Love it!! Wish it didnt come with such a hefty price tag compared to others.

Yeah custom Euro LCI tails, got it from a member on this forum who had a show car. Has amber turn LEDs as well. Blacked out just a tiny bit, matches the Melbourne Red and black trim pretty nicely.

Thanks man! Well worth it IMO, matches well with the Dinmann side skirts and Mode Carbon lip. Flows very well with the lines of the car.

That looks awesome. I have a Challenge diffuser but didn't think the Fancywide would fit. Did you have to modify the Fancywide to fit? Do you have any other pics of how the two fit together?

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!

How is fitment? Any issues with just using double sided tape?

Looks like it extends past the middle bumper piece on both sides, near the exhaust tips?

i noticed that also...seems that the e92 m3 rear bumper runs straight across between the exhaust tips, with no dropdown like the e90.

It does, but doesn’t touch the tips. I could have trimmed it down with a dremel but likely would have made it look worse. I suppose you could use a heat gun to try and bend the corners up closer to the bumper but I didn’t bother. I used plenty of black double sided tape (this is key as white tape could be visible near the edges) and it’s firmly on there, no need to bolt it in.

Call me crazy but I actually think no diffuser is best.

Agreed. I haven't seen any diffuser that doesn't mess up the lines of the rear end. None seems to integrate well.

I'm using the Varis style diffuser. They way it's installed right now it's hanging lower than most people run it. Might adjust it to be flush later.

Been looking casually at rear diffuser for quite some time, some really looks nice in my eyes. However, your picture reminds about the fact that one doesn't have to feel ashamed with the bare butt either… damn it's a nice one you have right there!

Can't take credit! Not mine but one of my favorite pics I have saved from this forum. I think the car has Akra exhaust, which those tips look great on a stock rear bumper.

Is the JL motoring GTS diffuser a 1x1 weave?

I'm pretty sure it was a 2x2 weave, but I don't have the car anymore so I can't check.

Who makes this diffuser rep?

I bought it from ABSautobody in on instagram. I now run the authentic varis though. Installation on either is a total PITA, fair warning.

would love to see a photo of a white E90 with the RKP rear diffuser

The closest one I like is the JL-Motoring Type II CF diffuser is the closest to the Challenge/RKP ones with an extra line in the middle for $450.

I asked IND for some photos of the RKP rear diffuser on white E90 M3

i do like the center part of the RKP with just 2 fins over the 3 fin style
but i feel like something is missing on the sides

still searching
