Rear Brembo Big Brake kit in the working

[dentprotony@gmail.com]

Hey fellas, my name is Tony, some of yall might actually know me from the x5m/e70/f15 forums. I offer custom brake kits for several bmw platforms as well as offer different solutions for a known BMW issues (driveshaft on f15, upgraded heat exchanger for F85 ). I am currently thinking to build a custom rear kit for am F10 m5 that would consist of a 4 piston 19z porsche caliper and a tesla epb caliper that would have an adapter and will work with your factory electric brake motor as normal operation. Kit would use factory rear brake rotor, would offer huge pad selection for the Porsche caliper, and would have a custom billet dual caliper bracket.
I had great success with the G05 rear kits, and currently working on G80 m3 rear kit as well as f90 m5 rear. So far it seems like everyone was extremely happy with the results/kits and both CNC craftsmanship and paint work were top notch.
My question is would yall think there would be a sufficient demand in this community for an upgrade like this ? If so i would need 1-2 people to test fit and maybe do a YouTube install for me, this would definitely reflect in the final cost ofcourse.
Please let me know if this would be something f10 m5 community would be interested in !

Looks interesting! What would be a price range for the final product?

I am not sure yet, hopefully will keep the kit in the 1400-1500 ballpark, thats billet dual caliper brackets, all 4 painted calipers, pads, epb adapters, braided brake lines, all the mounting hardware .

I would be interested.

What other supporting mods, coding or parts would this require? Do have estimates on the additional weight this would sacrifice?

///M models already come with coded brakes, so no coding would be necessary. As for the weight, kit is designed to use the stock rear rotor, factory caliper is steel, both brembo calipers are aluminum so likely 4 calipers will weigh close to the stock one. Brackets are billet aluminum so that weight will be minimal as well. Main thing is we keeping the stock rotor, so no rotational weight added 👍👍👍

Looks cool, I'd be interested

We went through complete fitting process already, now test kit is getting painted and will be out with the real life driving results in the next 1-1.5 weeks

sweet keep me updated!

What would be the key benefits of this 'upgrade'? Does the factory rear braking setup fall short in some way?

[M5_Raz]

Main thing for me would be looks. I saw a picture online of one a couple of years ago and it looks incredible. Check it out

Key features would be larger brake pad, monoblock vs floater caliper design, and ofcourse 🔥🔥🔥🔥 looks to match your front 6 piston caliper

Any movement on this setup?

Yes, first kit went out and was delivered yesterday, should have everything installed by the end of this week hopefully 👍👍👍

Sitting back watching and waiting

Do you want to test a rear brake kit for me? Please text me at 6016181023

Heres a little update, full kit (front and rears) is made in burnt copper oem cooor for amg/nissan gtr, install video is shot and will be released shortly!

For the Ceramic brakes owners: will such a setup also work for the delicate ceramic rotors on our cars? I would love such an upgrade, but I’m worried about putting diverse stress on the ceramic rotor and crack it 😥thanks.

Can you measure out your disc for me, diameter, thickness, offset, pad friction area, depth ? Thanks. Maybe i can come up with a kit for that as well

How will the larger calipers in the rear affect brake bias, especially during heavy braking and high speed trail braking? My loose understanding is that as brake bias moves rear-ward, especially on a lowered car, the rear end will be much prone to come out and or engage abs, both of which lead to less predictable braking behavior in high speed situations.

Very good point, factory f10 m5 rear caliper has 44mm piston , it is actually same as g80 new m3 caliper and we just went through these calculations on the m3 forums the other day, new kit 19z Porsche caliper has piston dia 31mm. To calculate total piston area you need to Caliper Piston Area = Pi x Piston Radius x Piston Radius x Number of Caliper Pistons on One Side. So stock would be 1520 , 19z caliper would be 1607 (3.14x16x16x2). Therefore difference is about 5%, which would be negligible given that the rear brakes only do 25% of braking and 30% in severe braking conditions. Keep in mind that 19z is a monoblock caliper, this would offer much more even/consistent pressure vs stock floater
