I haven't personally heard of them but I would be cautious with ebay companies.

I would say go for it, I can't imagine fitment being that terrible. When I finally have my rear mtech installed and have funds to get a carbon fiber rear diffuser I'm def getting a $300 ebay one instead of a $700 diffuser from the vendors.

I actually had the same thought as you when I picked up my performance diffuser from a local member. The fitment was so bad that I had to put in at least 4 hours of sanding down the extra material with the dremel. In my case it was worth it since I only paid $100. Then again I recall seeing someone on the forum get a cf one off eBay and the fit was good so I guess it's all about luck with some of these things coming from ebay.

Diffusers can be the most difficult aero parts to install and fit. Having a piece that is well built is very important. No need to spend $700. There are ones that cost far less that are a lot better quality than a cheap Ebay piece.

I am a firm believer that most diffusers for our cars are made in 1-2 different factories. I believe Vorsteiner makes theirs in house.

I ordered one from ebay yesterday that looks identical to some of the sponsors on the boards for over $200 less. couple that with the fact, if I had ordered one from a sponsor I would still have to wait for it to be made in Asia, it was a no brainer for me. I have been burned before with a diffuser from DD...never again.

I am all for buying from sponsors and I try to as much as possible, but $200+ in savings is too much difference IMHO.

Also, email the ebay company and ask if they can do better on price. My diffuser was $300 advertised price. I paid $250 shipped after I asked them...

I ordered mine yesterday...I already have a tracking number. Good luck

I got my diffuser from mod bar gains god what a mistake the exhaust cut r 3 inches away from actual exhaust n their teply was needs some modification lmao payed 599 what a piece of garbage fitment

if you gonna pay that much money, you don't need to go to ebay. There are a lot of vendors that sell diffusers for that price. Taking a risk and buying from ebay makes sense if the item is like $100

which vendors sell for that price?

roll_the_dice · 11-13-2014, 12:17 PM

Cheapest CF diffuser I saw anywhere for my e90 was the one I bought...$250 shipped. I have never seen a diffuser in CF for $100 unless it was used and cracked.

But as others have said...$599 for a diffuser from Mod bargain and it didnt fit. I would rather take my change for half the price.

RuthlessE92 · 11-13-2014, 12:31 PM

Which cf diffuser did you guys order off eBay? The regular mtech one or the performance one? I'm itching to buy but afraid of poor fitment

Spoolin Montego · 11-13-2014, 12:33 PM

I bought a dual performance one from RW for my girls 335i and it fit surprisingly well. Paid a whole lot less than 600.

If you are buying from an Ebay vendor from Taiwan, the fitment should be very good. All these forum vendors gets their stuff from Taiwan or China, since they are all made from there. You can find out which vendor is good/bad on the F30 Taiwan FB group page, they often post early reviews before the products hits the states.
