Challenge GTS Carbon Brake Ducted Front Lip Spoiler


Inspired by the M3 GTS,GT4 and other professional motorsports cup cars, the GT3 carbon front lip was designed to perform on the track or street. Full carbon fiber construction ensures this piece will last the test of time and the elements offering great strength and rigidity. The Carbon brake ducts allow 3in hoses to be clamped around the reinforced aluminum couplers for maximum brake cooling on and off the circuit

- Full carbon composite construction by dry laid carbon and resin infusion.
- Integrated carbon fiber brake ducts with aluminum reinforcement.
- Uses OEM mounting locations, no drilling
- Increased front down force
- Weighs only 3.5 lbs!
- Designed and Made in the USA


Challenge GT3 Carbon/kevlar Undertray

The Carbon Undertray Splitter add on option can be fitted to any GT or GT3 spec front lip spoiler for the ultimate in front end aerodynamic performance on the circuit. Our 3D engineered under tray offers an efficient front splitter edge followed by a flat under panel reinforced with a balsa core wrapped in Carbon Kevlar. This creates not only a rigid surface, but a durable one that can take the punishment dished out in competition. Air extraction ducts are maintained to allow for proper engine cooling. NACA style ducts extract turbulant air towards the wheels for efficient air movement out of the fender arches.
