These aero parts are pursued through aerodynamics and are based on racing designs. The kuhl racing aero parts are made from aero materials and can be selected from two grades: High Grade (HG) and Strong Grade (SG). Both of these grades are made of FRP materials. If HG and SG are pasted together with the cloth mat of fibre glass, the strength doubles. The front bumper features a large opening, which has reverse spindle shape and has deep distinctive vertical ducts both on the left and right. It makes the design aerodynamic.
On the front bumper, a ‘front under diffuser’ and ‘grill top mold’ can be added. The side step is 100mm large in depth and has a large duct that makes provides a three dimensional look. The combination of a side step diffuser and side steps, make a car appear wider and provides a racing look.
The rear bumper is up to 200mm deep and placement of a large duct provides an aggressive finish. Attachment of the rear bumper diffuser can build a more extreme racing style. As the rear underbody diffuser is designed aerodynamically, it provides high down force at high speeds. Original gt-r back fog lamp can be attached with the kuhl racing rear bumper.
