"Recently went to RW Carbon's warehouse to pick up a R Style rear diffuser for my Mercedes W212. The guys over their are very nice and helped me with a handful of questions. There has been some controversy over RW Carbon's diffuser saying fitment gap was an issue. As any car part, one car is used to make a mold of the part and since tolerances on both the part supplier and of the rear bumper made by Mercedes vary ever so slightly; fitment issues would arise. This being said perfect fitment isn't impossible, just time consuming."
"I ordered front CF splitters for my E90 November 30th as part of their big sale. Eric from RW Carbon contacted me shortly after I had placed my order stating their inventory was wrong and they were actually all out of splitters. Instead of just refunding my money or trying to sell me something else, Eric offered to contact his factory to see if they would be able to send some out with his next shipment in a couple of weeks. Long story short, Eric said it would be about four weeks and my splitters arrived as advertised in 3."
"I finally got my BMW F80 M3 and installed the custom 1x1 performance style diffuser I had ordered from rw carbon and the fitment and weave are great. Here are some pictures for those who are on the fence about getting it."
"New carbon fiber Lip & Diffuser on my SLS by RW Carbon! First off, I must disclose I am not a "Carbon Fiber Guy". However, I had seen some pictures and reviews of the lip & diffuser by RW Carbon. I contacted Matt at and ran over to pick up my order. His customer service is great and, I was really excited to put these on the SLS. The results were OUTSTANDING! From the finish to the fit. FLAWLESS!"
"I've been looking at diffuser options for my F85 X5M, which aren't many. There's one at the time, which costs an arm and a leg so I contacted RW Carbon for their new diffuser and they delivered. This is made overseas with very tight quality control, not something you would see on eBay. RW is very particular on their manufacturing partner. The X5M/X6M diffuser by RW Carbon arrived in perfect condition. Every carbon fiber weave lines up, the clear coating is flawless, and the fitment is perfect. Best of all, it's made of 100% carbon fiber."
