Rear disk, still 4 lug...

SuperDucky9 · Jun 11, 2010

Alright, so this would be my first post. I recently got my 89 GT off my brothers shop, and they were redoing it. The guy they got it from bought it brand new in 89, rolled it in 92, and it sat in his barn until we got it in January.
The guy converted the rear to disk, and its also an open-diff now too. Still an 8.8, still 4 lug..

Any idea what rear end he put in it?? I bought pads for a 87-88 turbocoupe, and they didnt work.. The modification was done sometime before 92..

Pictures? Are the rotors vented? Rotor diameter?

I bought a used 4 lug rear disk settup for my '88 vert a couple years ago.

It came off of an '87 McClaren Mustang. I haven't had to buy pads yet but I was told they are the same as the '93 Cobras.

Good Luck,
hope this helps

93 cobra rear disks same as 87/88 t bird turbo coupe, which he tried.

That rear was not original to an 87 mclaren as they came with standard fox drum brakes.

Onefine88 · Jun 12, 2010

HMMM,
I watched them being removed from the McClaren at a friends Speed Shop. I thought it was an '87 but I can be wrong. I don't know much about the McClarens. I wonder now what year that car was.

The guy did tell me to use '93 Cobra pads. I guess I'll find out soon enough when that time comes.

Hopefully not the hard way.LOL

Hey, it stops good though

Could be the old cadillac conversion setup for the rear.

Take the part numbers off the calipers.

SuperDucky9 · Jun 12, 2010

Pulled the wheel off and took some pictures. Ill be getting those up in a bit. Couldnt find any numbers on the calipers, but it did say VARGA on it. Is that the manufacturing company, or something significant?

Mustang5L5 · Jun 12, 2010

Yes. They make the calipers for the sn95 and the turbo coupe,

You sure the Turbo coupe pads didn't fit? I am not aware of any other 4 lug setup using varga calipers unless it's a modified sn95 setup for 4 lug

SuperDucky9 · Jun 12, 2010

Pretty sure. Dont know how to word this, but the pads we pulled off the calipers were equal length to each other. The pads to be put on were larger and one was about an inch smaller than the other...
And yeah, the set i bought was for the rear disks of a 87 turbocoupe.

SuperDucky9 · Jun 12, 2010

Alright, i know some forums want pictures different ways, but im going to just throw up a direct link to them on Photobucket.

mark7 axle, with turbocoupe rotors and axles....

SuperDucky9 · Jun 12, 2010

Any idea why the turbocoupe pads didnt fit? Is there another possible year i should order and try?

Mustang5L5 · Jun 12, 2010

I agree. Those are turbo coupe brakes.

Maybe they senT the wrong pads?

SuperDucky9 · Jun 12, 2010

Im going to have to assume that they did...
Err, ill take them back and get a new set.

Mustang5L5 · Jun 12, 2010

Pads should look like this

SuperDucky9 · Jun 12, 2010

Yep, definitely didnt look like those. haha. Well, ill take mine back, and hit up MM. I like dealing with them, although their shipping time seems to be a bit long. Of the 2 or 3 orders ive placed with them, it took 2 days to just process the order, then almost 4 days of shipping.. not counting the weekend.

SuperDucky9 · Jun 12, 2010

So it has the same pads as a 93 cobra rear?

Mustang5L5 · Jun 12, 2010

SuperDucky9 · Jun 12, 2010

Rotors and calipers the same too?

Onefine88 · Jun 13, 2010

After looking at Superduckys pics I removed a rear wheel and looked at mine.

(Same brakes). Thanks guys you confirmed what I was told when I bought the brakes. '93 Cobra/'87 Turbo coupe it is.

Superducky, You will enjoy the extra stopping power of these brakes over drums. "I have"

Couple extra things we did on my car to get the most out of them was: I bought an SVO master cylinder and gutted the GT stock proportioning valve. Then I bought a FRPP adjustable proportioning valve and mounted it on the firewall brakelines.
On the front you can upgrade your calipers real cheap by using SVO/Crown Vic 73mm piston calipers. These are less than $50 each at Autozone and use the same pads and rotors as your stock parts.

I did all this to my '88 and really was a great brake upgrade for very little money.

Mine stops as good as my stock SSC brakes.

Good Luck

Rear disk, still 4 lug...
