For long mixedwet/dry track, I like Nitto NT-05
For all around daily... I really liked the AS3+

With a 285 tire, I wouldn't go with a 10.5. I'd drop down to a 10.

I "believe" the X5M uses the exact same sport brakes as the M50i... not 100% sure though. But I know they both use the electronic parking brake mechanism on the rear, and the el-cheapo cast single piston caliper..... which I hate.

I've been researching rear BBKs since day 1. Ksport makes one that re-uses the EPB. So does D2 racing. Neither brand I trust. I "believe" Brembo makes a set, but I haven't been able to find pictures/info yet. Still looking though.

For right now, I'm ok with stock brakes until something better comes along.
I don’t know about the rest but the discs are cross drilled on the M and are probably thicker for cooling.
