Hi.
I finally got my Mustang and it's a '75 fastback.
In the months to come I intend to do a complete rebuild of the rear end. We're talking 9" axle, 4-link (possibly with a watt's link) and coilover shocks.

What brakes should I use?
I have looked at Wilwood and they have some very similar brake kits.

They have some kits that are very similar and I really don't know the strengths and weaknesses and I was hoping you guys could shed some light on it.

Kits:
140-2113 Small bearing ford
140-2115 Big Bearing Ford 2.36" offset
140-2114 Big Bearing Ford 2.54" offset
140-2118 Big Bearing Ford (New Style)

Is there any one of these that's better than the other?
Will the 12.19" Rotors fit inside 15" rims?

The bigger the bearings you can get, the more stable they would be but for dragging, you could go with what Wilwood recommends. Those brakes are probably what you need, but forget 15's. Those rotors probably would require 17's to clear the caliper properly. Even with 16's you'd have to modify the caliper to clear so find out what wheel manufacturer makes the size and style you like before you buy anything.

Bummer

Back to the drawing board. How large rotors can I squeeze in with 15" rims?

You might be able to get 11's but the clearance issue is with the caliper. Maybe Wilwood can help on that matter, I wonder? I know they have different caliper options too so maybe something can be done.

I just got a reply from summit and apparently the WIL-140-2118-DR brake kit is designed for most 15" wheels?
It requires an inside diameter of 14.06".
