Evo Brakes

[m3f_f1nutter25]

hey, i have done a little research and found that the Evo has larger brakes, in the anticipation of a little power upgrade in my 3.0 euro i was thinking of upgrading to evo brakes.



is it as simple as a disc and pad swap or will i need to source the calipers or hub also? has anyone done this, i have seen a set of front hubs with discs and pads for around £100 but do not want the hassle of disconnecting the brake fluid lines etc is it as simple as i think, change disc and pads only? :beer:

How much more power are you planning on making? Your car is still among the best braking cars on the road today; to render your brakes inadequate would take one serious upgrade.

The later European E36 M3 brakes were taken from the E34 (?) M5 parts bin. You'll need the whole kit for the swap, but the money could be better spent elsewhere.

ok thanks, going to slap myself silly a little and spend the money elsewhere, thanks for keeping me sane!!

The E34 M5 pretty much used the same caliper as the US M3. The piston sizes were 60mm and both used the same rotor 315mm x 28mm. So, the M5 brakes were not an upgrade. In fact, the E36 M3, E34 M5, and the E32 750 used the same size front calipers and pads. They all differed in the rear calipers to account for brake bias in each car's design.



Now, the only upgrade would be to use the M5 Nurburgring package brakes which utilized 4-piston calipers and rotor size of 345mm x 32mm. However, IIRC there might need to be some mods to get them to fit - there was a thread some time ago on somebody attempting to do this upgrade.

Some 850csi and some e34 540i sports (or whatever the package was called) also had the 4 pots :thumbsup:

I only addressed the E34 due to his original post and did notmention the E31. Yes, you are correct about the E31 8 series with 4-piston calipers - it was only the 840i, 840ci, and 850ci that had them. The US 850csi had the single piston floating caliper, whereas the Euro 850csi had the 4-piston caliper. The E31 calipers were manufactured by Brembo and the E34 calipers were manufactured by ATE.



The US E34 M5 3.6 and 540i sports all used the single 60mm floating caliper. The Nurburgring package was the only offering of the 4 piston caliper along with other suspension upgrades - it was only offered on the Euro 3.8 model.

Hmm I was certain from my e34 days that the european "M 540i" (basically a 540i with an M package, much like the m-tech packages the e30 and e36's had) had the 4 piston calipers. Guess they were just larger than normal single pot's.

The Canadian M540 (only 32 made) hade the four piston calipers with the 345 x 32 floating rotors. My earlier post stated it was only offered on the Euro M5, but as it turns out - on the Canadian M540 model as well. The Canadian cars only lacked the Euro 3.8 motor - everything else was the same as you stated.
