So i am on the final puzzle piece for my M6 02 Trans Am. So i have a a Procharged forged 370 that hopefully will be pushing around 700Hp to the wheels. of course i originally want a 9 inch, wavetrac ect etc..4000$+. But i found a guy wanting to sell his strange 12 bolt. This car will be 90% street car...maybe at the drag track twice a year. Anyway i can get a good deal on this. heres the breakdown:: Thanks guys!
12 bolt F-Body housing with mounts - H12FME
33 spline Alloy axle package

Is this the one that was posted on here yesterday? Honestly a 700 rwhp M6 fbody with a 12 bolt is not a great move IMO

Really the answer to this question can only come from you being honest with yourself. I've seen 12 bolts hold up for people with good power and an M6 as long as the launches aren't crazy. You say 90% street car, but what do you want it to be able to do the other 10% of the time? What's the rest of your drivetrain setup (clutch, trans, driveshaft)?

I will say this; the Strange 12 bolt is the best 12 bolt out there imo, and it is setup nicely based on what you described. If the deal is good enough, it may be worth consideration. Just keep in mind that at that power level a hard launch will likely make it noisier, and at some point it can still fail. I lost one with a lot less power on a 5000RPM M6 launch on E.T. Streets. On the flip side, however, I watched one a buddy had last for 10 years of abuse with more power.

Clutch material will play a part, and so will driving style

The clutch is the Monster LT1-SC. Honestly my gut tells me to hold out for a 9". Thanks for the replys..

plus...i have heard great things about the wavetrac..plus with all my research it seems a 3.5 gear would be better..unless i did step up to a decent size drag radial. Of course a drag radial and that 12 bolt may not play too well together for long....

Thats a great rearend for a street car. You wont break it. You wanna do slicks and track it regularly with clutch drops and the whole 9 yards, 9 inch all the way.

If it's a race car running 1/4 and 1/8 miles passes all the time at different events then I could see going with a 9 inch for the ease of swapping out gears. I really liked the MWC Fab 9 and that would be my direction if my S60 ever grenades on me.

thanks guys i value your opinions

If that's the one that's currently being listed on here, I think he is asking $1800 for it. For that price id do it if you don't plan on launching the snot out of the car on slicks a lot

Get the 12 bolt, add a clutch buffer.

Without a clutch buffer, you will need an S60 or built 9" and your 60's will suck.

Add a clutch buffer, launching 700rwhp at the strip with a 12 bolt/radials won't be an issue.

actually this axle is for sale on craigslist for 2300$ what i dont like is the milage is unknown but he said before he bought it everything was "tight". Not really sure how far to read into that. He decided to keep his current axle. If i can get him down on the price and have someone more knowledgeable than myself to look at it with me...i may do it. Unfortunately it is a 4 hour round trip for me to get it. thanks for your input Gents!

They're a solid rear end. If you're able to get it even cheaper it's hard to say no IMO

I would question why a Strange anything has a Yukon posi traction in it. If that is the case then it has already taken out one ring and pinion plus the differential Strange uses. Which I can see that from a 12-bolt depending on how it was used.

I would be concerned that the housing itself is no longer straight.

^^^ Like he said, thats a STRANGE Engineering 12 bolt with strange internals. I would be concerned as well.
For a little more than $2300, you can get yourself a brand new S60 w/a spool. But i don't think you'd want to daily drive it.

Thanks guys. I think i am going to steer clear. I would rather just go a few 100 more and buy new. Thanks again!

A 12 bolt can be bought as a housing and axle package. Doesnt mean a ring and pinion has been "removed"

True, however with the thousands of Strange 12-bolts, S60, and even Moser stamped nine inches that we have sold we have never sold one empty 12-Bolt or S60 and a handful of Moser stamped nine inches.

Consumers especially the F-Body owners generally purchase complete ready to bolt in packages. We barely sell empty housings with our fabricated nine inch. Heck out of the 100 plus MWC fabricated nine inches last year sold 95% of them was completely assembled.

I did just learn at some point Strange did switch to Yukon for their 33spl. It is in their new catalog but wasn't in my old one and not completely sure when they made the transition as I do not stay to up to date on the 12-Bolt for the F-body as we would rather not sell them. With that said we stopped selling Yukon clutch posi in the fabricated nine inches for a reason then add that to a 12-bolt with known issues of not surviving in a F-body application and I would stay clear.

The Strange S60 will always be your best bang for the buck, we never had any issues with them and they are bullet proof, most 12-Bolt consumers from the past will tell you differently about their 12-Bolt purchase. Downfall of the S60 is weight and gear selections and that is why the Midwest Chassis fabricated nine inch is so popular.
