Rear for AutoX and RR

Rear for AutoX and RR
Well my rear has been making some ticking sounds and now its howling like a bearing has gone bad. I already replaced RH axle bearing and seal and that made it alot quieter but its still making noise. My goals for this car are like 400whp and the car will be only ever see RR or autox. I dont drag race, it will never have DR or slicks on it. Am i ok rebuilding stock rear with a beefier gear set and upgraded axles? I know people are going to say to put a 12 bolt in it but i seriously dont think i need it. I also want to keep my weight down as much as possible. Sorry if this has been discussed but i havent really seen anyone build a rear towards autox or rr.
thanks

i am wondering this same question as to what rear end is the best for auto x, but i want my car to be a dual purpose car and be a 11.5 bracket car as well. What i have read and heard so far is that 9" is bad for abs and tcs, so i am trying to read up on 12bolts.

We have no issue with 3ch or 4ch on our rear end builds and we have a lot of customers out there that only auto-x or road race their vehicle and they take advantage of our Watts link set up. Not to mention, if you are concerned about weight we can get one of our rear ends under the stock 10-bolts weight.

Yes one of our housing are within your limits and will work well for what you are doing. Like stated we have many users out there that use our rear ends for many different reasons. Starting from spirited daily driving, moderate weekend drag racing, the weekend auto-x, road race cars, and heavy hitting drag cars.
The goal of all of them was to get a rear end under their vehicle to eliminate the possible chance of breaking the 10-bolt or any other inferior after market housing. The fact that we are not limited by certain companies parts help us put together a combination that will get you what you want from a rear end purchase.
We also go take the needed further steps in our rear end builds by putting on the brake line tabs, e-brake cable brackets, and we ask what kind of exhaust you have on the vehicle to get you the proper cross member. We even go as far as asking what kind of shock you are running because we predrill the holes for you so you do not have to do it yourself.

well thanks for your help guys, so if im going to replace my rear what kind of setup would you give, ie what type of center and what not, also keeping in mind i would like the weight to be as low as possible. and this will not be a drag car. also since my car is not a daily driver so normal wear and tear isnt an issue do you guys have anything to strengthen the stock rear end, i mean if i do break it it wont stop me from working and what not.

Seems the Wavetrac would be a good autoX/RR diff as well as handle abuse for occasional drag strip use. Only issue I see is the 35 spline axles needed for the Wavetrac will not accept a tappered axle bearing, which I'm assuming you would want for severe side loading.

Really....thats awsome!
Just sent an E-mail to Moser asking to confirm a blurb I read about a 31 spline Wavetrac in the works for a 9in. cause I figured the tapered bearings ony worked on 28-31 spline axles.
Whats the weight difference between a 31 and 35 spline axle?

Just got confirmation from Moser that they will start production after the SEMA show, and expect to start shipping in 4-5 weeks.
I guess the question now.... is the weight savings worth the exchange in strength.
