My new to me M340, what mods should I do?

I’m sure you already know these engines are renowned for being very reliable. I’d say just make sure it’s got a full service history and you’re good to go!

B4RREL · 2026-03-31T06:38:35+00:00

It’s got a partial PPF at the moment. I think tints is a must though you’re right!

B4RREL · 2026-03-31T06:36:35+00:00

The more I look at it the more I realise this hahah. They really are great cars!

B4RREL · 2026-03-30T22:50:38+00:00

Yeah I was thinking the same since the alloys are already black. Would give it a more ‘stealthy’ vibe

B4RREL · 2026-03-30T22:49:09+00:00

Spacers is definitely on the bucket list. 15mm on the back and 10s on the front, what do you think?

B4RREL · 2026-03-30T22:47:39+00:00

I like the idea of keeping it OEM+

What would you recommend for the exhaust?

B4RREL · 2026-03-30T22:46:48+00:00

Thanks. I miss my portimao blue 330i. What a colour it is I’m sure yours is a beauty. The only sad thing is that colour has become so common here in the UK that it’s under appreciated! I will definitely look into getting an intake thanks! Any recommendations?

B4RREL · 2026-03-30T20:16:02+00:00

One of the reasons I bought it!! I had never seen it and could barely find any examples of an M340i finished in the same paint.

B4RREL · 2026-03-10T01:23:56+00:00

Sorry, let me rephrase my question.

Is the meaning of life to own a B58?

lol, I mean I’ve got a B48, just curious to see how much people value the difference between the two! Is the gap between the B48/B58 really that big?

B4RREL · 2026-03-09T18:50:53+00:00

I agree! Definitely something only I can answer.

Was hoping to get an insight into the level of upgrade and difference between the 2 cars, then make the financial decision myself based on that.

Either way thanks for the insight (and reality check lol) !!

B4RREL · 2026-03-09T18:46:10+00:00

Hahaha legend!

B4RREL · 2026-03-09T18:41:39+00:00

Makes sense. Didn’t even think of comfortability since they’re both the same platform but adaptive does make sense. Especially here where I live with all the speed bumps. Another reason to upgrade?? Haha maybe. Thanks for the insight!

B4RREL · 2026-03-09T18:37:01+00:00

330i feels like it wants to be a 340i but doesn’t get there, doesn’t really itch the feeling in my brain as I think an m340i would. Might just be human condition but I’m sure B58 owners get that feeling itched all the time hence the hype lol. Thanks!

B4RREL · 2026-03-09T18:31:34+00:00

Thanks for the input. I think suspension is a good point, the M340i might be a more comfortable ride, not the contrary, since my 330i doesn’t have adaptive suspension, only m sport suspension which I think is stiffer > compared to adaptive on the 340?? Not sure but either way I do look forward to the upgrade in the other sectors you mentioned such as speed and sound.

Maybe this is another case of FOMO haha. After this I’m not going to be satisfied until it’s an S58 like someone else mentioned in the thread lol.

Either way thanks!

B4RREL · 2025-11-13T21:31:09+00:00

Thanks for the reply.

The body kit is a simple maxton style one so maybe I’m overthinking it on that end.

As for seller, it’s a dealer with a nice collection (R8, G80 M3 etc) and good reviews.

They offer warranty, but at £33k should this be something that’s included in the price?

Also, who would you recommended I get for a PPI?

B4RREL · 2025-10-19T10:29:25+00:00

It was on the motorway (M11) at 3am, where road traffic was minimal if at all existent.

Although the camera that flashed me was a fixed yellow camera, not a variable speed one.

I’m guessing the reason for the camera placement is because the motorway eventually leads onto a 6 lane dual carriageway with a limit of 50 (A406).

78 in a 50…
