The Dinan springs look great. Are they compatible with the Adaptive Suspension on the xDrive?

Thanks for that information I'll also go with the alignment specs provided by Dinan after I put their spacers on. Surprisingly the alignment is still straight after installing the springs.

Has anyone of you guys with the Dinan springs (or any lowering springs) have to deal with ride height sensor recalibration? Local shop brought it up to me as part of a quote and I didn't know anything about it to argue it. I told them I'll take their price into consideration and get back to them.

This is the first I've heard of this. I had a local shop here in Orange County install my springs (European Auto Source) who are well versed with BMW's and they did not mention this to me. However, it is possible they just already know what to do and didn't even bring it to my attention.

Fair chance my local shop could be talking out of their ass as well. But still, I wanted to take all things into consideration. I know of the tilt sensor behind one of the front wheels. No clue if that tied into the auto headlight adjustment or if there's a separate system for that.

I have never heard anyone mention this (until now)

Well then. Guess I should check elsewhere then. Thanks for the input all!

Where did you find the Dinan alignment suggestions?

[FellowM3]

Anyone here install these springs themselves?

Kind of want to tackle this myself. Not sure if itll be too difficult.

Id be using my brother in law's lift.

If I remember correctly, they're on the instructions off the official product page on Dinan's site.

Kies did a video on installing springs on the M340. Not specifically the Dinan springs, but springs are springs in regard to the install process. Personally, I haven't done it but researched it a quite a bit. Even with watching the video, I probably won't be tackling the install myself out of fear of shooting a spring through my buddy's garage wall or worse. I've linked the video below:

On their website....here is the link

Speaking of alignment, just had my car in for service and gave them the Dinan specs. They tried but said they couldn't because had Dinan suspension and non oem wheels

Guess I go back to Carbahn to get it done.

Anyone do the Dinan springs, without Dinan bump-stops? How's the ride?

I didn't know about the bump stops until after my shop installed the springs, oops! The ride is slightly stiffer than OEM and handling did improve. I guess I'm not sure what I'm missing out on, since I do not have anything to compare it too.

I was in the same boat as you. You'd be missing some extra travel as you'd bottom out earlier on the stock bump stops vs Dinan's. It'll most likely result in the springs feeling like they're more aggressive than they really are.

I am looking into these myself, and have read as many threads as I can find on them, but still have a question for those of you on these Dinan springs.

I am new here, coming from a Q50. On the Q, it was always recommended to replace a lot of the stock suspension parts when you lowering, even a small amount (control arms, tie rod ends, end links, etc.) In reading through these threads, I am not seeing much, if any, conversation around this aspect. Is it just that there is enough adjustability in the stock suspension components that this is not necessary with the less aggressive Dinan drop?

I don't think there are many products out there right now to add adjustability to the G20 suspension. Vorshlag has camber plates: https://vorshlag-store.com/collectio...es-oem-perches I see there are some adjustable a90 suspension links, hoping they make the jump to the G20 at some point.

Agreed with the above response. Nothing is needed to replace or switch too when installing springs for this platform.
Installing front camber plates is recommended for the track or if want to optizime grip. But for most, totally unnecessary. I believe the only front camber plate option is from Vorshlag, as mentioned above.

Do you still bottom out on these springs and bump stops?

I think most people do not, unless in a very specific situation ie. I was traveling on the highway at about 68-70mph with a slight downhill gradient with a sharp angle at the bottom to return to a flat grade. That’s been the only time I have ever bottomed out.
PS. I run dinan springs without dinan bump stops.

Looks really good, but more importantly, the Dinan's ride well. I made the mistake of going H&R and they look nice, but lack comfort and if I am not going across smooth paved roads, the handling can become jittery.

Bumping this thread if anyone has more pics lowered on Dinan springs
