RW Carbon

My 1x1 diffuser is almost ready for pickup - Will post pics once its installed.

Seems like the diffuser is the best fitment/weave etc.. they offer

I got the Vorsteiner style rear from RW Carbon. Customer service was on point with replies. Had a shop install it as I knew it would need someone with more capable hands than my own. They test fit it while I was still there and the fitment was harsh. When slipped in one side doesn't want to stay up, they had to have someone hold up one side hard enough that little cracks can be heard. Pull it back out, inspected, no damage found. The center fin also had to be sanded down because it was really close to the exhaust and might rattle.

I got the real Vorsteiner front lip from IND and installed it with a friend. No matter how many times or many ways we test fit it, the holes were half an inch off. We had to drill a hole and used a metal clip to make it stay.

Conclusion: I'd do business again with RW for the price. I just accept the risk of going aftermarket that it will never be real OEM fitment.

Where did you guys order the RW Carbon rear diffuser?? (factory the M performance replica one) What deal / or cost did you manage to get? And lastly how long until it came in/was shipped to your door? I want to order this thing asap but am looking toward where to get the best deal on this and quick delivery. One can order similar ones off ebay very cheap but it seems they're all from Chinese companies and the potential shipping waits/delays (1 month+?) are unappealing to me...

Start by googling their website... Also if you look under vendor section of the forum they are located there and if you contact them they may give you a better deal than on their website

I got a used Vorsteiner Rear diffuser and turns out the fitment on the real thing is quite terrible as well. Thank goodness I didn't pay full price. In fact yours looks like it fits better than mine did.

I think I'm going to get the rkp diffuser rep been torn between getting the original for 1069 or the rep from rw Carbon for 649.00

[lsturbointeg]

unbelievable that going with an authentic Vorsteiner diffuser that you had fitment issues. i mean maybe minor but not like what you mentioned and for the money?

So finally got my car and installed the 1x1 diffuser I had ordered and the fitment and weave are great. Here are some pics for those who are on the fence about getting it.

Did you get the rep or the real rkp diffuser? I just got mine last week and sent it back do to a lot of weave issues and the center fin wasn't the same length as the outer fins, which compared to my friends rkp diffuser we figured out they were the same length it's just the diffuser was bowed. This was supposed to be 2x2 but we're the fins are they went down to a 1x1.

I also got the RKP real one
I highly recommend getting the real one..I can't speak on behalf of RW carbon, but mine was a perfect fitment, just like OEM. The boys at Supreme power literally put it in within 5-10 mins tops...absolutely perfect

pics after install

Did your kick sensor stopped to work after this or it is working still?
it looks real nice by the way

I have the same one... not only does it work, it's so effing sensitive that when I close the trunk it reopens the trunk immediately

Combined with some other cosmetic issues I'm not too impressed with it, but I'll just accept it due to the cost.

Now the front lip is a completely different story. Looks great!

I got the rw carbon rep, aka CNAutoFans and am happy as a pig in shit

RW Carbon products are solid. OEM fitment and no plastic backing, just 100% beautifully weaved CF parts. I got their diffuser on my X5M, sure they are RKP replicas but my wallet is happy as hell (1/3 the cost).

Is yours the RW Carbon Fiber Big Fin Diffuser with 2x2 weave?

Also, can you confirm whether your trunk kick sensor works or not with this diffuser.
Thanks
