take a look at the thread i started NEW WHEELS, and the thread black grill, you will see some of the work I have done, like we were talking about with the LM reps. I have a set of cargraphics being built. I am going to do carbon center with a step lip 20s. B. Gorman And myself have been working together and go to the wheel classifieds under B. Gormans page and scroll through to see some of the test stuff I did for him

Hey man. I took off the stock one in order to install the VRS diffuser. Use Plastic silicone to permanently bind the diffuser to the bumper. Then drill two holes on each side for two bolts to be bolted up for added security. Good luck man!

i just got the front lip and rear diffuser, VRS rear diffuser did you take off the old one first before adding the new one, and what did you use to install.
