Has anyone out there put this on their Z. I have a 240z with awful bumpers, and the kit looks pretty nice, but I have some questions. For one, what is it made out of? How hard is it to install? Is it bolted on or bonded or both. Also, does the kit include the side skirts. My last question involves ground clearence. Right now I have a front air dam from motorsports. The thing is cracked in half from the previous owner scraping it. I have tokico shocks, so my car is about one inch lower than the average. Is the aero kit just as low as the front air dams? If so, I guess i will just have to be real careful.
