Aftermarket diffusers

Kaisah · 11-29-2019, 02:34 AM

Anyone got a recommendation of a good seller for a decent performance rear diffuser? For a 340i specifically so dual exit.

There are plenty on Ebay/Amazon around the £50/£60 mark, but has anyone actually bought one of these, and do they fit ok? If you have if you wouldnt mind linking your seller that would be appreciated

Ideally looking for a gloss black one but im not massivelt adverse to having a normal plastic one painted if the fit is good and its cheap enough.

Fast lane styling in Essex, either from their website or ebay shop.

Not aftermarket but I bought mine for the 340i from BlueBell BMW at Crewe genuine parts so no issue with the fit paid £210 delivered and did haggle a deal with the parts guy good saving on the retail price.

Only aftermarket one I bought was awful fit, well actually it didn't fit, so sent it back. I appreciate not all non OEM are the same.

I got mine off ebay, pre-painted in gloss black for £90, it's 2-3mm short, but not noticeable unless you're right up close to it.

You can always take a punt on an ebay one and return it if it doesn't fit.

Thanks, thats what I was looking for

Worth a punt for half/third of the price, especially if its pre-painted!

Any photos of it on your car?

SuperHamz · 11-29-2019, 11:02 AM

Probably not the best photo, but here you go:

I mistakenly ordered mine from Hong Kong so it took a few week to arrive but fitment was good.

I recommend Fast Lane Styling. Really happy with mine.

They do look decent but are not a million miles away from a genuine BMW one with discount. The eBay parts are much cheaper

quick delivery yet to fit it, if it dont ill returrn, they seem like a legit shop as they have another site mstyle if you google

this dont fit gutted, thecarbon finish is good but the screw holes dont match up and it dont clip in the middle and other side when you have one side clipped in.
i think i may save up for the genuine one

Is it far off? I heard you could heat it up slightly with a hair dryer to make it fit.. but would need to be pretty close to start with

OldGit21 · 12-01-2019, 09:26 AM

Have you tried the EBay DM-Autotiele site:

what_a_bimmer · 12-01-2019, 10:55 AM

Bought this one a while back.

https://www.ebay.co.uk/itm/GLOOS-BLA...0AAOSwCg9dSZBM

Not a good fit at all in terms of screw holes and clips, but just bit the bullet and shoe horned it in rather than return it.

I thought OEM would fit better than this. My non-OEM has that gap at the top right where the reflector is, I thought it was a pretty poor fit but it's exactly the same as your OEM one

I'm glad you're happy with your purchase, but clearly from other examples of people buying the genuine article, you don't always get what you pay for.

SantaEugence · 12-02-2019, 11:43 AM

Got mine from eBay for £70
https://rover.ebay.com/rover/0/0/0?m...2F264061253345
as above its ever so slightly too short (can't notice it when on unless you're on your knees) also the clip holes etc didn't quite line up. It looked like it was in place but actually most of the clips hadn't fully gone home.
In the end took the whole bumper off, so much easier got every single clip and screw in no problem. Wasn't a huge hassle getting the bumper off either so if you're struggling to get the clips in just do that. Considering it was massively less money than genuine and it's just a bit of matte plastic, I was happy to take the hit with more time for fitting

It's as near as a perfect fit, more of a shadow you can see there.

Keep your eye on EBay. I bagged a genuine one including EBay discount for under £200

Bit late, but closer pictures for ebay special. Apologies for dirty car, hopefully the weather holds up so I can get her washed this weekend.
