The M Performance Parts catalogue includes 20-inch forged alloy rims for the latest 3-Series and 5-Series models, which the company says are 1kg (2.4 pounds) lighter per wheel than the same size standard wheel.
To improve braking performance, there is a Brembo big-brake kit with painted calipers in red, yellow or orange, and sports brake discs measuring 370 x 30 mm on the front axle and 345 x 24 mm on the rear axle.
For the six-cylinder turbocharged 335i and 535i sedans, BMW offers a sports exhaust system complete with two chrome-plated 80 mm tailpipes.
On the outside, the M Performance Parts catalogue includes high-gloss black kidney grilles and carbon fiber mirror caps for both the 3- and 5-Series models, racing stripes for the 3-Series, and a carbon fiber rear deck lid spoiler for the 5 Series sedan.
There is a variety of interior goodies such as a flat-bottom, motorsports-inspired, Alcantara steering wheel for the 3-Series, a seven piece carbon fiber and Alcantara interior trim set for both sedans, and a carbon fiber gear shift knob and selector lever for vehicles with manual or automatic transmissions.
BMW notes that all parts come with a factory warranty.
