I'm wanting to drop my car to 585/590 vs the BMW recommended 595/600, and...

a.) I'd like to see other cars with this amount of drop
b.) I'd like to see if I can figure out how many adjustment threads are showing front and rear so I can get it close before adjusting (mostly for the rear)
c.) I'd like to know if you have any rubbing/regrets

2018 Street car, no track days.

Tire size is 255/35/19 & 275/35/19 with no camber adjustment.

well, you're running V3 - so they go lower than MPS? What ride height do KW recommend to keep the dampers in the middle of their stroke?

For the rest, what offset are the front wheels (including any spacers)?

255/35/19 at ET20 (so, just 9mm further out than stock) will - with Cup2s - rub the arch liners on an OG LCI - never mind a M2C, at 595mm.

You may need to significantly increase the front camber to compensate (so cylindrical springs and camber plates) to get clearance.

*There is a possibility that the increased camber at 285mm solves this. Let us know how you get on...

I'm currently on MPS at 595/600 with no rubbing.

BAN_M2C Ran a wider tire (71-R) in those sizes and is lower than 595/600 with no rubbing and no camber plates IIRC.

To be clear, it didn't rub at 595mm until I fitted 255/35/19 Cup2 on 8.5/19 ET20 763M Reps, so a taller tire that makes 245/35/19 MPSS on 9/19 ET29 look stretched...

255 on a 9 and 9mm further out will be the reason

8.5 - but yes.

Currently eyeing the M2 CS racing 10.5x18 (with the addition of spacers and a stud kit), and wondering what front geometry I'd need to run...

If you can afford it the best thing I did was to fit the negative camber hubs that add -0.5 degrees of camber. Much, much nicer than camber plates that for me gave significant amounts of NVH.

Loads of room et22 9.5 with negative camber hubs

By the way I am 595/595
