Yeah I've heard that the turbo coupe 8.8 will work also. I think you can go newer than 95 Mustangs also, but I'm not positive

Mark VII fronts should do the job for you. Not sure about the rear, eventhough it's got the same 8.8 as the Stang...

If you want 5-lug fronts just get the mark VII rotors and calipers. The spindles are the same. All you really need to do if you want 5 lug is just buy 5 lug lincoln rotors at a parts store or get them from TMD for $70 for the pair and they are slotted. If you dont mind having drums then just get 2 axles from the left(drivers) side of any 83-92 non 4.0L Ranger or Bronco. Or the right side from an Aerostar.

Turbo coupes are 4 lug, so you'll still need to swap axles and rotors on that rear to.

For 500 bucks that's not too bad for getting 5-lug and improved handling...

Been there and done that! With success!

It takes 2 guys the first day to get the old rear end out and the new one bolted in place. It takes 1 guy another whole day to do the brakes.

Auto trans Turbo Coupes come with 3.73 gears and manual Turbo Coupes come with 3.55 gears. I choose 3.55 since I do more highway driving.

You will need a several sets of fittings, I recommend that you get them from Matt90GT's website, http://www.svo73mm.cjb.net/. Read Matt's instructions thoroughly, everything you need to know about the brakes is all there. You need to be patient and follow all the internal links, and there are many of them. You will need 2 fittings in the rear to adapt your old brake tubing to the TC disk brakes. The fittings go between the steel tube and the caliper brake hose. You will need another set of fittings to make a 2 port to 3 port adapter. To make life simpler, just buy the kits from Matt. You could piece them together, but it's not worth the time unless you work at an auto parts store with all the fittings ever made. You will need to drill the quad shock mounting holes 2” below the holes drilled for the Turbo Coupe mounting points. The bolts are metric, so don’t loose them or the nuts. A 15/32” drill should be about the right size unless you have access to metric sized drill bits. Going without quad shocks is not an option unless you have aftermarket parts to soak up the wheel hop.

You will need a proportioning valve, Summit has one for $40 + shipping.
You will need a kit (FMS makes the part) to gut the stock proportioning valve, Summit also has that, about $10.

You will need a new master cylinder, see Matt's site and make you choice. I used a 94-95 Mustang master cylinder. Note that rebuilt 94-95 Mustang master cylinders do not come with a reservoir. That means a trip to the junkyard and some more money spent.
Your brake pedal may be very hard and almost impossible to lock up the brakes. I had to replace the front calipers with 73 mm calipers from a 91 Lincoln Mark 8 to get the braking performance up to par.

Bleeding the brakes will require 2 people and some coordinated effort. I don’t recommend using you wife or girlfriend to pump the pedal – they get offended when you yell at them. I used a homemade power brake bleeder constructed from a garden sprayer and some fittings from Home Depot. It cost about $25 and was worth every penny.
See http://www.mustangcentral.net/tech/brake.html for help with the emergency brake - the stock setup tends to lock up and not release properly.

All in all I have been very pleased with the results.

You will need Sn95 parts for the front setup.

Mark 7 rotors won't work with those wheels...you'll never get the center caps on

So, to summarize: To convert from four-lug to five-lug on '87-'93 Mustangs, get two driver-side axles and two five-lug drums from the rear of a Ranger pickup (this is the same as the Motorsport kit M-1126A, but the price I paid is nowhere near the kit's $227 list). For the front, use the 11-inch rotors from a '91-or-older Mark VII. All of the original parts will work, including the bearings.

Dont use the explorer stuff. And the mark vii's can be used if you use spacers. My car has them and it fits just fine, and works great.

And '98 Cobra rims too...

You need SN95 Spindles use '94-'95 for the stock track width.
In the back you can use 2 Ranger drivers side axles, or 2 Aerostar Passenger axles, OR 1 Ranger Drivers side axle, and 1 Aerostar passenger side axle. You can use the drum brakes off the Ranger.

OR you can use Lincoln rear brakes, but this way is more complicated. They are discs.

You HAVE to read up on this site, we can't stress that enough.....it has everything you need.....everything..
http://svo73mm.cjb.net/

oh yeah, Explorers use 31 spline axles, and I think are longer, won't work.
