Carbon rear diffuser
Hey guys i'm looking to get a carbon diffuser for my 14' coupe. I know that there are a lot of them out on the market but I can't decide which one to pull the trigger on. I don't mind spending more money for one that will have a much better fitment and quality. I'd appreciate if you could post which diffuser you have, where you bought it from, and how good the fitment and quality was. Thanks!
If budget is a non-issue, just go Mode and never look back. Otherwise, I’m perfectly happy with my JBspeed unit on my pfl. And his shipping is very fast and he’s basically always available.

Thanks for info, I was leaning towards Mode but the 4-6 week wait time has caused me to shop around. I got some decisions to make but I do like how the p31 mode looks, it's a good in between between big fin and my stock diffuser.

So before you pull the trigger, find a good quality one, as many on eBay will require a lot of tweaking to fit decently, or do not fit right at all. The old saying goes, you get what you pay for.

I would go with RW Carbon. They're based out of and stock the parts in CA ready to go, so no waiting. I believe that if there's a fitment issue, they'll take it back as well. I have their carbon trunk spoiler and fitment is a solid 9/10.

a lot of the cf diffuser they sell in "RW", "VFR" "JBspeed" "JLmotoring" etc etc, all look the same as those on ebay, but all with different price point, obviously those with a "Brand" demanding a higher price, so u really get what u pay for? or are they really different, that is a big question, i would say they are all made by the same mold in the same factory, then sold by different supplier in China to different distributor around the world, each with their own logo sticker on it and resell them for a higher margin to us.
