No track? No need to upgrade the rear..

 

As everyone has said, stick with the ten bolt for your app. It's obviously cheaper but it's also lighter (better ride and handling) and it's fairly effecient (more power to the ground and better fuel economy). The ten bolt will often survive behind an automatic tranny with much more power and traction then you have.

If you were going to upgrade I wouldn't waste my time with a B&W, I'd step straight up to a Ford 9" or 8.8" or a GM 12-bolt. This is only needed for M6 drag racers or more heavily modified A4 drag racers.

 

It still must be worth the money for the piece of mind a near indestructable 12-bolt must provide.

 

For all youse guys that are breaking your 10's what kind of driving are yo udoing at the track? Are you doing hard launches? or just regular neutral idle take offs?

 

my 10 bolt broke leaving around 1200 rpm with stock converter,catback,cai and drag radials.

5 teeth came off the ring gear.

 

i didnt break any at the track... they all broke on the street with street tires....... granted i beat the car to death at the track, but all have broke on the street... every last one sheered 2 - 3 teeth off the pinion..

 

is your car an M6?

 

Like someone mentioned earlier, just stay away from using DR's or ET streets. Auto or manual you can gernade a stock rear with just a bolt on car..if you run these tires. Of course there are some people who get lucky and do not break the rears, but there are just as many breaking them when getting great traction.

Sucks to have to pay a tow bill after launching on a stock 10 bolt and ET Streets. LOL

 

My stock 10 bolt is holding up fine with 3.73s and a TA rear girdle, I also run Nittos all the time.
Yeah its an auto.

 

Amen brother. I went with a 12-bolt Moser, 1350 series u-joints, and new 3.0" steel driveshaft. Man, is that 12 bolt burly compared to the stocker. There really is no comparison. Everything is bigger and better: posi unit, gears, axles, housing, bearings. When you see this rearend, you know it is meant for heavy duty street or racing.

About the only thing that can break now is the tranny. Hope that doesn't happen.
