    16" rims and 12-12.5 discs??

    I realize 16" rims aren't used that much, maybe no data available. However I have a set of 05 GT calipers that are available for use. I want 12" rotors, at least. SSBC site shows 12.5 rotors for 16" mustang wheels, which would be fine.
    Question is; Does anyone have any real world info on 12"+ rotors with 16" rims??
    MS told me a way to check them out, butt I'd hav'ta pony up a few bucks. I'd rather not have to re-invent the wheel.

    I have 16 inch rims on my 95 Mustang that I race and 12.25 inch rotors. The calipers and rotors are Wilwood. I have about 3/16 inch clearence on the ID of the rim. The stock 16 inch rims do fit with a .25 shim. I run my rain tires on those. My aftermarket race wheels fit with no problem. They are a copy of the Cobra wheels.

    I have the Wilwood 12.19" rotors on my 16x7" wheels.  4.25bs.  (1966)  I have about 1/16" clearence with the thin shim that comes with the kit.  I do not think I could fit 12.25's in there.  But the biggest issue is the width of the cliper as the outside corner edge is what rubs, not the top.  Maybe your calipers or wheels are different than mine around the mounting surface.

    I suggest you mount one side and test the wheel fit before you blast away with it.  Particularly since you have to wire the rotor mounting bolts.

    It should work but the offset might give your problems. You could use those calipers and 70? lincoln rotors make a bracket and you'd have a perfect set up those rotors have same nom thick as the gt mustang. Doing so would probably even fit 15" rims

    12" 1970 Linc Mk III rotors?? I thought they were the same 11" diameter as the Granada rotors I already have.
    This Ford Muscle article: http://www.fordmuscle.com/archives/2004/07/12inchBrakeConversion/  talks about 77 Continental & 72 T-Bird 12" rotors, though the Linc bolt pattern doesnt fit nor do the 72 T-Bird bearing size fit.
    What am I missisng??

    The 1970 rotors are 11.72 a little bigger than the granada rotors. Plus they have the same nom thick as the newer gts and are close to the same outer diameter so the caliper should fit well. Or you can go a little older lincoln or t bird and run 12" rotors and calipers. Like what they did on mustangs on the track know as trans am brakes they were they biggest rotor and caliper then that they could fit in a 15" rim

    You could use the ultra stang rear disc set up not quite as big as you wanted. And then over on west side mustangs there's a guy who sales a set up using 99-04 gt calipers and maurader rotors which fits 16" rims. He doesn't list them I dunno why.  but neighbors is the one who sales them.  Just an idea. http://www.westsidemustangs.com/showthread.php/82353-Disc-brake-conversion-brackets?highlight=Cobra+brakes

    Found it. http://www.westsidemustangs.com/showthread.php/74926-Attention-Curtis-and-Chris-Cobra-front-brakes
