M340i Maxton rear diffuser

Bianchi Dave · 01-09-2023, 06:08 AM

Looking at diffuser options and came across this company. Its probably the nicest looking diffuser I've seen -

Anyone got one of these fitted, or any general feedback on Maxton quality?

When I had a Golf R, Maxton was very popular with owners.

Thanks. Quality looks good enough in photos, but with aftermarket stuff you never quite know what fitment will be like! I'm quite tempted by the front splitter too.

Nice. Personally I went with the F1 style diffuser, like the attached. Fitted well and looks quite aggressive.
Bought through Ebay

Thanks, a little too aggressive for me though. Just a pity the standard one is a bit boring, and MP one not much better IMO. The Maxton one is definitely the best I've seen, and a bonus its reasonably priced too.

Agree. I like the Maxton kits.

I received mine last week and hope to put it on this weekend (same as the original post pic). Will do some before and after shots.
I've also got the rear spoiler (M340 touring) but that was original BMW.

Will be very interested to see them

Matrixsenior · 01-11-2023, 11:25 AM

F1 a bit OTT for me. But each to their own, I have been looking for a diffuser and I like the Maxton one, going to see if they do one for the 330i.

Talisman77 · 01-11-2023, 12:39 PM

I'm not really an "aftermarket" guy, but that Maxton looks pretty smart to me actually!

I'm not a hands-on person and I think this rear diffuser looks fantastic, she's anyone have any recommendations on how I find someone to fit this for me please?

Jimbon1973 · 01-17-2023, 03:47 AM

Hi guys, so sorry but the weekend was too busy for me to even try.
To be honest, the diffuser kind of looks like it'll be a 10 min job (i always think that) so may try tomorrow during day- I'll 100% add some pics on here.
Just in the box it looks great.

seventen710 · 01-17-2023, 08:07 AM

I had a Maxton diffuser on a previous car (SEAT Leon ST). It was a very well made item and looked great. Would recommend.

haha no worries! A couple of during photos would come in handy too if thats ok, just to see where all the clips etc are, or if theres anything to watch out for. I've not ordered yet but even if I did I'd likely wait a few weeks to fit. Its struggling to get above freezing up here today and I'm always mindful of the potential for clips to break when they get more brittle in the cold. Could always get the hair dryer out I suppose!

what is textured version, is that just matte ?

Appears to be, going from the close ups on other products on their website. To me the gloss looks nicer, matches the black B pillar and shadowline window trim, even without the extra black shadow accents,

Jimbon1973 · 01-22-2023, 11:25 AM

Tried putting it on today, but realised that there's no gap for the tow hook
As per pic above, looks like I need to remove the bottom 3rd of my tow hook cover for it to fit.
Will have to check as I attempted in a bit of a rush!

I see what you mean. Quite a few other diffusers come with a little tab which gets swapped with the stock piece at bottom of tow eye cover I think, but the Maxton one appears to run straight across the bottom of the cover.
tbh probably looks cleaner that way. Nothing about it in the instructions?

Any updates of what you had to do to I stall it? I’m looking to buy this diffuser soon.

I'm hopefully fitting at my local detailers later today... provided we can get the original one off!
