John and all Sponsors... Please just FYI: I understand and respect the process that LS1Tech is on, Scott didnt approach me on this I approached him (As you can see he was recommended to me as a technical expert to give me advice).

I have also called and received quotes from 5 different sponsors on this purchase... some where in their prices and some were real good! I am simply a consumer doing research.

More importantly I am trying to get all of my facts in line and then share them with the other members on this board who may have a similar application.

Currently this is what I am looking at (prices vary depending on sponsor):

Moser 9" setup with 4Ch ABS

I am currently doing research between the True-trac instead of a Detroit Locker because I have an M6 (PLEASE ALL OPINIONS WELCOME ON THIS!!!)

I am also trying to determine the need or advantage on having the relocation brackets welded on (INPUT WELCOME HERE AS WELL PLEASE!!)

What spline should I use? 31? 35? Advice with Advantage and Disadvantage is appreciated!!

I have not had anyone that says I need to have the TQ arm replaced so I think I may pass on that for now...

I have decided to go with the 9" vs 12Bolt because the TONS of feedback about the loud rear-end in the 12Bolts...

I already have the Trailing Arms and Panhard bar... BTW thanks for the input on the necessary Sway Bar relocation!

I intend to run a 3:50 gear ratio because I am doing a boosted application..

Scott and other members have been very helpful with advice!!! Thanks guys!!

Oh and to answer the other question... I am hoping to put down 500RWHP and apx 600Lbs of TQ (I am not sure how accurate my estimate is)


Thanks again all!!!

 

Oh and I just answered one of my own questions: This product is a must for lowered vehicles to correct your suspension geometry. Lowering your vehicle alters the LCA angle putting the rear of the LCA higher than the front of the LCA, this causes massive wheel hop and traction loss.

NON-LOWERED vehicles will also see a dramatic increase in traction by lowering the rearward angle of the LCA with our relocation brackets. The lower mount holes are placed in the arc pattern of the OEM length LCA. Therefore allowing a non-lowered F-Body to drop the rear LCA angle and NOT require a longer than OEM LCA. All geometry is correctly maintained. The anti-squat performance is providing most users with a full .10 or better 60' reduction!

Slowpoke.... I think 600-650 Pounds of TQ? (I think) And you think I may need a TQ arm? At what HP or TQ do I need that? Any reccomendations of brand or design?

 

May be i can add a little. The relocation brackets i had welded on were from Sphon Nice design and much better quality the some of the other crap i have purched to save a little. I feel the are a good investment are they needed NO. But with the housing sitting on the bench empty it is sure easy to add them now then later when they are on the car. I feel the car hits and bites a little harder. (opinion)

I went with the True Track like Scott recomended and i am 100% pleased i will never go back to posi (clutch packs) it feels great.

As for spline count get what you need spline count has to do with HP TQ and weight of the car. If memorey is with me here i think 31 spline will hold 700hp (correct me if i am wrong) so why add all that rotating weignt it is over kill. It is all your decision though if you plan on having a 8 sec drag car then go for it now.

Good lock with your ride you will love the 9"

 

PSJohn PM sent, well at least I'm not logged on as "Scott @ Driveline Solutions."

 

longrange4u, I drive a 31 spline detroit locker and have an M6 and it does not bother me at all. With that much horsepower and an M6 it would seem logical to skip out on the posi all together because while the Tru Trac does look promising it is not going to be nearly as strong as a locker. Get the 31 splines because parts are readily available for the 31 spline and no need for excess rotating mass if it is not needed.

My apologies on my post as well, hopefully Scott will become a sponsor on this board so he won't have to do any more "pimping."

 

I've got the 31 spline Detroit soft locker, which is the locker for 31 spline axles. It pops and clanks from time to time , but I will say when you do a high RPM clutch dump you don't have to worry about whether you're going to get another run in. I think the True trac is fine for an A4, M6 I don't know.

 

where can i get a center section with gears i would perfer aluminum.

 

Strange. Aluminum case and/or pinion support is drag racing only.

 

Na, thats steet car stuff these days...

 

According to Strange, they refer to drag racing applications for the aluminum case and state where "gear set life is not an issue". Well as a daily driver gear set life is an issue with me.

They're only referring to hard launching drag cars. The alum. case will distort/deflect more and therefore will be harder on the gear set. It's great for a street car since you don't need as much strength and it's a bunch lighter.

 

You can get working ABS/TCS with a 9". My Moser 9" had both along with 35 spline axles and a locker.

And some of our sponsors are proud of their stuff... I have called alot of them and gotten quotes... the worst so far was 2900.00 before shiping ... and that was supposed to be a sale!

I am tryng to get a full set-up for closer to the 2k mark then the 3k mark!

 

I have talked with 5 sponsors as well.

 

Don't forget a 1350 chrome moly yoke, solid pinion spacer, and 1/2" X 3" screw in studs.

 

Crap! I forgot about the solid pinion spacer . I did spec the 1350 yoke and crossover U-joint and the 1/2" studs .

 

What is a solid pinion spacer and crossover U-Joint?

 

Anyone? "What is a solid pinion spacer and crossover U-Joint?" Sorry guys I am just learning here...

 

solid pinion spacer is a spacer for the pinion gear, just part of the assembly. A crossover u-joint is a conversion u-joint to adapt the upgraded 1350 yoke on the rear end to the stock driveshaft.


If anyone on here is interested and wants to maybe save some money. Stock length housing w/31 spline axles, TCS rings, brake backing plates, bearings (one set pressed on + complete spare set), 1/2x3" studs. Also has LCA relocation brackets and swaybar brackets welded to rear end. Just add a center section setup for 31spline axles and you're on the road. PM me if interested.
