RKP E9X M3 GT3 Carbon Undertray Splitter

Achieve the ultimate in aerodynamic performance with the RKP Carbon Front Undertray Splitter. Able to be fitted to any GT or GT3 spec front spoiler, this engineered under tray offers an efficient front splitter edge followed by a flat under panel reinforced with a balsa core wrapped in Carbon Kevlar. The result is a rigid and durable surface that can hold its own in any competition. Overheating won’t be a concern; air extraction ducts are maintained to allow for proper engine cooling. To go the extra mile, NACA style ducts extract turbulent air towards the wheels for efficient air movement out of the fender arches. What does this all add up to? A part that truly lives up to the hype.
