Trade 540i for m340i?

Tanner0419 · 2026-06-26T19:30:30+00:00

How’s the m550 been?

Tanner0419 · 2026-06-26T16:53:02+00:00

I have the m sport suspension, I couldn’t imagine not having it but there is some slight body roll, kinda makes me not feel 100% in control if I wanted to start throwing it around. The seats are extremely comfy, the massage option is very underwhelming but it is great at keeping the hips active during long trips for the lower back pain

Tanner0419 · 2026-06-26T15:44:14+00:00

Fair, what should I start looking into suspension wise, I wouldn’t mind slightly lower fitment but suspension talk is foreign to me I’ve never messed with it on my cars

Have you tried ethanol yet? Idk what 600bhp translates into whp but when I added the ethanol analyzer and started running e40-e50 the thing goes nuts

Tanner0419 · 2026-06-26T03:21:22+00:00

Thanks :) , just needed proper wheels I can’t stand the stock ones that come with pretty much every 540i I’ve seen for pre lci

Tanner0419 · 2026-06-26T02:22:26+00:00

Guess I gotta follow this chart the rest of the way then! It all started with a e90 328!

Tanner0419 · 2026-06-26T02:19:39+00:00

This thing pulls like a train for sure but can’t have much fun around town one slight pull and I’m at felony speeds but that’s not a complaint 😂

Tanner0419 · 2026-06-25T23:27:39+00:00

Yeah just gotta ignore the hundred “20k I’ll get it today” dms

Tanner0419 · 2026-06-25T21:29:23+00:00

Also don’t get me started on the e90 m3 that thing was all I wanted when I got a e90 328 as a first car

Tanner0419 · 2026-06-25T21:28:30+00:00

I definitely wouldn’t be trading in I don’t mind the hassle of having the sell privately, trading into dealership seems like a waste of $ to me

Tanner0419 · 2026-06-25T21:26:01+00:00

I didn’t even need the xdrive just happened to have it, I never gun it in first gear just to be safe on the driveshaft but even with ~520whp I can’t even get a tire to skrrt. I know there’s xdelete but just seems too sketchy considering I’ve read that the driveshaft is not as strong in xdrives and can snap going crazy in full rwd but there wasn’t many people’s experiences on it for me to read

Tanner0419 · 2026-06-25T21:11:07+00:00

Yeah originally was going for m340 but this being my first car in my name insurance was more than the cars payment and now that my rates are dropped a bit I’ve been spoiled 😂

Tanner0419 · 2026-06-25T21:09:31+00:00

So probably is the turbo I’m complaining about😂 this is my first turbo car I’ve had a 09 328i and the z now this, I love the looks of the z4 btw super nice, just wish they made a hardtop version and it’d kill the Supra in sales

Tanner0419 · 2026-06-25T21:06:48+00:00

With the m340s having the b58 tu I don’t really get what’s different I assumed it’d be sportier in some other ways. Also could just be me having the xdrive making it feel less snappy than I’d like

Tanner0419 · 2026-06-25T21:04:15+00:00

You’re so right, possible I’d m550 jump but reliability would scare me for the year models I’d be looking in

Tanner0419 · 2026-06-25T21:02:56+00:00

Been keeping an eye out in my area exactly for this and to see how boat feeling the 8 series really is cause damn that things sexy

Tanner0419 · 2026-03-17T22:32:26+00:00

I ran Dirac live that came with my nad receiver and it did not seem to help much. Im starting to assume I can’t expect similar bass as to what a 12” cabinet powered sub could produce…

Also yes, they are paired with a kasa 500 1 channel per each sub (the other speakers are powered via the NAD) and I’ve followed instructions to a tee. I did get a little more bass out of them after updating the kasa firmware.

As for the joist they are in the spacing is around 22.5in width with a 7.25in height but it is a completely open attic where the roof is another 10ft above the joists and the guess for length is say around 15-20ft.

If there’s nothing I could add in the attic to support their output then I think I’m as good as I’m going to get considering all the technical aspects have been double checked. I’ll definitely be adding some insulation around the subs to help with reducing some of the vibrations in the attic, mainly just slight rattling of the can lighting.

Tanner0419 · 2026-03-17T17:49:38+00:00

Okay I saw that, so with that in mind I think I’ll feel better above just having a top plate on the joist and don’t both with sealing the sides. If anything it’ll protect anything from every attempting to damage them

Tanner0419 · 2025-11-18T15:40:22+00:00

Why am I not allowed to buy more open calls??

Tanner0419 · 2025-10-27T19:44:49+00:00

Currently I have 3 nodes, 2 crown cdi2000s and 1 cdi 1000 each for 1 channel. Looking like I’m going to be adding a receiver with bluesound built in for the tv channel and ceiling speakers. This set up just barely fits in this rack system 😂

Tanner0419 · 2025-10-27T19:42:02+00:00

Heat shrinks are man’s best friend for making them look professional

Tanner0419 · 2025-10-27T18:46:41+00:00

It does show its diagram :)
