2013 gt500 6 piston brembos

[steveespo]

Heard back from Dean Martin at Rehagen, the GS cars are using brembo full race 6 pots not the stocker GT500, guess they are close enough to allow them to upgrade. They also are carrying a weight penalty for using the 15" setup vs 4 piston 14". He is going to try and get me info on the pad shape so I can cross reference the major pad makers for track/race compounds. The Bosch ABS is supposed to really help with the modulation on track. I will see how the car does with stock booster/ABS, don't really want to spend $10000 on brakes yet but wouldn't mind a $1200 improvement if you know what I mean. Will keep all updated.

Its probably very similar to the differences in the 4 piston race kit vs. the stock brembo. Probably thicker pads and easier to swap.

Yeah looking up the prices for the Bosch Motorsports ABS M4 (which is I'm assuming what is being used), you're looking at $7900 for that controller setup. Too rich for my blood!

 

[fun4me]

Would it be possible to pull all these parts off a wrecked '13 gt500?

Apparently the GS cars are running the full performance friction brake setup. Z54 calipers, pfc discs, and pfc carbon metallic pads.

Got mine GT500 setup yesterday and so far am impressed. I am also working hard with some vendor/friends to get the correct race pad shape for track use. These brakes are the real deal, I am expecting excellent performance and fade resistance lap after lap. Pad swept area is 33% larger than the OEM Brembos on our cars. Here are some pics;

steve, are you running the calipers on 14" rotors? the difference in those pad sizes is bigger than i thought

 

[19COBRA93]

That looks like a 14" rotor on the left, yes?

How is that going to work? Or, are you planning on running the OEM 15's on the right?

Yes sir that is Brembo 14" rotor on the left, I posted the pic as a comparison, will be running the OEM 15" blanks at least until a 2 pc comes out for the application. Pad has 33% more swept area, I found the correct pad shape to use for race pads as well, the Lexus IS F uses this exact caliper only on a 360mm rotor. Withe 15" (380mm) rotor about 1/4" of rotor won't be swept by those pads. Once again until there is a GT500 specific pad I will run Carbotechs made for the IS F.
These are really nice mono block caliper and the rotors are massive. For track performance they will definitely improve durability and consistency.

pretty freaking slick. Yet another thing to add to the wish list

 

[Scruffy]

Those are mighty tempting.

 

[Speedfreak]

Has anyone installed this on a '05 - '09 GT? Will this 6 pot setup affect the brake bias? I've got a '07 GT and am looking to get these brakes but I've read that the bias might be affected + replacement brake pads are hard to get...

 

[leviathon]

are those the 14" rotors with 6 piston calipers? or are they the stock 2013 gt500 brakes

Pics are of 14" rotor on the left and 15" on the right. 4 piston pad on top, 6 piston pad on the bottom. I am switching fully to the 15", 6 piston setup. Found a pad shape that is available in Carbotech, Ferodo and Hawk race compounds and 19" Pirelli slicks. Anyone looking for brembo 4 piston calipers aknd a brand new set of Brembo slotted rotors PM me.

me ^ how much?

ditto Ive got suspension stuff to trade!! haha
