My car is a daily driver, I might take it to the strip a couple times after I get a new rear end but no real big plans on it. I just know that eventually the 10bolt is going to break so I am starting to save for a new rear end.
So for a daily driver, 9" or 12bolt?
Also prices would be nice.

just to start on strength. the 9 inch is stronger for atleast 2 reasons....3rd pinion bearing and larger ring gear diameter.

either will be fine, it will come down to price. Everyone gets different prices so do you reaserch.

Strange 12 bolt is what I would say..The 9in is heavy, (added weight slows a car down) But they are very strong. If its a Daily Driver a 12 bolt will be more than enough.

But whatever you choose..go Strange!

Its what I have and a lot of guys will tell you they are A LOT better. Iv had both Moser and Strange. The Strange just Blows Moser out of the Water IMO as far as Quality, they send you all the right parts to pit in..

For most A4 cars, a good 12 bolt will be plenty strong for their application, especially a daily driver.

i'd have to say 9" being you have a 6spd. who cares what a rear end weighs unless you have a drag only car and care about every last tenth.

True, but on the street, the amount of traction (particularly from a dig) isn't anywhere near as potent as the VHT/prep surfaces at a track. Basically, the rear end in a "daily driver" won't likely see the kind of massive abuse that it would see at the track with a 1.5 60ft, for example.

whats the weight difference between a 9" and 12 bolt

nothing worth crying over.... i would go with the 9" . much stronger not much of a price difference either.

I vote 9"... do it once, do it right. Although a 12-Bolt isn't by any means a bad rear. I'd just feel safer with the 9"

The only other 2 things I'd think about is "weight" like mentioned above, and the amount of power lost between one rear end compared to another. Weigh what your willing to lose through the drivetrain powerwise...

shoot get a "parts specific" Fab 9 inch and be at the same weight as a 10 bolt with all the strength. 9 inch vote here, You can buy a axle housing package and build a 3rd member, or go crazy to a Fab style. Price range $1500 to $4000. Pick your poison.
