RB Brake Kit w/Brembo Calipers for BMW F80 M3/M4 under 18" Wheels

[racingbrake]

We are pleased to announce this track duty brake kit is now available:

Calipers:
Brembo OE gold 6 piston front
Brembo OE gold 4 piston rear

Rotors:
RB two piece rotors - 374x36mm front vs. OE 380x30
RB two piece rotors - 370x26mm rear vs. OE 370x24

These rotors have the same rotor rings as our two piece rotors for 740/750/550GT, readily available and they can comfortably fit under 18" wheels which are most desirable by track racers for the tire availability.

Adaptors are being made available by our local shop here in Anaheim here is the 3D design.



Kit Price? you can figure this out yourself.

Price of calipers - You know better than us, in fact I believe some members might already have them, and for those who have CCB brakes - Simply switch OE to RB adaptors and you are done.

Price of rotors will be very similar to those two piece rotors we offer for 7 series:
http://www.racingbrake.com/RB-Iron-R...bmw-irk-12.htm

Brembo Calipers - Stock (M3/M4)
Brake pads - Stock (M3/M4), or aftermarket.
Rotors - RB 2pc with rotor rings shareable with 740/750

It's not hard for you to realize the benefit and flexibility of running a brake kit with such a strong combination yet still can keep the kit within "stock" configuration, and you can save lots of money and hassle down the road than installing other aftermarket brake kits.

We also offer brake pads for OE calipers in 3 level of compounds:

XT910 - Performance street
XR70 - Track
XR90 - Competition

Another innovative brake upgrade proudly presented by RacingBrake.

This would be the most valuable track duty brake kit ever been offered, and we expect to start shipping them by end of April.

Front:


Rear:


Compare the brake pad size to standard brake (blue 4/2 calipers) and other aftermarket brake kits and realize how beefy they are - A true track duty iron horse.

Front is the same as M5 standard iron brake, the rear is the same as Nissan GTR rear and Brembo GT/F40 front/rear brake kits.

These are standard FMSI* pads - Not a special aftermarket caliper pads, very easy to find replacement for different compounds at low cost than non-FMSI pads.

• 2 ea OEM Brembo gold 6-pot calipers
• 2 ea OEM Brembo gold 4-pot calipers
• 2 ea RB front light weight track duty 2pc rotors (374x36)
• 2 ea RB rear light weight track duty 2pc rotors (370x26)
• 4 ea RB caliper adaptors (front and rear)
• 1 car set RB XT910 street performance brake pad
• 1 car set RB Stainless steel brake line

Isn't the booster different for the CCB? Won't there be an issue with pedal feel if we move up to the 6/4 pot combo?

[racingbrake]

You are basically swapping the original blue 4/2 pot to gold 6/4 pot calipers just like upgrading to other aftermarket brake kits. In other words, it shall not relate to CCB system.

For your information, here is the piston size and front/rear area ratio:

CCB (gold) brake calipers:

Front 6 pistons: 30/34/36mm = 52.7 cm^2 (68%)
Rear 4 pistons: 28/28mm = 24.6 cm^2 (32%)
Total: 77.4 cm^2

Iron (blue) brake calipers:

Front 4 pistons: 40/40mm = 50.3 cm^2 (67%)
Rear 2 pisotns: 40mm cm = 25.1 cm^2 (33%)
Total: 75.4 cm^2

Total piston area and F/R ratio are almost identical on both set up, so we see no reason to be even concerned on brake bias due to this upgrade, while it might be worthwhile for you to check aftermarket brake kits that you are considering before you purchase.

who has this kit and what do you think about it?
will other discs or pads be available if i would prefer them
like ferrodo or pagit...?

Please post photos of this kit on F8X cars with 18" wheels TIA

I see one problem with this, the calipers must be removed to effect pad changes. That is extra hassle to go from street pads to track pads and vice versa.

We've been using that RB 'progressive/incremental' kit on our M4 race car since the 2016 season and they've worked great. And it's very clever in the amount of flexibility you have as far as being able to upgrade one component of the system at a time.

RB rotors using the OEM calipers on our M4:



The really neat thing is that later, we were able to upgrade to their 6 pot caliper while keeping the same rotors.

I posted some that we've taken on our M4 race car on our build thread. You do have to be selective. With the OEM calipers, we were able to get the Apex Race Parts 18" EC-7 wheel over them, but not the ARC-8's. So you need an 18" wheel with good barrel clearance, but there are a number of the out there. I can look for better pictures, but we raced at Sonoma and Laguna Seca in 2016 with RB rotors and OEM calipers inside 18" Apex EC-7 wheels

There is a thread about racing pads for the OEM calipers and that was back in 2016. I know we were able to get some from CarboTech, but I think Cobalt Friction could make them. But now, in 2018, I would imagine you can get them from Hawk, Pagid, etc.

The RB 6-pot caliper that we're using is able to change pads thru the top. This is the caliper we were able to transition to from the OEM caliper while keeping the same rotor set from before.

I was commenting on the kit advertised which uses the OEM CCB gold rotors.

There are plenty of other kits that use non-OEM components where you can effect pad changes through the bridge area.

Yeah, even going back to our 135i in 2008 with the Brembo sourced front calipers, they were like that. Not sure why BMW spec'd them that way to Brembo.

Doesn't this photo show the stock caliper, not the 6 pot gold calipers that the kit includes?

[JamesGames]

racingbrake I assume you guys have calipers that fit the OEM rotors as well then? Is that an available option for someone that wants to retain OEM iron rotors and get larger 6 /4 piston calipers?

Yes, check out this thread on the RB 'progressive interchangeable' brake system
http://f80.bimmerpost.com/forums/sho....php?t=1486758

We've race on RB 6 pot calipers over OEM rotors - which fit inside 18" wheels.

That's true, but the wheel barrel clearance should be about the same. As shown in the post above, we have raced with RB 6 pot calipers over both OEM and RB rotors inside an 18" wheel.

I can let RB borrow one of our wheels for clearance checking.

Calipers (6/4) upgrade using stock one piece rotors which the front RB caliper kit #2384 (380x34) is compatible with OE rotors (380x30), but the rear is #2526 (380x28) same as CCM conversion, but not OE iron's 370x26 which they only have stock replacement but the adaptor can be made available so the stock 1pc rotor can use their 4 pot calipers.
