The Rear Diffuser for G42 2 Series & M240i delivers a confident and well-defined upgrade to the back of the car. BMW forms this diffuser from genuine prepreg carbon fibre, keeping the weave consistent so it matches the rest of the M Performance range. The gloss finish adds depth, and the fit feels secure because it follows the original mounting points without forcing changes to the bumper.
Owners who prefer a factory-plus look will appreciate how this diffuser fills the lower section with more structure. It settles around the exhaust area in a clean, natural way that suits the G42 shape. The lightweight construction holds its form over time, and the design helps guide airflow while keeping the rear end balanced.
For drivers who value OEM quality and want a rear upgrade that strengthens the car’s appearance without stepping outside BMW’s design language, this diffuser is a dependable choice.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.
- Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
- Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
- Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
- Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
