Yes, availability and cost of the f80 calipers would be a challenge for me, i am used to selling 1-2 brake sets a week per platform (f85/f10/e70(f15) etc. it would immediately affect my production because i buy 19z sets in bulk 6-7 full sets at a time hence i get a good price on them, this wont be the case for f80 units. Definitely let us know if you can make f80 caliper fit and post some pictures, thanks !

It can be done. At least for the carbon setup
I have zero info though besides that it's a g81 in the photo. I am also trying to find more on this |

That seems to be a gt4 caliper, same as used on m2 competition ccb , these calipers are made to work with 28mm rotor I believe , also see how far the pad sits on the disc, there gotto be a wider pad to use more rotor area im sure.

The f87 M2C 4-p caliper is identical to the f8x CCB 4-p caliper, correct? Trying to understand the pad options available for this caliper. |

Check rotor thickness that they are made to work with, they are significantly wider, might need spacers for pads. |

Also, you’re supposed to have existing caliper mounting brackets available for any caliper and any rotor (diameter, rotor offset and thickness) for any application. Most creators of retrofit kits don’t care, or don’t understand, the radial pad offset and maximizing swept area is important. There’s an extremely poorly designed kit (two actually) floating around on the e9x forum right now. From incorrect piston areas, to poor radial placement, to rotors hitting calipers…yet people buy these kits without asking basic questions such as where to purchase replacement rotors, what pad shapes/numbers are used and availability… |

If the g80 CCBs are identical to the f80 CCBs (I believe they’re identical in diameter) and the 1-p sliding caliper is the same as the one used with the iron brake setup. So the f80 4-p caliper has a ~19% smaller piston area than the g80 1-p sliding caliper. This shifts the g80 CCB brake bias forward to 67.6%.

The question is do we need ISTA to bleed the brakes? Or can we just use a motive bleeder? I heard you can’t bleed the g80/82 using the traditional 2 man method cuz it throws all sorts of code.

I was able to find time during good weather for the install. Here’s some pix!
PS: I was able to order ISweep 2000 for the rear 4-piston Brembos, so the pads match my front set!

Did anyone find out if this is working with CCB?
Need to ged rid of the 1-piston caliper really bad.

This morning my daughter helped me to foot-bleed the brakes, and I just went for my first full drive after my test movements.
THESE THINGS STOP YOU REALLY GOOD. When I slammed the brakes the front didn’t dive like usual, the braking feels balanced. It may be the new Dinan HAS that helped, but the stopping power feels great to me. I put new ISweep 2K pads in the rears, the fronts have them already and the stock rears did too before. This weekend I do RaceMotive MIR so the brakes will get good tests slowing me from rolls at 150-160MPH.
