RW/Mode are using the same diffusers and parts you find on ebay and aliexpress. This has been going on for years but people are finally catching on.
I used to own a C63 few years ago. I did the community a favor by buying three of the same diffusers. One from eBAY that was $150, one from RW that was $600 and one from Mode that was $900.
All three WERE THE SAME DIFFUSERS. The only difference was that RW had its in their own box but the diffuser was 1:1 identical to the ebay one. The Mode Carbon diffuser was also 1:1 identical to the others but it had a Mode Carbon sticker stamped in two places. Besides that there was ZERO difference.
Those companies were sponsors on the forum and they had my post removed and when I kept posting and calling them out I was IP banned for good.
Now I understood why these kids that were like 18-19 that owned these companies were living large they were making hundreds in profit over duping people and lying through their teeth. You'll notice the FB group for the M5 is run by RW and if you post any CF part that is not theirs the post "mysteriously" gets deleted and then if you complain they'll boot you from the group.
Its okay though sooner or later the whole community in every car scene will realize and they will go under just as many other types of these kind of "sham" companies do. Just a matter of time.
Always buy your aftermarket parts like these on eBay or Aliexpress these other companies are just drop shipping or at the very best using their own shipping/packaging for the same product.
