Affordable Brake Upgrade

E60 m5 Brake calipers bolt onto f10 spindles without any modification!
The e60 M5 use a 2 piston caliper and a bigger brake pads.
ALL F10 use a single piston caliper(excluding the m5)

All you need are f01 Front rotors + pads. They will bolt on and even clear stock 19" 351 M sport wheels.
The only thing is you need to pay attention where the wheel weighs are. If they are too close to the spoke of the wheel, It could scrape the caliper.

I'll upload picture shortly.

Its good to know but not sure what the benefit is since you can always easily upgrade to 550i/650i/750i front brakes or even 760i front brakes. The calipers and brake pads for the 760i are the same outer diameter as e60 m5 but has more surface area and a much bigger pad.

With the e60 brake calipers, I'd want to understand if any other module needs to be upgrades like the brake pump.

Have you tried putting the e60 rotor on it? That might be the only reason to attempt this conversion as the e60 m5/m6 rotors are cross drilled and two piece.

The 550I/650I/750I/ all use a single piston caliper.
The 760li is a nice option, but good luck finding the even being remotely cheap. The e60 m5 calipers can be had for roughly $250

Their is no need to upgrade the brake pump, Many people install f10 m5 calipers(which are 6 pistons) without any known issues.

The e60 m5 rotors do not work at all due to the offset of the center hub to the rotor is much different.

This is a great upgrade, More even pressure against the rotor could provide more contact area for the pads, meaning more braking force.


E60 M5 calipers use a dual Piston Caliper. Each piston is 42mm(84MM combined)
the Alpina is still a single piston 60mm piston. So the piston size alone is about 40% bigger.

Unfortunately another example of a failed education system

Two 42mm pistons have a combined surface area of 2771 square mm.

A single 60mm piston has a surface area of 2827 square mm.

They're essentially the same.

No need for the disrespect or attacks.

So why do the e60 m5 come standard with 2 piston calipers? Why are the e60 m5 brakes designed to stop the car at 180+ mph? Granted I know they have a different rotor.
I compared the size of the e60 m5 pads to the f01 pads, and they are bigger as well.

If I'm wrong, please educate me. Not trying to start a pissing match or a war among anyone, Just trying to help the community.

I currently have f01 brakes on my f10. Ive had the e60 m5 caliper laying around for a while and was experimenting.

Do some tests to compare brake fade. With some more data might be a viable upgrade

Number of brake Pistons are more marketing than performance. Nearly always the limiting factors in braking are tire grip, and size of rotor for repeated stops (heat rejection). Multiple pistions can help feel, but actual performance....

Also heavier calipers add unsprung weight..

So, the F01 750i brake pads actually have slightly more surface area than the M5 e60 brake pad. This is understandable as the 750 is bigger/heavier. However, as I mentioned earlier, the 760i or Alpina has even more impressive braking power due to even bigger surface area. I know ppl dis on rock auto but check out the measurements listed in the picture.

Left is 750i, middle is e60 M5, Right is 760i/Alpina

Nice find _des_! We're you able to do a brake test? Our cars are stop roughly around 110ft 60-0 stock.
http://www.edmunds.com/car-reviews/t...automatic.html

Tests have shown 112ft 60-0 for the e60 M5. https://www.edmunds.com/bmw/m5/2006/...st-specs1.html

Both cars weigh roughly the same. Wondering what your discoveries might be.

I went with Powerstop, around $470 on amazon. I have used these on my gs lexus, both fell smoother and stronger. I have had 2 wrapped rotors on mine, don't think the stock are very good.
