I am currently at 400 RWHP on my Trans Am, WS6, A4. I would like to upgade my rear end because I plan to spray 125 wet shot soon. What rear end will be best to buy that will bolt right in and I can use my UMI Torque Arm, stock Driveshaft and stock brakes? Some say Moser 9", Moser 12 bolt and Strange. I want to hear from guys who have bolted in these rear ends and how they perform. I would also like to know how hard it was to install.

if you are lowerd you have to make a little more clearance, but is not hard to do.....other than that, install was easy

the best bang for the buck will be the Strange S60 if you are gonna keep the UMI t/a. it will require a new driveshaft, but with the power you will have i definetly would not be running the stocker. if the driveshaft fails it will cost you much more to repair the damages than the new shaft will cost in the beginning... and then you still have to buy a new driveshaft. this goes for any rearend you would upgrade to. the install on the S60 will be simple... stock style bracketry and the t/a will bolt up with no clearance problems.

I wouldn't see any reason why with 400HP+ you wouldn't be ok with a 12-Bolt.. I would recommend Strange first but Moser is good as well. Both rear ends won't require any special items and all the products you have now would bolt right to it including your stock driveshaft. The S60 is a great rear end too and is what I use but could be overkill for your application.

Hope that helps a little,

About how much is a strange 12 bolt shipped?

We don't sell them direct, I suggest to try Byunspeed or Speed Inc.. both are great to deal with.

they are about 2500.00. any rearend you purchase price will depend on how you outfit it.

If your not looking at going with a "massive ammount" of power, go with the 12 bolt. I got my S60 from Byunspeed and they have unreal customer service. Lucky that you have the A4 which means you can run a A4 day in and day out without as much worry as a M6.

I have a Moser 9in, Love it. Im using a UMI T/A also, but for the A4, Id go with the 12 bolt. If your unlucky like me and seem to have to pull your axles every 6 months for studs, then the 9in is golden..got it down to 20mins now

I bolted-in a Strange 12-bolt and couldn't be happier. I'm sure the other options are great too, but I have no experience with Moser.

It was like installing a stock rearend; it just bolted straight in, no modifications necessary, even came filled with gear oil. It was a little pricey, and I had to wait for it. I got it with new backing plates installed, 4-channel, aluminum cover, and a new Strange CM driveshaft. The price with shipping was a little north of 3k. I couldn't be happier though.

Has anyone ever used amsoil transmission fluid or motor oil if so which ? I have a cam and about to install nitrous and I wanna make sure my car holds up to anything I throw at it .

I would go with the S60. Best aftermarket rear end for the buck, imo. It bolts right up like the stock rear end. Give Carl at CRP a call.

Considering the OP asked almost 9 years ago, if he hasn't decided by now, he's never going to. :p
