Looks great. Know of any Challenge rep diffusers?

Agreed! The Challenge/RKP one looks nicer IMO than the rest. Shame no one makes a sub $500 version of it.

Yeah, the simpler look of the RKP has a more pleasing look. The third fin on the other one adds too much detail that takes little space on the E90's big butt

I don't have the heart to spend that kind of money.

With how much some of these diffusers are I'm just planning on saving up for a varis lower diffuser and call it a day.

The challenge diffuser is the best ever. I'd drive my car off a cliff if I didn't have one.

Lol...I kid.

Anybody running this diffuser? Any feedback on fitment/quality?

Debating on purchasing this on eBay vs spending the extra money on a JL Motoring piece, which is also a 3D style. ($290 vs $495)

I had these. Not a perfect fitment. I would say around 7/10 when it comes to fitment.

My favorite thus far that is still available is the dinmann with the side pieces

https://www.dinmann.com/products/car...ser-bmw-e90-m3

Second would be the RPK

Ultimate fav is the non obtainable 3F diffuser

Yup I have to agree with Dinmann. Really adds presence to the rear end. Especially with a coupe exhaust. Here's mine with the diffuser rear extensions painted jet black with a E93 (my old car) Corsa with custom tips. Getting cans painted soon.

For those interested in the Metak diffuser, I just installed it on my E90. I've seen previously where people made custom brackets to install it since the bolts don't line up properly as it's designed for the E92. I elected to just mount it directly to the bumper with double sided tape, the piece weighs 1lb or less. The only issue with that is covering up the bolts, so I had to drill a couple holes in the fins from the bottom (would never be noticeable unless looking underneath the car) so that those bolts could be accessed in the future. Pics will show what I mean, let me know your thoughts!
