How to pick out a 12 bolt??? I am going to be purchasing one in the near future. I have no idea what I am going to need when it comes to a 12 bolt...
Tell me what I need...
I have a 1998 Z28 A4. I plan on spraying about a 200 shot and have a 382 All Bore. I am going to have a Vigilante 3600.
Is there any more info yall might need to help me better pick out what I need???

Really. who?
Colonel runs a 12 bolt.
12 bolt is the only option for a ABS (non TCS) only car.
Traction Control(TCS) car can use 9 inch or 12 bolt.

Re: How to pick out a 12 bolt??? Apparently you can get a Moser 9" with ABS and TCS, but the Moser 12bolt is also apparently stronger.
I dunno much about autos, but definetley get 33 spline axles. I'd say maybe a 3.73 gear? check out www.prestage.com that might help you better with gear selection.

I've heard of many instances of poor build quality by Moser, people twisting the axles on the Strange 12-bolt rears, and broken posi's left and right from both. Another thing to consider... The Eaton HD posi that Moser uses is built by Eaton as a 30 or 31 spline (I don't recall right now), but Moser modifies it to work with the 33 spline axle. That is the weakest link that I know of - a 33 spline Eaton Posi can fail under high HP (guy was running 10s).
When it comes time for me to get a 12-bolt, I'll probably take my chances with a Moser, order the 30- or 31-spline axles (not 33), get the Eaton posi w/ 4.10 gears and ABS. That should hold up well enough for me. I'm planning on running about 118-120 mph in the quarter, with 28" tires, so I should be turning around 6000-6200 RPM in 4th.

Re: How to pick out a 12 bolt??? Well, I know three deep 10 Second F-bodies running the exact same Strange 12 bolt rear that I have in my Formula. They haven't had ANY trouble.
My Strange came ready to bolt in, filled with fluid. Bolted it in and went! <img src="images/icons/wink.gif" border="0">

Re: How to pick out a 12 bolt??? My Moser was a ****** headache. failed, rebuilt, failed, shipped back to moser
axles too long, machined.
put it back together and in myself and had a whoppoing month of trouble free driving. I'll never buy one of them again. I'd get strange next time.
Though Moser fixed it and paid shipping, they can kiss my ***. **** poor quality control. Axles were too long BOTH times i got it from them. Both! I even told them about it when i sent it back!
Gears were noisy too.
I wouldnt get 33x either. 30 would be fine and less static loss The Eaton HD is the **** though.

I've got a long thread on it over at www.camaroz28.com look under user name "Chris' 396 Z

Re: How to pick out a 12 bolt??? My Moser 9" was a POS from the get go. Long story. <img src="images/icons/rolleyes.gif" border="0">
BUT, my Moser 12-bolt is awesome! Never a failure with hundreds and hundreds of launches. It's taken me into the 9s and I fully expect it to take me into the 8s in 2002.
I have the 31 spline axles with the HD Eaton. The Eaton is VERY strong and very quiet. <img src="images/icons/cool.gif" border="0">
BTW, Rob Moser himself told me that their 12-bolt for the F-body is stronger than their 9". Why? Because it's not just a reworked 12-bolt. Moser designed the housing new from the ground up. Plus, it's lighter and fits better too (doesn't make it look like you have a lift kit.)

Re: How to pick out a 12 bolt??? OK... it won't last, but ....
I ran 10.98 @ 125.83 MPH on stock tranny and stock rear axle. <img src="images/icons/grin.gif" border="0">
I've raced about every other week since March and nearly every week since I got the SC (late September).
