M340i G21

Aethelson · 01-20-2022, 09:14 AM

Hi,

I am thinking about how I can improve my car that will be delivered within a few months.

Splitter:
I think the best-looking one is M Performance Part so I will go for that one (https://www.bmw.de/de/shop/ls/dp/physical-goods/719882). I hope it also fits the G21 version. Do you have any experience with how durable the splitter is? I mean speed bumps, parking next to a curb or small stones. It is not much lower than the bumper, is it?

Diffuser:
It is not easy to find one for G21 and to fit with a trailer hitch. I found this one (https://www.bmw.de/de/shop/ls/dp/physical-goods/719914) but I don't want carbon fiber. Does anyone know the product number of this the same diffuser but in high gloss black?

Spoiler:
From what I see, there are only two options:
- M Performance (https://www.leebmann24.de/bmw-m-perf...2473006.html): I am not sure how it looks like but it seems too long. Does anyone have it and can show me some pictures?
- AC Schnitzer (https://www.ac-schnitzer.de/en/ac-sc...touring.html): this would be an alternative but I don't like the stickers on it (not sure if it can be removed).

I would appreciate any other ideas or insights.

Actually, this diffuser seems to be for the M340i version even though the tailpipe does not match https://www.leebmann24.de/bmw-m-perf...192455859.html

M performance kit BMW original...

G21 rearspoiler. Maxton design have one new right now.
Im interested in one.
But I prefer M performance. But its so expensive.

Do you please have any closer photo of that roof spoiler?
Also, the splitter looks really good - that's carbon, right?
I haven't heard about Maxton design before but they have some nice and cheap products. How's the quality?

Update:
I have purchased the rear bumper cover (https://www.leebmann24.de/bmw-m-perf...192455859.html) and rear diffuser (https://www.leebmann24.de/bmw-m-perf...192455821.html). The diffuser cannot be placed on the original bumper cover. It was pretty expensive at my BMW dealer as it cost around EUR 800 for both items.

The splitter was apparently only for G20 (not sure how the front differs between G20 and G21 but fair enough) so I will look for some alternatives that are also cheaper than EUR 900. Any suggestions?

As for the spoiler, I'll probably go for this, as suggested by Oxidgrey: https://maxtondesign.com/product-eng...21-M-Pack.html I am afraid it will look cheap but it is not too expensive to try it.
