Gold calipers without ceramic brakes

[synclastica_86]

I would like to get the 6pot gold calipers fitted to am M4; however, I don't think I need the ceramic disks. Is this possible? If so, how much? I have been looking at preowned M4. I'm down to two cars, both in Austin Yellow. One car has the 6pot gold calipers but with no other MP components. The other car has all the MP components I wanted but only has the blue 4pot calipers. Hence, I would like to get the car that is better equipped and have the 6pot retrofitted. Having the entire carbon set fitted would be too pricey at $11,000.

I'm also curious bout this, would love the big 6pistons without needing ceramics

I think you can modify the M5 steel rotors to fit the carbon ceramic calipers, check out this thread http://f80.bimmerpost.com/forums/sho....php?t=1262633

How about the RacingBrake kit?

http://www.racingbrake.com/RB-Two-pi...-ca-p/2474.htm

[racingbrake]

Yes, in addition to shipping this standard brake size rotors with 6/4 pot gold calipers as an upgrade for those with standard brake, we also shipped iron rotor conversion kit for those come with CCB rotors

http://www.racingbrake.com/RB-Iron-T...bmw-irk-11.htm

If you are interested in CCB rotor sizes (400/380mm), gold calipers can be added to the kit for a 100% bolt-on kit.

RB offers more brake upgrade options than any other suppliers.

Our rear two piece rotors are OE emergency brake compatible - The only brake company offers this feature so you don't have to compromise or delete your rear emergency brake .

Check other brake upgrade offer from other brake company on this feature before you buy.

Is it possible to just get the gold calipers (both front and read) to use with the original M4 rotors? Are there any other parts that I need to get in order to use the 6 pot calipers? I want to do this because I prefer the cross drill look over the slotted look on the rotors. If so, how much would it cost to just get the calipers and associated parts required to install them?

The same idea has been well discussed in this thread.

There was a member claimed it can be done, although from our knowledge and understanding confirmed otherwise due to different rotor size between CCB and Iron rotors.

So basically if I get this set http://www.racingbrake.com/RB-Brake-...bmw-irp-04.htm everything will work? And are these just the calipers from the M5?

[racingbrake]

Yes, this kit is built for a 100% bolt on installation and has the best value in upgrading your standard iron brake to CCB "LOOK" w/o the fear and trouble in dealing with CCB and its expensive replacement* (see below).

These calipers are brand new from BMW dealer, same as those M3/M4 come with CCB brakes in gold color.

M3/M4 CCB front calipers are the same as M5 with Iron brakes, but in different mounting style and color (M5 is blue). The rear are totally different; M3/M4 CCB has fixed pistons 4 pot calipers while M5 is a small single piston floating caliper incorporated with parking brake.

Fits under 19" wheels with ample clearance and avoid your wheels from being scored.

No as there are no racetracks in Hong Kong, but I do enjoy spirited driving. On back roads, I do push the car to a point when the brakes begin to fade. Looks are also important. The stock 4/2 pot calipers looks too flimsy.

[dmk08]

So has anyone installed this RacingBrake caliper/steel rotor upgrade on their M4? Interested in them but not much real world info.

Umm...How can you claim this? Did you find a way to mount the OE gold calipers closer to the hub to add clearance between it and the wheel?

[md-370z]

agreed any real world feedback on these rb disc replacements?

[Zoli007]

Also, doesnt the master cylinder need to be changed? I know it is different in the CCB equipped cars. So if you change to those calipers, how will the brake pedal feel be affected if you dont change the master cylinder?

6/4 pot gold calipers:
Front 52.7 cm^2; Rear 24.6 cm^2
Total: 77.3 (68/32%)

4/2 pot blue calipers:
Front 50.3; Rear 25.1
Total: 75.4 cm^2 (67/33%)

Not only the total area, the front/rear bias are almost identical. So there is not a concern in this regard.

All RB brake kits are designed with the same consideration, even for these OE caliper swap kits.

Here is a track test comment about RB-CCM brake kit regarding the caliper design front and rear bias for a Porsche 993TT.

Got some reasonable sessions in the morning but afternoon was not much fun (too wet).
Brakes work nice! Slightly more pedal movement before brakes start to work. Need much less pedal pressures. Car slows down so quickly that it took all morning before I could start to figure out when and where to brake. I tend to brake early and do quite a bit of trail braking (to be easy on the brakes) and the car would slow down so much faster that I was scrubbing too much speed off. Just need more time to get used to it. ABS seems to work ok. There is some dust but not bad at all. The discs look barely broken in. The front/rear bias seems fine. I think eventually I should be able to brake quite a bit later.
The 19" wheels/tires work fine, slightly more harsh of a ride cf 18" as expected, not a problem at the track but more noticeable on the drive down over rough roads, running few psi lower pressures seem to help, not a big difference though. Was getting some understeer on the track, not sure if it was just because it was slick (wet/cold) or the wheels/tires/pressures. I had things figured out pretty well with the 18's, it's going to take a bit til I'm happy with these wheels.
Will get the car on the lift to inspect everything tomorrow.

My experience with RacingBrakes BBK on my E36 race car.
http://www.bimmerfest.com/forums/sho...19&postcount=6

Hey everyone, I'm Ian, the driver mentioned by RacingBrake above. This year I competed in the SCCA Runoffs, the National Championship for the club. In preparation for the event we upgraded the front brakes to RBs BBK and I couldn't have been more impressed, which is why I contacted them about working on a partnership for the Runoffs and upgrading the rear brakes.

As Scott mentioned, the rotors are phenomenal at dissipating heat. Daytona can be very tough on brakes with the number of high-speed braking zones (the bus stop/turn 7, and turn 1) where I go into braking between 145-155mph. With the stock setup, the bus stop puts so much heat into the rotors that turn 1 has diminished braking performance, but with the RB setup I didn't notice any of that. I used RBs pads, the XR70. Prior to the switch I used Hawk DTCs and I'll probably stay with the RB pads, the braking performance is comparable, probably a little better IMO with RB, and the modulation with the RB pads is certainly better for me which is where I see the largest improvement.

As for the question of number of pistons for the rear, I far preferred the 2-pot setup. The 4-pots just gave too much force for an FR layout even with some downforce in the back. Putting a bias adjustment in the E36 is a bit complicated due to the rules I have to follow in the Super Touring class and the ABS system. RB and I discussed this and they manufactured a 2-pot kit and overnighted it to me that day, I had it the next morning. They really went out of their way to help me and I was very impressed.

Really the only improvement I can see for the BBK would be set screws for the rotors to hold them still when the wheels are off the car, but due to the fact their kits fit on multiple models that may not be possible. If anyone has any questions about the RB pads or BBK I'll be happy to share any insight I might have, and I know RB will be more than happy to help as well.

If anyone is interested in watching the race, its available at https://www.scca.com/videos/1972510. I was really hoping for a podium finish but for a first appearance on a national circuit I'm very happy.

Lastly, here's the car coming through the International Hairpin (turn 3) at Daytona International Speedway during qualifying.

No it does not need to be change, I bought the CCB one and its identical just different part number..

You still have not answered my question. How does your kit eliminate the close clearance issue with the CCB calipers and 19" wheels? The only way this is possible is for the caliper to be mounted closer to the hub which means the disc diameter would have to be reduced as well.

edit: I think I see. The iron disc's you are selling with the gold calipers are 380mm vise the 400mm diameter that the CCB's rotors are. I am surprised that the gold calipers work on the smaller diameter rotor but that explains how you have the clearance.

[racingbrake]

380x36mm rotors with 6pot fold calipers are shipped.

To follow up on this – because i'm interested in the racingbrake kit – does the setup come with a shortened caliper mounting bracket?

The reason I ask: Just because the rotors are smaller in diameter, doesn't automatically move the calipers inboard, so want to be sure i'm understanding the clearance benefits fully.

Thanks In Advance!
