How to remove the abs stuff from my gt?

How should I go about doing this? Do I need to run all new lines? Thanks.

I dunno, but if it's still functioning, I'll take all the wiring harnesses off your hands.

I'm gonna go ahead and throw a flag on this one . CMC might not allow ABS but 1/2 the field in AI is running it. http://www.nasaforums.com/viewtopic....ht=abs+removal
I went back through my rule book and don't see anything banning its use.
What is the weight of the pump? It'd have to take 10 or 15lbs off the left front before I'd even consider it.

7.8.3 Anti-lock brake systems are prohibited except for an unmodified OEM system, which includes ABS valve body and electronics as delivered from the factory. Updating and backdating of factory ABS systems into newer and older cars is allowed. Calipers are unrestricted.

Edit: This is for AI.

b. Ford vehicles: 12” diameter and 1.125 thickness
4. Front calipers may be updated/backdated from any car of the same manufacturer listed in Section 4. Eligible Manufacturers/Models, and shall utilize either 2 non opposed pistons no larger than 38mm in diameter or a single piston no larger than 76mm in diameter with the following exceptions listed below:

Now that that's cleared up, way the hell does it matter why I wanna take it out?TennGT Even if it was legal in CMC I would still take it out because I have more trust in my right foot than the stock stuff that kick's in at all the wrong times on R compounds. So take that bs flag and sit on it.

Slow down, the B.S flag stands, you stated that ABS was illegal in AI, if the rules for CMC require you loose it OK. What I was trying to get at was why take it out if the rules allow it, seems like there would be some benifit gained and there might be other areas to loose a few lbs.

I was under the impression that a lot of the rules where carried over into AI. Has I dont plan on runing in Ai I have focused on the cmc rules. Now does anyone know the proper way to remove it?

I found this thread on the CMC forums.
http://www.camaromustangchallenge.co...ht=abs+removal

Also, there is a guy on Corner Carvers that runs a 99+ Mustang in CMC. You may want to contact him and see what he did. His screen name is GT4Point6.

Looks pretty lame. You can't run cobra brakes, so that just excludes all cobras? Nice advantage to the 'maro's for power output then assuming the other rules are as strict.

The module is heavy. I didn't weigh it, but I'm guessing between 12 and 15 lb's. Plus, that weight is in the nose. It is pretty simple. The best solution is new lines, and install a manual brake bias. However, the quick and inexpensive way is to remove the module. Install a "T" onto the front line that comes from the OEM brake bias (It is clearly marked on the ABS module). Contect each side of the "t" to the left and right front caliper lines. Install a coupling for the rear brake line. It will require several fittings and maybe more than one trip to Auto parts store, but it's just a matter of making the correct connections. Again, the lines are marked on the ABS module. Before you break them loose from the module mark each line with masking tape and a marker. It looks a little crazy when your all done, but it will work fine. I race in AI and a manual brake bias is the way to go. But, if your running CMC ABS is illegal. I personally do not like OEM ABS on the track. Atleast not the system in a 95 Mustang. You loose too much pedal feel and control. Plus you get lazy and just mash the brake pedal to the floor. Not a real good way to learn braking finesse.

abs is not legal in cmc.

You can run the cobra PBR calipers but you have to modify the brackett and mill down the rotor to 12".

All Cobras are excluded. However, you can run Cobra brakes, but you have to have the rotors cut down to 12" to be legal. The F-bodies have a higher minumum weight. The Mustangs are winning more races across the country.

Removing the ABS sounds like a PITA. Disabling it is easy, just remove one of the wheel speed sensors and the system shuts down.

I do autocross, open track and solo trials and I love my ABS. No tire flat spotting with it and since I seldom need to threshold brake anyway it isn't an issue. Seems to me that rules that disallow it are are frakking stupid. It's standard equipment on every V8 F-body and Mustang for about the last 10 years and it does help prevent loss of control.

all in the name of cost containment. A lot of the mustang's and camaro's are earley 90's late 80's. \Where abs wasnt avaliable. Its a real Cheap class to start racing in so Iam goin to stay with it. I'm still not a fan of abs.Just dont like the feeling of it.
