73mm Brake Caliper Help

my 82 Capri with 88 spindles along with 73mm calipers and turbo t-bird rear disks and svo mc work great over the stock crap and with 375 hps it makes me feel better to know i can whoa this beast!

For you guys that actually think using these calipers works, take this into consideration.
The stock calipers are 60mm, you are adding 13mm worth of piston, and if i'm not mistaken the pads are extremely close to the stock pads except they clamp into 73mm pistons.
So what did you really change? You get a meisly half an inch more of piston, pressing on the same exact spot on almost the same pad.

For brakes to work better, you need more rotor surface to do away with heat, more pad surface to grip better, and pistons to press down on the added pad surface. Without all three, you might as well have none.
Take note of cobra PBR calipers, 2 pistons spread out, to press on the entire pad evenly and has a much wider pressure patch, thus all of the above happens.

Now consider your extra 13mm of pressure from what is a very similar caliper to stock. What does it do? About the only thing i can figure out that it does is confuse the parts guy at pepboys as to why you are putting lincoln brake pads on your mustang.

I agree x3, but what I would like to know is the difference between the Mustang and Lincoln rotors. If there were no functional benefit to engineering, producing and supporting a 73mm caliper there would not be a 73mm caliper. If the 60mm was functionally similar to the 73mm why would Ford produce a 73mm unit?
