which one can take more power and torque? which one shall i go with? please list reasons if you choose to go with 9" or 12 bolt.

thanks.

9" will hold more power, they are heavier, you cannot retain abs, unless you have abs and tcs.
12-bolt should be fine

I had a Moser 12-bolt, just switched to a 9". My biggest gripe was that I couldn't run a spool w/ a 3-series carrier. No problems w/ a 35-spline 9" running 3.50s and a spool. 9" will hold a lot more power and can be lightened quite a bit (aluminum center section, lightened gears, drilled and star flanged axles, etc).

There's always Billingsley's 9" setup which is light as hell.

looks like the 9" is better than the 12 bolt except for the ABS problem. can't i fit ABS to the 9" in any way?

btw 777, what is tcs?

thanks.

TCS is the same as ur ASR...its traction control. correct me if i am mistaken, but i believe that i have seen some 9" rears out ther now that do have ABS.

If you have a 4-channel rear (both traction control and abs) then you can run a 9" with abs...otherwise you are out of luck

With a M6 a 9" with Detroit Soft Locker is bullet proof. I have no problem dumping the clutch at 4,000 rpm's with Mickey Thomson Drag Radials. If you have a strip only car think spool.

That's not saying much with what some people do. Dump clutch at 6500 on full slicks... granted they are running a spool though.
