Still undecided!!! Opinions please!
I've been reading on and on the past few days, however, still undecided on what rearend to get.
Here's a quick run down on the car. Its a full bolt-on LS1, with full UMI suspension and double adj. QA1's up front; only the stock rear springs remain (heater hose mod). It also has a FLT Level 4 trans w/ 4k Circle D converter.
A few weeks ago, I broke the 10 bolt and replaced it with another stock 10 bolt for the meantime, just to get the car running again. I've been reading on both 12 bolts and 9" rearends, but still undecided. Some have told me just to get a 12 bolt as I'm auto, but for the same price I might as well get a 9". My car does have ABS/TCS but I will be getting an ABS delete kit and not concerned with TCS. My car does get driven every now and then on the street and highway, but a spool is preferred. My goals are to get a 11.5X on bolt-ons and eventually a 10.99 on H/C/I on a stock shortblock. The car's weight is approximately 3250 as it sits on stock wheels. Any input is appreciated.

i just got rid of my 12 bolt for a MWC fab9"......
the fab 9" is lighter than my 12 bolt & if i remember right the 9" weighs about the same as a 10 bolt.....
i am a m6 & every time you go to the track with a 12 bolt it seems to get louder than the time before....
i would do it once & do the 9",it is nice to finally have a quite rear.....
good luck!

Strange 12 bolt.....I believe its a better design then the Moser unit at an equal price from a better company. For 10.99s you do not need a nine inch rear end by any means.

i have seen 10 bolts do 10s.....i ran low 11s on mine,11.08 with a 1.48 60'
but by the time you spend the money on a 12 bolt....
the weight difference,the noise they make & the labor involved.....
i would do a 9" for not that much more money & enjoy the quite & strength with a lighter weight.
but thats just me......
good luck.....

The problem is a good 9" doesn't cost that much more than a good 12 bolt. I'd prefer the 9" over a 12 bolt any day due to the ease of gear install, and the wealth of aftermarket for them. If the 12 bolt were much cheaper, it would definitely have a larger market.

I agree, my Moser 9 inch prices are nearly identical to my Moser 12 bolt prices. Bob

I can only relate my experience with a Strange 12-bolt, and I've never had a 9" (I might like it more if I did, but who knows). The Strange was perfect for me because it was so easy to install, like stock for stock, and everything works like stock with no issues (TCS, ABS, etc.). I must be really lucky because my 12-bolt is quiet, but then again I've only hammered it a few times on the street. The extra weight I've found to be an advantage because it softened the harshness of my lowering springs and stiff shocks, and an added bonus is extra traction in the winter.
Overall I couldn't be more pleased, but I did spend a lot for it along with a new chrome moly driveshaft, around 3600 including shipping. FWIW.

Strange 12 bolts aren't more quiet because of luck IMO. Everyone gives 12 bolts a bad rap for being noisy, however, you don't see many complaints about Strange 12 bolts. Wanna guess what rear end I bought??

There are plenty of people on here who went with Strange 12 bolts who ended up with gear noise, you can search threads on here to find them. Manual transmissions are normally what brings out the gear noise with 12 bolts. Bob

I am very happy with my spooled-Strange S60, although, it has yet to be track tested (very soon though). It was a budget decision for me.

...yep, a little more weight, but what better place to have a little more weight than over the rear tires!

I appreciate all the information guys! I've decided to go with a 9" rearend as plans do change and have that peace of mind. I do agree with a slight extra weight over the rear tires. Thanks Bob and MWC, I'll be giving you guys a call pretty soon within the next couple of weeks and figure out my options!

Oh and my strange 12 bolt started making noise on the 2nd day I had it. Its annoying with the windows up but tolerable otherwise and occurs at certain speeds for me. Still a little dissapointed when you drop nearly 3 grand on it and it whines, but I'll take some whine if it stays together.

Good choice. I bought a strange 12 bolt from mwc back before Eric started producing his fabbed 9"s. I have a car similar to your plus H/C and a bit more weight. I am not worried at all about breaking this rear. However one of these fabbed 9's is a better unit all around and cost almost the same as the 12 bolt. If I had to do it again I would get the 9", no such thing as overkill.
