Underbody components such as front air dams, undertrays, and rear diffusers are essential for maximizing aerodynamic performance.

The APR Performance Front Air Dam integrates with the factory front bumper to:
- Reduce lift.
- Increase front-end stability.
- Improve high-speed cornering grip
This Front Air Dam includes two integrated brake cooling ducts (2.5" inner diameter). These cooling ducts can be used to attach cooling hoses (not included) that lead to the brake system for maximum braking consistency on the track.

This Front Air Dam also utilizes a built-in aerodynamic splitter design that creates a high-pressure region of air atop the protruding surface, further reducing lift and increasing net downforce.

***GTR airdam is designed for road course/circuit racing is and not meant for High Speed/ Top speed runs where the Car will see an extended duration of high speeds. Without the ducting properly closed off or ducted to brakes the front bumper and lower air dam holds a lot of built pressure resulting in damage to the air dam as well as the bumper and other components related to the front end mounting as there is nowhere for the built up air pressure to escape or evacuate.***
