Of course, your answers would be based on the same things, i.e., gear size installed ... DR's versus slicks vs street tires.
Or did you guys/gals go an entirely different route than the 12-bolt rear.

My B/F twisted axle splines and even broke a Moser axle with his 12 bolt when it was a 6 speed on slicks.

Now, that's an idea .... I'm not sure if I would miss the ABS ... the cost sure would be better and I could probably handle the impact. If they're gonna' have my car for another month, maybe this is the time for the rearend to go in and be done with it. I just can't handle the cost of a 12-bolt after $13,500 I just spent on the motor and supporting mods ... plus the $3,000+ I'm having to spend on a racebuilt tranny. DAMN! These cars are expensive ... LOL!
I really liked the 9" I saw on NEXT's car. Looks like a horizontal radio tower section. Think a 9" would be Ok for a daily driver? ... aren't they about the same weight as a 12-bolt?
Maybe sell the current rearend for $400-$500. It has a brand new HD Eaton posi, nice MAC girdle cover, and a brand new 3.73 GM OE factory ring gear and pinion setup ... installed only about 500 miles ago.

Mine's sold for $650 ... to a guy in Cali. I decided to go with the Strange on the recommendation of my builder. The strange has the torque arm mounted with straight-through bolts ... went with the 33 spline axles and 3.73's, so, it should handle anything I can throw at it.
One deciding factor ws there is only a $200 cost difference with the 12-bolt versus the 9" ... being all things equal ... that is, both rearends max'd out with everything you can do to one. I guess the labor probably accounted for a big chunk of the money ... 12-bolt is assembled and the 9" ships in seperate packages.
I did ask Eric and he said he took the advice of an old popular racer who told him to build like he was going 8's, which he has done. Mine's a street/strip car, and driveability are important to me. Thnaks for the advice Claire and I'm nearly certain I'll be at BMP with you folks.
I'll send you a money order before the first. If I can't make it for some weird reason, I don't expect a refund. TTYL.

I have Moser 12 with 4.30 gears. No problems after 6K miles and several passes on the strip. It is loud at hwy speeds but who cares.... its to be expected.

love the moser, but the noise comes from the gears. I am going to install some Yucon gears and see if they are quiter. only because someone has to find out for those who want a fast quite ride. Btw I am lightly modded and staying with heavy hitters, I like to think its that I have adapted to the car very well.

Moser 12-bolt. 4.11 gears. Girdle-cover. 33 spline axles. Eaton HD posi.
Nice and quiet as received from Moser. Adding the backing plates myself was a cinche and allowed me to Por-15 them before mounting. Here's my small beefs:
1) spring pockets are too level. For our cars that put the rear spring at an incline, which gets even more angled under compression, I would have hoped for spriung seats with about 20 degrees rearward incline.
2) LCA brackets are stock location (actually ~1/8" lower due to thicker axle tubes). For a modest amount of research they could have easily made the stock brackets extended down with alternate mounting holes. No need for LCA brackets woudl have been a nice bonus and weight loss IMO.
3) PHR is in stock location. Same deal as above... with a better brace design they could have included a 2 to 4" drop on the PHR for the corner carvers that want to play with the roll center. Granted this is a small niche market... but the option would have been nice.
4) No Backing plate option. I didn't need it, but it would have been nice... and it's probably cost them a few sales in the past I'd bet.
5) Torque Arm uses 4 bolts. Would have been nice to re-use the stock pass-through bolts for a torque arm mount. Granted, the 4 bolts used can be replaced much easier than the 2 pass-through ones, and may even be stronger... but the appeal of a stock mounting system is attractive.
6) No Sway Bar Mounts. contrary to their instructions, just using a 3" muffler clamp will not work with a stock rear sway bar. I needed at least 1" drop on the axle bushings to make it fit around the aluminum girdle/cover. Spohns brackets are a) pricey, and b) notched to fit. The BMR ones are 2.75" or 3.25"... no one seems to make a true 3" bracket set... I ordered 2.75" ones and used a 3" hole saw to cut them out to size. I still havn't welded them on, but using Grade 8 U-bolts elliminated that need anyway (had to notch the holes a bit to space them appart enough for the 3" u-bolts).
7) I specifically ordered a 3-series carrier with 4.11 gears... but the build sheet shows they went with a 4-series carrier instead. The idea was to shave some pounds off the system by using the narrow rings... but apparently the 33-spline Eaton doesn't come in 3-series, or they figured I didn't know what I was doing. Either way I would have appreciated a call.
8) Solid Pinion Bearing Spacer wasn't available. Strange has a nice unit I ordered and have ready for the next rebuild... but Moser claims it wasn't nessesary.
All minor issues really, nothing I couldn't get past on my own, but those were the things that irked me for a "fully loaded" $2300 12-bolt.

I want to get A 12-bolt now that I messed up my rear by slamming it into curb at 55-60 mph yesterday. i hope my frame aint bent that will suck if it is. I wonder if i can tell the shop what rear end i want i dont want a new 10 bolt i would rather pay the dif and get a 12 bolt. and my rims got cunks missing out of them but they still held air. so I want new rims of my choice and a 12 bolt i wonder if the insurance would have a prob with this has anyone done this i would be willing to pay the difference in prices. Just wondering. I still cant belive that I crashed i feel like its a bad dream i will wake up and my car will be fine. thank god I am fine because it is a lot harder to find parts for me than it is my car .

Sorry about your bad luck 01formula. You'll get beyond this. I don't see why they couldn't put the rearend of your choice in. The insurance company sends the shop money and the shop buys the parts. Just tell 'em you want a different rearend and pay the difference. Hang in there!
Jeb, I just ordered a Strange 12-bolt from Billingsley. I hope it doesn't take as long as you've been waiting, but if parts are backordered it probably will. I can't wait, too, to get this badboy installed. I'm psyched about 4.10s.
