2012 Brake Upgrade
 

The rumor I've heard is that all of the brakes are getting shifted down the line. V6s will get current GT brakes, GTs will get the current GT500 Brembos, and 2012 GT500s will be getting a 10mm bigger rotor and Brembo package.

Can anyone confirm/deny or add to this?

It would be a welcome update if true. How much to pads & rotors cost for the current GT500's?

IIRC when the 350z first came out, the pads for the Brembo optioned cars were $200+ front and rear, and rotors were $150-$200ea.

I can say this, so far my source with Ford info has been 100% on the ball with what I've heard. It's mostly minor details that get passed on, but enough to keep me ahead of the game in terms of rumors.

If someone could comment on the current GT500 brake size (and GT for that matter) we could get some %'s in size increase for comparison.

07-10 GT500's have a 14" 4 piston setup...

Doing some math, the info I have shows:

Current GT500 = 370mm rotor = 14.56 inches
2012 GT500 = 380mm rotor = 14.96 inches

Rotor gains a half inch in diameter.

That would be very welcome, if a bit overdue. The current GT brakes seem to be adequate ... for about one or two hard stops only.

A 14.5" rotor is a nice chunk to stop on. From my experiences with the 13.5" rotors on my Speed6, they are more than adequate in stopping a 3600 lb. car over and over again when I autocross.

Autocross, maybe, but not on road courses, or even bombing down some mountain passes. While there are some road racers here that say all the stock GT setup needs is better pads, lines, and fluid, I think the added mass and swept area of the 14" upgrades is definitely worth it.

Sounds good. Now I gotta think about wheels that fit the current Brembo setup in an 18" size... any help?

I've heard the 18" GT4, FR500, and Steeda wheels do fine, as do the GT500 wheels themselves.

:agree: I replaced the woefully inadequate stock brakes on my (older) GT with a Cobra Brake Upgrade, stainless lines, and Motul fluid. What a difference...

I seem to remember reading (can't remember where now... getting too old) that the current brembo kit used on the GT500 doesn't have a very large selection of aftermarket pads. If the Gt were to get that set-up, it could serve to increase the selection. :nice:

Of course, if the stang weighed less.....:jester:

Yeah, but diets are expensive. Corvette Z51 to Z06, $20,000. Aluminum frame and composites don't come cheap. Neither does good engineering.

Still, weighs whole lot less than the competition, even competitive with the Z.

Guess this is going to mean that the wheel width is going to increase. If you go to the FRPP site to order the GT500 big brake kit, it tells you that the stock GT 18x8.5 wheels are not big enough for this kit. Need at least a 9 inch width or 9.5 like the GT500 stock wheels. This would be good since the extra power is going to necessitate wider rubber than 255.

It's not the wheel width that is the problem, but the design and where the wheel spokes are placed on the wheel.

The monoblock calipers of the GT500 brembo's are wider than the factory cast calipers on the GT's It's a matter of wheel design. You could get a 7" wide wheel on the car with the GT500 brembo brakes if the spokes where moved forward on the wheel enough.

Now, there's nothing inherently wrong with the GT brake package as it is. Going to the GT500 setup in thr front isn't going to reduce stopping distances. It's biggest upgrade point is it's ability to more efficiently soak heat which provides for more consistent stopping without fade.

Certainly, that's not a bad thing, but unless you're auto-crossing on r compound rubber, or open tracking, you're not going to see much benefit from it at all. Stickier rubber is going to provide the best stopping distance decrease. Even with a bone stock brake system.

My feeling is that I'd like to see somebody step up to the table and create a relocation bracket for the GT calipers that will allow them to accept the GT500 rotors.

This IMHO would be the best bang for the buck for anybody that does leisurely racing activities in a GT mustang. The added swept area will help at high speeds and the larger mass will provide a bit more efficiency for multiples of hard stops.

Isn't that basically what the Baer Decelerator kit is for, relocating the stock calipers?
(the cost is because of the expensive, lightweight rotors)

Yeah, just like that. Although for racing purposes I wouldn't want the cross-drilled and slotted rotors. It just reduces the disc mass, reducing it's heat efficiency, as well as creating areas prone to cracking.

That's the idea though.

It would take some serious track abuse to have an issue with the GT calipers. Even then, given their cost difference over the brembo mono-blocks, even if you did bend one due to clamping force, you're probably still ahead of the game money wise if you have to replace a set.

According to "The Insider," the upgraded brakes are coming out with the new powertrains and transmissions for MY 2011.

Someone stated, don't know for sure, that the Baer rotors are available plain or just slotted instead of drilled for those tracking the car. I think he got them through Stage3, if I recall.
