It's finally here: the new generation of G-Series M3 and M4 super sports cars has arrived. Both feature that controversial new front grille design and enough performance to get you away from hecklers who may laugh at the unusual design. However, instead of waiting for fervor over the new models to die down, BMW has already released M Performance parts to make the G8X M cars stand out even further. Among these parts are a new diffuser and a new exhaust layout. We originally thought that these changes would be reserved for a hardcore GTS variant, but now we see that the changes are available for the regular car.

The new exhaust system features valve control and is made from lightweight - and aurally stunning - titanium. As usual, sports suspension and brakes are also offered, with the latter being a coilover setup that allows owners to tweak ride height to their taste. There's also a whole host of carbon fiber parts, from a front splitter and canards to side skirts and a rear wing.

Interestingly, it seems that BMW's flirtation with forged carbon fiber - the material favored on the Lamborghini Huracan Performante - was brief, with the M Performance upgrades for these cars featuring the usual sort of weave.

Inside, there are special door sills, floor mats, dry matte carbon accents, and a new M Performance Pro steering wheel wrapped in Alcantara and leather with a blue center marker and M-color contrast stitching. You can also get a wheel made from just carbon and Alcantara, while available shift paddles also made from a type of carbon can make the driver feel like a proper racecar driver.

Of course, all of this would be incomplete without new wheels, and various staggered designs are on offer in 19/20-inch and 20/21-inch sizing. Decals like those offered for the M2 Competition are also available.
