The good thing about adding the OEM adapters is you can paint them and the parts of the axle. I painted the adapters (they came bare) and got rid of all the rust back there

I like the bracket idea because of the simplicity of the brake upgrade. If the brackets prove to be durable, I may go that route as my next mod (following going to the dark side).

Thanks, everyone. I hope this thread helps others with the same issue. A nice, reasonably priced option, and only a few parts need to be purchased, while using existing stuff - I like saving $$. The 2" larger rotors do a good job dissipating the heat, so I think I have this problem solved for track days! Post up your opinions, ideas, results!

LEXiiON

I don't track, but over the last 2+ years i had this installed, i found no problems at all. It looks sooooo much better, especially with larger rims in the rear. Those cars should have come stock with those brakes IMHO.

Agreed, the rear brake set-up stock is pretty weak. Can you believe the Boss and Boss LS came with this 11.8" rear rotor and single-piston sliding caliper set-up? Same as GT, with only stronger lines. Not enough, IMO. Every new Camaro SS came with 14" rotors and 4-pot fixed Brembos, front AND rear. C'mon Ford!

^^ 100% Agree

I think it is weird that the rear axles need to come out just to do a rear rotor swap...

SpectreH

It's not the rotor swap, it's the backing plates.

Hey so I thought I read in another thread that the drawback to upgrading to Brembos in the rear was having to R&R the rear axles. So could you theoretically accomplish something similar by swapping one's front Brembos to the rear and putting the GT500 Brembos in the front? That sounds like some massive stopping power and would look sweet.

Hang on for a moment. My upgrade is NOT Brembos in the rear. In order to have a fixed caliper (Brembo, or other brand) in the rear requires a different set-up entirely. My upgrade is swapping a larger 13.8" rotor from a 2013-2014 GT500 to replace the stock GT/Boss 11.8" rotor. It needs new relocation brackets, and if you use the GT500 brackets (as I did), you must remove the rear axles on both sides to accomplish this. Adding 14" or 15" Brembos with fixed calipers to the rear is a much bigger (and more $$ expensive job). Certainly 6-pots in front, and 4-pots in rear is the ideal set-up, but very expensive. For mild track duty, and easy-on-the-wallet expense, plus re-using existing components to save money...my way is pretty good, IMO.

Sorry. I did a bad job with that post. For one, I've had rear Brembos on the brain for a while now and re-reading my post I realize others could misunderstand your original post. For two, I thought it was more on topic than it probably ended up being. For three, it failed to properly acknowledge how cost effective your solution is for the most significant problem with the rear brakes, which is not cosmetics, it's adequate stopping power at the track. Not overengineered, expensive "ultimate" stopping power, but stopping power that works and solves a common problem at a reasonable cost.

To my defense, I know lots of people are interested in rear Brembos as well (perhaps more money than brains, perhaps it's a cosmetic thing) and I thought the primary discouraging factor was the removal of the axles. I didn't even think about the difference in cost, only that you made the axle removal sound pretty routine and I got a little too enthusiastic.

LEXiiON

The axle removal isn't really difficult nor hard to do. The only thing that makes it horrible, is the smell of the diff fluid. Man that stuff stinks!
I took the opportunity to swap out the rear diff cover for the finned aluminum one, once I was at it.
As i said, axle removal is simple, as outlined in my install guide.

No worries, berserk. I get it. Shelby American offers a 4-pot fixed rear set-up. And it is very expensive. Apparently it's tougher to install then my solution, because the solid rear axle was not intended to have large rear rotors with fixed calipers. I did wonder if the GT/Boss/Brembo front 14s with 4-pots would ever transfer to the rear, but I don't think they are engineered that way. Too bad Ford did not get the brakes right from the start. You put 400+ horsepower in a sporty two-door coupe, you would think you'd get a robust braking system. It's like the rears are an after-thought. Too bad. It means drivers like us have to come up with something to fix it. I'm a cheap bastard, so I think I found the least expensive way. Who knows, maybe someone else has done it better/cheaper. If they have, I hope they will share their story with all of us.

Mr. V

Do you have the parts numbers for the bolts?

LEXiiON

Search my nickname on eBay. I got all necessary bolts listed there with P/Ns.

Not 100% sure, but you can check around.

How many hours and how much did they charge you for the install?

First track day today with the new GT500 rotors on the rear. Worked great! Strong braking, no bias issues, and had zero fade at Limerock. I'm going to bleed them this weekend to make sure no bubbles, but the pedal feel was excellent through 25 minute sessions in 85F ambient temps.

So far, I am very very happy!!! I'll check out the brackets as well, but they seemed to hold up just fine

PJRManagement

mustang5o - I'm lucky, my local Ford dealer has a Performance Division, and they are amazing. I cannot divulge my price paid (I had to swear to them), but figure 3-4 hours labor, plus diff fluid and sealant.


dmichaels - I'm glad it worked well for your track day. I had my first track day with this new rear set-up on May 17, it held up very well. No fade, no scoring on the rear rotors, no burnt metal smell, no smoke. I think this is the right fix for the track.

mustang5o

So they don't want you to drum up business for them? Not that I'd be using them but still, seems like a stupid thing to ask. "Lets not advertise our great service and prices"

Glad to see it worked out well.
