Look at the parts list on the 5 lug page. Then start buying.

ok.. well what is your current rear brake setup?

if you have SN95 GT/V6 rear brakes.. then you need Cobra caliper brackets, cobra pads and cobra anti moan brackets.

You cannot use the front rotors on the rear if that is what you are asking.

You need to buy the caliper brackets from North Cobras.

The parts list can be confusing. You will need cobra Rear Caliper Mounting Flanges (these are the metal plates that bolt to your axle and have two holes to mount the rear calipers to). You need these because the cobra rotors are taller and these will give you the clearance you need as opposed to GT flanges. You will also need cobra caliper brackets (these are part of the rear caliper and slide over the rear rotor and hold the brake pads.) you need a cobra unit because the cobra rotor is thicker than a GT rotor. You can modify GT caliper brackets by grinding them to open them up a little. Thats what I did and it worked well and costs much less.
You will need to modify your existing porportioning valve and install an adjustable valve as per the website already mentioned.
You will also need a new master cylinder from a 94-95 V6, GT or cobra -also mentioned in the website.

I took my time and did mine, it wasnt too complex but it was alot of labor.
In hindsight, I would probably have just went with GT rear discs. The cobra units are only slightly bigger but they will cost alot more to install (specific rotors, mounting flange, pads and caliper bracket).
Good luck

The Cobra rear discs are very easy to do. Just grind the caliper bracket that fits over the disc with a dremel or die grinder. That will save you about $90, ($45 per side). The caliper to axle bracket will cost you though. First you need to decide what length axle you are going to go with, stock Ranger length or SN95. Then you can buy the correct brackets. If you want Ranger/stock axles, look at North Cobra. Great quality steuff. If you have SN95 stlye, look at Disc brakes are us. They can fix you up with the right set up.

If he can weld or has access to a metal brake, you could easliy make your own brackets. I have been thinking about doing this myself, because I want to use a custom length axle. Look at NorthCobra.com and they have pics of the brackets on there. Just do a little measuring and you will get it done. The ones that northcobra sells are just heavy sheet metal that has been bent and drilled for the dust shields. It is totally possible to make your own.
