I am currently working on an overview on the parts necessary and the options and choices you will have doing your brake upgrade. I will list some of the specific combinations and parts needed to successfully upgrade your 1979-1993 Fox body Mustang to the more capable SN95 - 1994 and newer Mustang brake components. This will include swapping to 5 lug axles, use of the front & rear SN95 brake components, either GT V6 parts or the larger Cobra brake components. There are other ways of doing a bigger brake upgrade including the use of aftermarket kits from companies such as Baer, SS brakes and others but we will focus on using readily available (cheaper) parts! If there is something you would like added to this or if a necessary correction is needed, just send me an email with your comments. Take a look at my Avatar on the right. This is a picture of what Cobra front brakes and a coil over suspension looks like on a fox body Mustang.

Rear brakes components and axle choices:

Rear axles - either SN95 axles from a 1994-1998 Mustang V6, V8 GT or Cobra. These axles ar .75 inches longer per side. If you use these axles then you may be limited to only 8.00 inch wide rear rims unless you want to modify your rear fenders for clearance.

If you want a wide rim and tire combination on the rear of your car then the use of the stock length axles would be preferred. These can be obtained new from manufacturers such as Superior, Moser and others. This is a wise choice if you are also planning on building a high horsepower setup as you will want stronger axles anyway. You can also choose to find Ford Ranger axles from the junk yard. No matter what stock length type axle you choose you will need to obtain a set of offset rear caliper axle mounting brackets to allow the proper positioning of the rear calipers. These are available from a variety of sources. We also have carried these at various times. Next consideration is whether you want standard Mustang V6/GT brakes with their 10 inch rear rotor size or if you want larger 11.65 inch Cobra rear rotors. This decision will determine what caliper to axle mounting bracket you will need. The Cobra brakes use a taller bracket to allow for the taller rotor. The bracket places the caliper up higher to provide proper positioning. Offset brackets are available for both GT and Cobra brakes. I normally recommend going to Cobra brakes unless on a budget as the GT/V6 parts are cheaper and more readily availible. Now on to the calipers. If you are doing GT/V6 brakes either the GT/V6 will work. They are identical. If you are doing a Cobra rear brake setup either the Cobra calipers or the GT/V6 will work for you also! You may have to provide just a small amount of clearance for the slightly wider Cobra rotor as the larger Cobra rotor is also a vented rotor. This also provided addtional cooling for the Cobra brakes which of course is better. Normally only a small amount of clearancing needs to be done. A small grinding stone, dremel tool, etc. will work out just fine. If it is too close the edge of the rotor will drag. This will be apparent just by turning the rear wheels when you start to assemble the brakes. Last thing to consider also is to properly space the rear caliper so that it is centered over the rotor when bolted down. The use of a thin washer as a shim between the caliper mounting bracket and the axle mounting bracket is common, quick and easy.

More to come.........

For now please look in my Ebay store if you are in need of specific components such as front and rear emergency brake cables, front and rear brake hoses, brake line adapters, adjustable proportioning valves, proportioning valve plug kit, master cylinder kits including the 1993 Cobra MC, other year replacement e-brake cables, many Ford Racing parts and accessories and much more!

Thanks for looking.
