I Want to go for a huge upgrade but Im not sure what to do first, should I buy the heads & cam first or the rear end.Its the M6 (6speed). I have heard stories about the rears going out fast. I recently put BF G-force Drags on it and the diff is huge in launch, But will the Rear end hold up? Im so new at this stuff, its my first F-body.

Thanks for the advice--

If your an A4, then ur alright for now, but if your M6 (6speed) then you'll need an upgrade sooner or later.

But if it was me, i'd go heads and cam with a set of lower control arms. Thats me though

if it's an automatic go for a stall, then H/C.

If you're a manual do for a rear end with at least 3.73s, maybe even 4.10s if you don't drive highway much

Go for the rear, the 10 bolt (on average) won't survive long with sticky tires and hard launches (especially on an M6).
Look at it this way, you get the rear, you won't be limited by it when you build your engine, and if you do the engine first, and you do break the 10 bolt, then you'll only have the cash for another 10 bolt (or have a broke car, and nothing fun to drive/race)

No, think of it this way, u wont always have 3k lying around for a hc swap, but you will usually have 300$ for a new 10bolt! or just dont go from a stop do all ur races from a roll until u get a good rearend, trust go for the power first.

IF its not your only set of wheels..I would go H/C ...otherwise I would go from the ground - up.....don't wanna be stranded.

I belive Im going to go with the rear-end. Does anyone have any suggestions with what type I should go with. And I would like to thank everyone for the advice^^

It depends on what you want to do with the car. If your plan is 6K side steps off the clutch then you better go for an upgraded rear end 1st. If your building a highway warrior that will not see the 1320 then by all means go for the H/C upgrade.

Take my car for example power for high to mid 11's and i'm stuck in the 12's as I cannot run sticky tires for fear of breaking the 10 bolt.

I want to beable to pull the tires off the ground on the launch at the traffic light cause the nearist track is about 300 miles away.

that aint gonna happen unless you got stickies. i would go with a 12 bolt. simply because a 12 bolt can be built to hold 1k hp and it takes less power to turn than a 9 inch. and who wants that F*** **** under our GM cars.

Ford 9" with 4.10 gears. It might be a little noisy, but it will be bullet proof.

unless your shooting for 1000 hp there is no need for a 9 inch. besieds a 9 inch takes more power to turn. so 450hp to the wheels on a 12 bolt is like 442 in the 9 inch.

Will the standard Moser or Strange 12 bolt hold that much? If not what do you have to upgrade? I am really interested because I am in the same situation.

the moser with 33 spline axles and an eton posi will hold up to i think around 700-800 maby. your best bet would be to call moser and tell them your power potential and future and they will tell you what is best for you. most people on here run 12 bolts, they seem to be the best bang for the buck

BlueSix

I'm more of a do it once and do it right kind of person. So even if the 9" does take a little more power to turn, in my eyes it's worth it. People have broken 12 bolt's with far less than 1K hp. IMO for a 6 speed car there is no other choice than the 9".

BlueSix

And i really don't see a posi holding 800 hp.

bww3588

iTrader: (49)

well if your goin for 800 hp you need a full spool but if your only trying to hold 500-600 hp then a 12 bolt with a posi is fine. IMO

for me im buildin a street/strip car with about 500 at the crank with a six speed. so a 12 bolt is what im goin with

a friend of mine had a high 10 sec. street / strip car on a stock 10 bolt, and he used stickies at the track. ( not FULL stickies, they had the groove in the center ) yes it was a M6 also. it's just my opinion and others will disagree, but build your car up and dont worry about the rear end, when it breaks, then you replace it. that's my plans, no need to fix something that ain't broken! ( yet )
