Rear brake upgrades?

My personal combo is Focus RS calipers (same as 00 Cobra R) in front and relocated stock calipers w/Cobra rotors in back.
Any front brake upgrade for an SN95 will fit a 92-up MN12 if you're willing to do the hub swap or redrill rotors.
And since there are adapter brackets to fit S197 brakes on an SN95, any S197 front upgrade should work, too.

Can you post a picture of the rear cobra brakes?

So you had already decided what direction you were going & placed orders for the nessasary parts prior to your post on Friday?

There are no Brembo calipers that just "fit" these cars. I used ats calipers that had to be modified by machining them. With a 14" rotor the probably wont clear fwiw. I just put cobra rear rotors on mine with a relocation kit sold by David Dalke at super coupes unlimited. I had to use a wheel spacer with my wheels to get the calipers to even clear the face of the wheel. If you look at mine there's only maybe 1.5" of clearance at the rotor and even less from the caliper to the inner barrell of the wheel.

I mean they are just cobra rotors with stick calipers. What are you going to be doing that would require Road race type brakes?
I am trying to get the brake bias closer to stock. Going from single piston front to two piston front moves the bias forward. Going four piston moves it more forward. I do some autocross and brake bias is important you lose or gain stability with the wrong brake bias. I am trying to find an option for the rear brakes to add more rear bias. This would be a bigger piston single piston or even better an increase in piston count for the rear. I ordered the rear bracket in the hopes I can make it work. It is for a mustang, not a thunderbird. I am not sure it will work and ordered it in the hopes that it will or at least I may be able to modify it to get it to work. This is the point of my request. In fact I am not sure the front will be able to work so I ordered some used calipers in case it doesn't. My question is to see if there are any other options that people know of. I have searched and this is my hope to be able to get what I ordered to work.
I have those already and it is a bit too forward in brake bias. I am also rebuilding the engine to make more power so I would like better brakes to go along with the increased power. As mentioned below I do some auto crossing and with the additional power I will be making I am hoping to increase the braking as well.
I will be using Xts front calipers and and S and S engineering kit to allow them to mate to the mustang spindles. I upgraded my spindles to 93 and newer spindles to get the cobra caliper to fit so the kit and the Xts calipers should fit the tbird. The S and S engineering kit allows you to knock out the plugs on the XTS calipers and press in their kit to match up to the mustang spindles.
Here is the link for the kit:

your not doing auto cross with 20" wheels and tires. If it won't fit it just won't your not going to will it to work because of an idea in your mind. in the picture you posted you have 17x8 cobra rs on your car. My car is probably the most modified supercoupe in the country and I am just trying to help you save time and money not to mention frustration. You say you've ordered brembo brakes but no one makes brembo brakes for our application. A common modification for our cars and 99 04 mustang cobras is adding Cadillac ats brembo calipers but they have to be machined. I was going to try a 14 " rotor and it just wouldn't fit. When I tell you the brakes on my car will absolutely put you through the windshield I mean it. I have looked extensively into upgrading the rear brakes even further but I havnt found anything that would work and still give me an e brake. You can do what you want i was just trying to save you the trouble.

That kit is for a mustang. The issue you may run into with that is #1 the suspension on a tbird and mustang are different. Tbird suspension loads the front shock straight up and down and some wheel offsets that mustangs run won't fit our cars for that reason. i told you I had an issue with clearance on the ats calipers as it was the xts calipers are 1/3 bigger. The mustang suspension has a McPherson strut that allows different wheel offsets. I hope it works for you but like I said before I hadn't found anything much better for the rear that was worth messing with.

if you notice that guy had wide body fender flairs and had probably cut his stock wheel openings. with a 20x10 rear I have to run a 235 30 20 to clear with the fenders rolled and they still rub at times. I also have qa1 coilover suspension all the way around, Aje front subframe, custom tubular upper rear ctrl arms and mark 8 lower ctrl arms.
Did you watch the video? The S and S kit changes the mounting points for the calipers, no machining required. I had 17x9 wheels but as I stated I now have 20" wheels. Why won't the 14" fit?
What offset are the wheels you are using?
