I modified the front bumper with matching black metal grills for the main radiator intake and two side intake ducts. The same metal grill material replaced the OEM non-functional rocker panel intake ducts, converting them into functional intake ducts. I plan to run silicone brake duct hose from the rocker panel intakes to the rear brake rotors. The rear bumper is being modified to replace the plastic diffuser parts on the lower part of the bumper with matching metal grills to redirect and dump air flowing under the car into the rear low-pressure "bubble".
The inspiration for the grills include the BMW Z4 and M3 ALMS and DTM cars.
