I have had both a Moser and Strange 12 bolt rearend in our quicker 9 second Camaro. They both were very loud pretty much from day one. Now I'm about to pull the trigger on a solid rearend for my wife's NA low 11 second daily driver/bracket 2000 Camaro SS. It is a 130K mile A4 with the original 3.23 10 bolt. We drive as much as 5 hours one way to race at various Texas Dragstrips and I need a solid quiet rearend to keep the car dependable. The only reason the stock 10 bolt has lasted this long is because we run a soft hitting CircleD 4000 stall, LCA brackets and a 28" tall drag slick. The tire and converter absorb most of the shock and the LCAs prevent wheel hop. It'll hook pretty much anywhere pulling 1.54-1.58 60fts.

I already have a BMR TA with the relocation cross member so I've narrowed my choices down to a Strange S60 and a 9" with 3.7X gears. I don't have a cage in the car so I've already had to detune the car to stay legal (lowered shift points, timing, etc) so if the car slows down due to added weight that's fine. I also have an extra set of backing plates available.

So for those who have been there and done that and if you had a chance to do it over again, which would you choose? I've heard of issues with TA mount hitting the floorboard tunnel and having to modify the TA bracket. Either of these rearends will be over-kill for our power level so durability isn't an issue here. We won't need to swap gears sets in this car ever.

So which route would you choose?

Areas of concern and requirements:

Quiet operation
Simple install
Need LCA brackets
Stock style sway bar mounts needed
No ABS/TCS needed
3.7X gears
Tru-Trac is a must
New 3.5" driveshaft will be part of the order regardless
I can wait 4-6 weeks (not 2 months)
Of course price is of concern and have a feel for appx cost

The Moser fabricated nine inch is what I went with on my '99 Z28.

The price of the fabbed rear ends looks good when you figure in that they include a torque arm and tranny reloc bracket, but if you already have the torque arm and reloc bracket the regular 9" or s60 starts looking better imo. Depends if you want to keep your old torque arm or sell it and use the one that comes with the fabbed rears.

with what you have for the car and the issues surrounding the other rearends, the S60 is gonna be the best bang for the buck and an easy bolt-in with all the bracketry included. there will be no torque arm bolts coming loose, tunnel clearance issues, missing bracketry or clips. the S60 will also come with a 35 spline axle and Truetrac diff as standard features. PM or call us for the best deals on any rearend for your f-body car.

I don't know if it was implied or not, but there will be no torque arm bolts coming loose, or tunnel clearance issues with the Moser (fabricated rear) M9. The Moser fabricated rear's torque arm was designed to follow the f body tunnel contours. Bob

James, go with the S60. how do I know this, haha. I don't, just a wild guess. I know the 9" is strong, but they just don't belong in a GM car.

It does sound like the Strange S60 would be your best choice. We are direct with Strange and Moser so it isn't like we are telling you to buy one or the other based off what we can only offer you either, if that was the case we would be trying to sell you on one of our housings, which is never over kill for any vehicle but makes sense to go with the Strange S60 based off the fact you already have a torque arm.

So what's a complete Moser set up cost vs. the complete S-60? Or just tell me how much more or less....

My Moser prices that have free shipping can be found at the above link. I doubt you'll find a better price for a Moser rear end, but the S-60 will cost you less. Bob

Option to option and dollar to dollar the S-60 is the better choice for sure.

I think the 9" would be a better choice IF the torque arm was plug and play like the S-60. Somebody should wake up to this

My reason for this way of thinking is the 9" is so easy to set up. Ratio changes in a Dana 60 are worse than the dentist chair! And after market parts for a 9" are everywhere. Gears, carriers, and so on.

I say run a 3.25 gear and tune the engine for max power,the tall gear will save you gas ,lower RPMS on the motor on the long drives to the track.run the tallest gear you can the way your car performs.how do you like your 4000 converter?I'm about to buy a CIR-D soon and would like your 60s ft.

Both are an excellent choice, but my opinion would be to go with an M9 with a Detroit Locker. The M9 compared to the modern 12 bolts is very quiet and problem free. I would go with a 4.10 gear though and just bring the stall down. In the case of bracket racing with it you'd be much better off with a bit more gear since you run such a tall tire with the idea that a slightly tighter converter and more gear will help keep the trans temps down. I'm sure you've placed well with the car and there are times in bracket racing where you will pretty much be hot lapping the car so you understand what I mean.

I like the 9", but which ever you go with I suggest a solid pionion sleeve NOT a crush sleeve as I beleive the solid will hold the correct setting, if set up rite.
were you running as crush sleeve or solid on the rears which you begain having noise in a short time ?
Just asking, Johnny

I am sure theey were standard crush sleeves since they were pre-assembled and I did not specify. They were also both 12 bolt rearends which are known for noise issues in TA style applications.

I had a Strange 12 bolt, and a Moser 9" in my 2001 M6 Z/28. Went through 3 sets of gears with the 12 bolt and it got loud every time. Got sick of it and bought a Moser 9" with 35 spline axles, 4.57's, and a Detroit locker. Beat the hell out of that rear and it was as quiet when I sold the car as the day it was installed. We did have to do a bit of clearancing in the tunnel area, but the BMR tranny mount torque arm that was used with the 12 bolt worked fine with the 9". Sure the locker popped and banged going around tight turns, but going straight on the highway it was quiet. I would get the standard Moser 9", you don't need anything stronger.
