Anyone know of a good rear brembo setup that balances well with the front Cobra R setup?
One thing to remember about adding a fixed caliper to the rear of your car......If your car is street legal, and needs to pass a yearly inspection, then you need to retain some form of parking brake. A lot of these kits do not come with a them, because unregistered uninsured track/race cars have no need for it.
I came across this on the Wilwood brake site for the Ford 8.8 rear (4 piston) that supports a parking brake - might be worth checking in to. Scroll down to the Ford applications.
The SVO has larger REAR brakes than front brakes....I'm just saying
Those brakes are CLEARY too much brake for the rear. I know two people that have this exact rear brake set up. One of them ended up going through turn one at Road America backwards and the other one took it off of his car because it was too much rear brake.
Friend #1 ended up having to put a brake bias adjuster on the car to crank the rear brakes on the car way back and the other friend has not put the rear brakes back on a car yet and when he does, he will also need a brake bias adjuster as well.
My 'performance' take on it would be why would you want to INCREASE rotating mass and unsprung weight with those big heavy four piston calipers and thick heavy rotors??? That means you're going to accelerate slower and handle worse. How is that an increase in performance?
FWIW

I'm running Wilwood SL6 (front) and SL4R (rear) on my '09 GT (S197) and have NO performance problems on the road courses. You can also control brake bias with different types of pads (less aggressive), e.g., running Hawk DTC 70 (front) and DTC 60 (rear). A 4 piston rear caliper is not too much for these cars - perhaps for the older generation (pre-2005 Mustangs) where they carry more weight on the nose vs. the rear.

Nope, I'm still nose heavy (front - 56.6 rear - 43.4). From what I've read the larger rear disc were to help in nose dive, but as you can see I don't think it helped much (Yes I'm whoring a pic...)That could be on purpose, your car has a higher percentage of the overal weight on the rear than V8 Mustangs... even IRS ones, if I remember correctly...:shrug:
Hmm an IRS equipped, SVO with 14" front brakes, and a 2.5 Ranger bottom end.:dw::bash::-D That could wreck someones track budget.:-D
I have run 14", 4 piston, kit on the front of my '03 Cobra, and left the stockers in the rear. The car braked great with no bias adjuster and no funny handling characteristics.
I would probably consider increasing the rotor diamater, but leaving the stock caliper before going to a 4 piston rear kit.
The Panoz racing cars had 13.1 fronts and 13.0 rear Brembs and the front and rear Brembo set up on this mach 1 is based off of the Panoz set up shown here:Panoz GTRA Chassis although this Mach has 14" front rotors. Panoz did make a Brembo set up for the Cobra IRS, but it may no longer be avalable. All of the Brembo rear brake parts such as the parking brake, caliper and rotor are avalble new, but they are not cheap and You will have to fab up your own caliper mounting brackets.

Maximum Motorsports has a Willwood brake kit for the Cobra IRS designed to work with the Cobra R front calipers:
