We have received inquires from GT3 members asking for iron rotor stock replacement and complete RB caliper kits for standard brake set up so that they can run 19" wheels and save tire replacement cost.

RacingBrake is pleased to announce the availability of the following set up:
The front calipers are made for direct mount to OE spindle w/o needing a spacer (identical to OE red calipers), while rear calipers will need a spacer (included in the kit.)

Rotor kits are ready to ship, the caliper kits has a 6-8 weeks leadtime as of now, but delivery will be confirmed upon order receipt. Contact us for pre-order incentive for caliper kits.

We know our 390mm rotor kit can fit some 19" aftermarket wheels but may not be all, while this 380mm rotor kit is for sure will fit ALL 19" wheels - You can also download the fitment chart under the description to check with your wheels.

More information and pictures will be added to this thread.

Below is the brake upgrade matrix for 991 GT3:



Thank you for reading.

Front Kit (380x34mm w/RB 6-pot caliper):

Front Pad: FMSI# D1666 (Same as Mustang GT500 Front w/Brembo 6-pot caliper)



Rear Pad: FMSI# D968/D1383 (Same as Nissan GT-R rear w/Brembo 4-pot calper)



These pads are standard FMSI#, not only we offer different compounds for street (ET), track (XT) and racing (XR), there are plenty of choice from other pad suppliers at much lower cost than OE pads or from Pagid.

RB makes OE replacement two piece rotor upgrade for both GT500 and GT-R. We are highly experienced in building this type of brakes for super muscle cars like GT3.

This looks nice, though I'm pretty sure the reason some 19" wheels don't fit is a lower control arm, not the brakes. That's true for PCCB, but not iron.

RacingBrake

The concern is whether our 390mm oversize rotor kit can fit under standard 19" wheels, not stock size 380mm kit.

The prime advantage of this 380mm RB rotor kit is the interchangeability with stock set up on rotor and caliper, also for those track goers the pad replacement will be much easier, less frequent, cost less and more choices on compounds because our calipers use standard FMSI pads than OE calipers' stock/Pagid pads.

Do you know these kits can also be installed onto GT3 comes with factory pccb, so you can run iron brakes and 19" wheels, a very good alternative to preserve your pccb and save you money plus more option/choice on your brake.

RB has complete brake options for your GT3:

• If you have standard brake - Step up to CCM (380/390/410mm)
  
  
• If you have pccb - Step down to Iron brakes (390/380mm)

What is the life time of CCM rotors compared to iron ones if used on track and do they need replacement or can they be reconditioned?

RacingBrake

We know RB iron rotors run by a GT-R driver (advanced level) can last for 17 track days on Arizona hot tracks.

As to how the CCM rotor life comparing to iron rotors, it depends on several variables, pccb (like ZR1) or CCM-X built by ST, the brake pad used etc.

So far we don't have yet one set of data for such a comparison but have been working with several GT-R and Corvette C6 ZR1 drivers, on both ST and ZR1 discs, against Pagid, Endless and EB pads, on RB and OE Corvette ZR1 calipers for a more comprehensive understanding on CCM brakes.

If you are interested you can follow these discussions in Heritage forums on the following topics.

You may want to fix your website info. Under "kit" it states that it come with 4 bottles of RBF600. Under the "choose options" it is automatically marked as 2 bottles.

"We know our 390mm rotor kit can fit some 19" aftermarket wheels"

1 Can you disclosure which 19" brand model fit with your 390 kits?

2 i see 380 and 410 , why a 394 kit?

Thanks

RacingBrake

Our 400mm rotor kit for GT-R was fitted to Finspeed's 19" wheel, it fits in although tight, but for sure 390mm kit we know s/b no problem.

Above is based on our customers' feedback than from the wheel suppliers. There are so many OE and aftermarket wheels out there, so the best bet is for you to download our fitment template and test on your wheels, or ask your favorite wheels company to check the fitment before you buy.

394mm is the CCM rotor kits using Corvette ZR1 discs as a lower cost CCM rotor kit than pccb full size kit (410mm) using ST discs.

All RB rotor kits regardless CCM or iron are made to OE offsets, so they can swap with OE rotors or calipers anytime you want - A very sensible and flexible alternative.

Thanks for the explanation

380 CCM are ST or ZR1 based?
Same question for 390 CCM thanks

RacingBrake

All RB/CCM rotor kits come with ST discs except 394x36 Front/380x34 Rear kits* that are ZR1 discs which are the same as pccb and Ferrari F430/458 by Brembo.

*Same set up are offered for:

• Ferrari F430 Scuderia and 458 CCM stock replacement by over-sizing the rear from 350 and 360mm (hand brake) respectively.

If it's possible to get the cost of reconditioning ceramic disks close to cost of replacing steel disks, I'd definitely get ceramics. But I cannot find enough info to do the math.
