4 lug disc brakes?

SSBC makes a kit for 4-lug front disk brakes (not sure if they make a rear kit as well). National Parts Depot handles the kit, although I'm sure it's available from multiple sources. http://www.ssbrakes.com I installed their HD 5-lug front and rear disks and was pleased with them. Hope that helps.

there was a guy that was working on a four lug disc brake swap for the early bolt pattern cars, but things kept getting in his way. he was working on a four wheel disc system. a few cars that had rotors that fit his wheels, and had the 4x4 1/2" bolt pattern, included the acura gs30(?), a couple of mazda's, and an early nissan or two. you are going to have to fab brackets for the calipers, and at this point you can use most any caliper, but you will need to find hubs that fit what ever spindle you plan on using. the only granada's that had four lugs were the last granada's(81), and they use the fox body 4x4 1/4 bolt pattern, so that wont help, in fact they were fuglyed up fairmonts. best you can do is hit the parts stores and find a counter guy that has some smarts and some time to help you locate hubs and rotors that will fit your application. by the way even marvericks did not have disc brakes on cars with six cylinder engines. my advice would be to stop trying to be cheap about it and either use the aftermarket four lug system, or swap to five lugs on all four corners.

by the way, you can do a 5 lug swap, including wheels, for under $1000. using the granada, or similar spindles, a granada 8" rear, and for wheels that look different and are reasonably priced, use the aluminum wheels from a mid 80's ranger or bronco ll as they fit the early mustang real nice, and the wheels are pretty neat looking.

I'm doing a Granada swap with these wheels.

Got them with tires from one of the V6ers for $300. Only thing is it'll need spacers. But I should still be around $500.

There are also some of the '05 V6 wheels with spinners and new tires going cheap on ebay. I'm thinking those might look good on a classic.

Hi All,

Want to do a disk brake conversion to my '65 - 6 cyl mustang and think budget wise the Granada one would be best. Is there any rotors that would work with this swap so I could keep my 4 lug aftermarket wheels??

I know there are kits out there but budget is important right now. There must be lots of Ford 4 lug rotors out there without using the 5 lug ones??

6 cyl Granada's? Mustang II's?? (I did a search but found nothing except for rear brakes)

Perhaps you would like a response that answers your question? The rotors (but not spindles) used on Pinto or Mustang II will work. They are 4 lug, use the same calipers and bearings as Granada. They can be purchased new for $19 ea + shipping. That said, there is no guarantee that your wheels will fit these rotors. They probably will not, unless they are designed for disc brake application.

mII and pinto use smaller rotors than granada and the 4 lug pattren is diffrent than the early stang pattren as stated before good luck
