I am considering to get a 135i with the M sports package, and realised that the brake size they have printed on their catalogue says "High-Performance brakes painted with BMW lettering with inner-vented 17" front and rear brake discs". Just wondering if it's really that big or was it just a typo? How does it compare to the BMW Performance Brakes: 34 11 0 443 865? (the ones with the yellow calipers) Also, what is the standard 135i size brakes, and how does that compare with the BMW Performance ones?

Thanks in Advance,
