E60 M5 brakes for E39 M5?

Exorcist · 9th December 2007, 22:21

I need to upgrade the brakes for my beast. I would be able to get almost new E60 M5 brakes for 'cheap', but how hard it is to fit them to E39 M5?

Atleast he has them installed: http://www.carpassion.com/de/usergarage.php?no=567

Have anyone done this?

why don't you ask the owner of the yellow M5 this question. Check the for sale section, that car is for sale now. he is the member of this board.

"I haven't done the work by myself, but the tuner was very quick... Did the whole thing like a normal brake job

I think you just need some adapters, but I don't see any @ my brakes... BUT you need bigger wheels. 19" because most of the 18" are too small on the inside

"

So anyone know better?
It seems to be an easy task...

Doesn't sound like it's worth the hassle to me. By the time that you (or whomever you are paying to do this work) are finished fabricating brackets for the E60 M5 calipers to fit the factory mounting points, you would have spent some pretty serious bucks on it. Then you have to buy wheels (19") to accommodate the new rotors that you have installed. And for what reason? When it comes to stopping the car, "cheap" generally doesn't exactly enter my mind in the list of adjectives for what I would want. But then again, expensive isn't at the top of my list either.

But what I can say is that UUC has developed a cost-friendly Big Brake Kit for the E39 M5 and 540i cars. Having spoken with him at length last week, I can attest to this statement. Even though I am not sure if it has been released yet. No, don't take the website's word for it either, because that hasn't been update for a while.

Aren't the E39 wheels hub centric anyway? So would it even be possible to use E60 M5 rotors on an E39 M5?

Hi there

As I worte in the PM, a tuner made that for me. I had the same decision like a lot of others here --> Get a Stoptech/Brembo/whatsoever or get the e60 system fitted. The e60 system is a LOT cheaper than a proper Brembo kit and the ultimate thing for me to do it this route -> e60 discs and pads are available everywhere and every BMW dealer can check it etc.

Best regards

Richard

BTW: The system DOES work superb

I only used the car for long distance trips with a lot of km in Germany, there's no fading anymore. I also made two trips to the Ring --> No problems again

Agreed. My perfect brake upgrade would include Stoptechs 355mm up front only, more aggressive pads and stainless lines all around, and cooling ducts in front. Should be lots cheaper than an E60 setup as you won't have to upgrade the wheels also.

One thing to keep in mind: If you change the brakes to the E60 setup, you will most likely have to do all 4 wheels as it's unlikely that the brake bias is correct only doing one end. If you change all 4, you should also check on your master cylinder as the piston size may be too small for the E60 calipers. If you don't change the master, your pedal will probably travel more than with the stock setup as the E39 master cylinder is not designed for the larger pistons in the E60 calipers.

lots of headaches avoided by just buying a properly engineered after market upgrade.
