IMPRESSED with the fitment! August 18, 2015

I reached out to Eric @ RW Carbon for a BMW F30 performance style diffuser in polypropylene and he had one in stock, held it for me for over a week until I came to pick it up. I gotta say I was IMPRESSED with the fitment! I'd have to say it's 99% if not 100% fitment! I installed it in less than 10 minutes! All tabs held in place with ease and just a little push to get the holes aligned for the screws. Absolutely awesome product! You guys have restored my faith in aftermarket parts!
