No worries man. Was just a bad sequence of events at the end there as we were limited on bodies as well that week with a little something making its way through the ranks on campus.

Negative. Development is done but sway manufacturers themselves are still backed up well into 2022.

G20 M340i xDrive Fitment

Finally have confirmed M340i xDrive spring fitment and the original post has been updated to reflect this update.

Same drop as the RWD M340i (1" all the way around).

Apologize for the potato pics -- my SD card got corrupted somewhere along the way so only had a few dark cell phone shots to work with.

Looks good. Wonder if I would have problems running the 255/35/19 under there.

Does anyone have the Dinan springs on a M340 with the Adaptive M Suspension that can speak to how well the springs work in conjunction with the adaptive suspension? I'm considering going with the Dinan springs for my (on order) M340i xDrive but I live in the Mid West and the roads can be horrible.

Happy to report back that I am into 3rd week with Dinan springs on my M340ix with adaptive sus and I love it.

Ride feels a tad firmer across all the suspension modes but nothing dramatic.

Changed my view of lowering springs as I ain't got good experience with 034 springs on my previous Audi.

Good to hear. Can you post some pics showing the drop? Thanks

I know this was an old topic- but I'm on the fence about getting these springs because I want to make sure I won't have issues with longevity reliability alongside running the Dinan spacers.

Any insights from owners who have owned them for 20-50k miles?

Also, any personal installers in CT you would recommend? Haven't seen any shops specifically install these lowering springs and bump stops on a 21/22 M340i.

Upon trade in our M340i was at just shy of 30k miles and felt the same ride quality wise as the first day we installed the springs. Given, my opinion is likely biased. I have personally not heard any feedback from any long term use owners though so I will defer to them to chime in with their experience.

As far as CT shops -- Excelerate in Branford or The Shop in Norwalk are probably the 2 I would defer to personally but that is mainly due to having some extended interaction with them over the years. I am sure whomever the closest dealer is to you would be fine as well.

I have 15k miles of experience with my Dinan springs (without bumpstops - oops!) and the ride quality is the same as day one. Also running Macht Schnell spacers.

Does anyone have real life feedback/experience with the Dinan Monoballs?

I am about to place an order through my local shop, along with this and other goodies.

EDIT - I found the thread from 2021 with other commenting after installation.

I love Dinan!

Any update on the sway bars for RWD M340?

Nothing of any note unfortunately. For reasons I don't seem to grasp the sway bar stuff in general continues to move at an incredibly slow pace.

Maybe because of the ridiculous install
