeping up in costs too... might be better to just spend the extra cash on a 9''

Let me know your thoughts!

IMO for the cost of an 8.5 Gbody I'd just spring for a 12 bolt or 9 inch built by a reputable company. Leave the 8.5s to the 442/SS guys.

then it's just see which is priced right. 9s are nice if you change gear ratios. 12 bolts look like they belong. That would be my criteria

8.5 would still be most cost effective BUT, going with a nice 9" opens up a lot of different options for brakes center sections and carriers.

Agree w/ Pontiac - order a 12 or 9 the way you want it with the ends axles and splines to fit your needs and its new. I prefer the 9 - readily available and reasonable.

which manufacturers would you guys recommend for best success?

Don't sleep on the Strange S60.

Don't sleep on the Strange S60.

Why, does it snore?

What do you mean?

Slang for "don't eliminate it as a possibility" Get up to speed, old man!
Of course, there's the Exploder 8.8, too, but I don't think it will work with the UMI arms/coilover combo.....

I have been looking into the Moser 12 bolt

I've had good luck with quick performance.
