With your mods and those tires, you don't *need* a 12-bolt yet. If you ran at the track with slicks, I would say be ready to buy one soon. What do you mean by 'highway monster'? You want to race at high speeds? Good fuel economy? You can leave your gears alone if you're not worried about racing off the line.

If you have the money to blow on a 12-bolt now..you should get one. The stock rearend sucks, and it would be nice to be safe than sorry.

you should be fine if you have an automatic...power doesn't necassarily kill the rear...it is the shock (m6 cars are violent in this area, producing many of the broken 10 bolts) and please don't get 2.73's that is just too low of gear...3.73's are nice for an auto

id prepare for it to break and if it doesnt good.



if you want a highway monster id recommend a cam and gears.

landonew

it is an m6. Yea, what i meant by highway monster is that I race mostly on the highway, from like a 40 or 50 punch. Its just that it s my DD, and i cant afford to have it in the shop for a long time, so if i need am in danger of busting the 10 bolt, then i want to go ahead and order a 12 bolt and install it. If not i would rather get intake manifold, throttle body cam ext.... I guess a 12 bolt is my next mod though. Is a good investment, cause i will eventully need one. Thanks

With what you want I wold say the ten bolt would hold up for now. I think it is the hard lauches mainly from a stand still that breaks it most of the time. I have any A4 with et streets on it. it pulls the wheel up on lauch about 4 inches 60 ft was 1.63. It has made 30 passes at the track no proplems yet but thats not to say the next pass wont break it though. also the 12 bolt may cost you a few horses at the rear wheels. So if you want to try and keep it a ten bolt be prepared because some have better luck than others but with you intenitions I say keep it ten until you get some major mods.

you can always get a girdle and studs to make it a little stronger...as long as you aren't doing hard launches you should be fine

i got about 130 passes on my 100% stock 10 bolt and about 150 street races before it finally died. 4k dumps with nittos. it just depends on your luck. also - change the fluid a lot if you beat it alot.

landonew

yea, ok. Will just try not to launch it for a while. So just curious. Ford 9" vs. 12 bolt ????? I heard the ford was heavy. Whats the pro's/con's of each?

BlueSix

The 9" is heavy, but indestructible. 12 bolt rears break a lot more than people would lead you to think.

2MuchRiceMakesMeSick

My 9" shipped was 199lbs. My freinds 12 bolt shipped was 191lbs. Ive seen 12 bolts break with 450hp. I dont think ive ever seen a 9" with spool and 35 splines break.

Joker

Also with a 9" you can't get a three channel setup just yet from what I understand. That is, if you have antilock brakes and no traction control, you can't hook this up to a 9".

If you have a 4 channel, both traction control and antilock brakes you can hook this up to a 9". If anyone has actually seen a 3 channel setup for a 9", please let me know!

landonew

I dont know if I have traction control. If I dont want it but have it, can i just not connect it. is the 9" any more xpensive?

Actually, the Fabbed 9" from Jaybillsingey(sponsor----->) is abpout 30lbs lighter than the 12 bolt. From what i've seen here, the 12 bolt is a "fad" if you will.....but doesn't seem to be reliable enough to stand up to the $2000 price tag it cost to get in the door with one.


Me...I'll be spending the extra 1K on a Fabbed 9" from Jay when the time comes. Why? Cause I know if i spend the little extra the first time....it'll also be the LAST time i have to mess with the rear end!

A good 9" averages about 2500 from what I've seen, a nice twelve bolt from strange is about 2200. These prices are average dependent upon axles, posi units, detroit lockers etc...Be prepared to spend between 2000 to 2500 for either unit. The 9" is stronger than a 12 bolt all day long, but most weigh more than a 12 unless you get a fabbed one, and the power loss is greater in using a 9" than a 12, but to know you won't break it as easy is worth the money to me.

I don't know about disconnecting traction control myself. If you had it you would most assuredly know I think.

BlueSix

The nine inch for my GTO is $3600, but it is an IRS 9".

KrazyDan

But with the extra traction you "use" from a rear end, are you gonna be slower(with 4.10's).

Bluehawk27

um the billingsley 9" street ready package is a fully assembled unit for 2300. Right in line with all the other units and stronger. This is the one i'm lookin at. Now that i have a cam/headers.

Edit: I must be drunk. Disregard, i just re-read the web site.

2MuchRiceMakesMeSick

Yes you can still have ABS and ASR/TCS with a 9". It only works on 4 channel cars but if you have ASR/TCS then you have a 4 channel setup.

People start rumors that you cant have a 9" with a 3 channel setup and its silly because if you have a 3 channel you didnt have TCS to begin with.
