Anybody have any experience with JJ motoring spoiler or diffusers ? I did a search but did not find anything. I really like the looks of this diffuser and spoiler combo but I am wondering about fit and finish.

Eh. Not great service, James there is flaky as ***. I bought my carbon intake from them, and never got all the parts. After some of them came trickling in multiple shipments, I just gave up, too difficult to deal with. There are better vendors to deal with, I like RWCarbon.

Kind of the same as BLKROKTs story. Ordered a 3 piece front lip from them. After week I emailed them about shipping confirmation and then they finally reached out and said they'd get right on it. Order shows up. Theres a second box inside the main box for 2 of the pieces which were empty. Had to email them again about it to get the other two pieces sent. Fitment was a bit off, I still have that lip sitting in my garage and put the Vath lip on instead. I like the look of their stuff on their website. I'd say if you do order from them you'll likely have to keep up on them to get everything. Email was their only point of contact when I dealt with them.

+1 my carbon fibre intake I ordered did not fit well. Outer bolt holes did not line up for me

Still looking for a decent carbon fibre diffuser in the same style as that one but I still dont know which one has good fit with oem like tabs and finish.

Mode carbon - Dont like the recess for the little logo and heard from others some dont fit well eitheir.

RW Carbon - Looks good but uses metal tabs you have to bend, seen from some reviews fit isnt bad?

What else is there for facelift thats big fin like the picture above that is best fit/quality as possible? I dont car about price I just want it to fit with no gaps, the carbon quality good as possible & plastic fitment tabs like oem diffuser.

This is really disappointing because I have looked at almost every diffuser on the market and I like the looks of that one best.


If I bought a diffuser who would you recommend that I take it to have it installed ? I was thinking maybe a body shop ??

BLKROKT

I would definitely take it to a specialist diffuser shop. It's really complicated, and if you don't get it just right, your car will blow up.



Seriously dude, read the DIYs and just take it on yourself. It's just about the easiest thing to do on these cars.

I have read where people had to take the bumper off to get the diffuser on so that is what made me think I might need a body shop.

you do it's not that hard though. there is a video on YouTube on a c300 but it's the same. I have the Rw Carbon diffuser it sucks to put on but it looks good there are not any metal tabs. Has the same style tabs the stock one has. However for me they did not stay in. Had to pop off bumper and put a screw through the tab to hold it. This was recommended by Rw not a botched job I did but it looks good. The diffusers are so stiff you have to take off bumper to get them to fit right.

The current diffuser I have now I got off of amazon and the fitment was perfect. Just popped right in. The only thing I had to come up with was fasteners and drill two holes so I could replace the bracket in the middle. MY previous big fin diffuser I got off of someone that bought theirs off of ebay(guessing from one of those taiwan carbon fiber companies) and that one to he had to take the bumper off to get it to fit flush.

Listen to this man. Rear bumper cover takes about 10min to take off. The RWCarbon pieces are really nice quality and thick, but that makes them difficult to install while the bumper is on the car. Besides, you really want to take the cover off anyway to get everything lined up right.

The tabs wont hold it on by themselves, and to get a perfect fit you may have to Dremmel the slot in the bumper cover a bit to get rid of the ridges that are there. I skipped screws and just used 3M black silicone caulk to glue it on. It's not going anywhere and looks great.

Have few products from them. Diffuser is held by several metal clips you bend into the bumper. I have one for my C350 and C63 Coupe. Fits well, and the C350 diffuser has been through several years of winter / salt / sand, etc. No wear on the diffuser. However, I stopped my business with them after they were sketchy AF with their carbon fibre side skirts i got for my c63. The fitment was awful for one side. It was clear that it looked like sh*t and even took pictures and messaged them over several months, trying to get a solid response. Finally they budged and said, they'd charge me $100 for the shipping of the new one and I'd have to ship the old one back. For whatever reason, I still installed the piece that was not a perfect fit, thinking in my flooded mind, that it would fit perfect if i bolted it on. Well, it didn't. If you're a perfectionist, yea, it's awful fitment..

I gave up on them. They respond maybe once every few emails. Customer service is awful.

Mind you, they did send me a free replacement for a piece on my carbon intake as it was rubbing under the hood and cracked, etc.. But the side skirts was the grand finale and got tired of their sh*t. I don't have time to play Find Waldo with them. Never, ever, going back to them. Sorry for the rant..
