Diffuser comes in a gel coat finish which needs to be prepped and painted.
Eliminate back-up lamps.
Although it accomplishes the appropriate “Bling Bling” effect, it will also function as designed. If you have all the other necessary elements in place i.e., a proper floor feeder system, droop limits on the rear suspension, ability to adjust total center of pressure (splitter and rear wing), you will be further able to exploit this diffuser. It also has a side feed entry so you don't get the full suction peak at entry and the second peak is located at the rear axle. This is because the engine heat is managed down the center of the car and exits at the opening of the exhaust pipes. This precludes a full 'closed in' floor which would improve the efficiency of the diffuser.
