Customer Reviews

Based on 5 reviews

Product is good but fitment is terrible, needs a lot of work if you want it to look flush with the car, I had to take off the entire rear bumper do a whole process to get this thing to fit decent, but once it was on it does look great. Great product just terrible installation.

rear end looking better than ever!

the rear diffuser took about 10 working days to arrive which is way faste than i expected. the product itself is great quality, looks stunning and feels very lightweight. however this is such a big part that I needed a helping hand, so be warned its not easy to install by yrself. but the final result is 100% worth it and makes my m340i stand out from the crowd.

What a freaking beauty!

Just installed this beauty at a professional shop and it was so worth it. Took a few weeks to come in because it's custom made when u order it but they will keep u updated the whole way which I loved. Thank u vorteq carbon
