Keep me posted on what you decide!
Hey thanks I do try to do my homework first!

I completely agree with you on the squared setup being a bit more boring and staggered being more aesthetically pleasing.
With that said, this car is my daily so having the ability to rotate the tires is a plus.

After reading this thread again in its entirety (plus a few others) I understand that the HREs would be a lighter weight option (and they are gorgeous to boot) but I think the Vossens will be easier to keep clean.

At this point I'm pretty sure I've settled on the square 20x9 ET25 setup and am now considering two different tire size options (235/35R20 or 245/30R20) for the Michelin PS4S tires.
Any thoughts/pros/cons for either or both of these options? Right now I'm leaning towards the 235/35/20 option.

When compared to my current 225/40R19 (19x8 ET27) size:
20x9 ET25 235/35R20
  • +1.4% diameter
  • +4.95mm ride height
  • -4.95mm arch gap
20x9 ET25 245/30/20
  • -1.1% diameter
  • +3.8mm ride height
  • +3.8mm arch gap
I've also recently ordered the Dinan lowering springs along with the ride & handling kit (bump stops). When installed this should equate to a 1" drop F/R.

My final objective is to end up with a dropped/flush overall stance/fitment similar to this M340iX on Rohana RC10s. He's running H&R springs along with 15mm spacers all around.
I also think the fitment and stance on GD1981's M340i with Vossen HF-5s is absolutely perfect - also factoring in that he's RWD and has a staggered setup with 12mm/7mm spacers F/R.

I'm also concerned about making sure I have long enough lug bolts. I ordered two sets of 45mm lugs from Dinan but I'm not sure if they'll work with the Vossen wheels? Vossen also sells lugs but only in a 30mm length... Fitment Industries will include a set of lugs and/or locks but I'm not sure if they offer extended lengths.

All these unanswered questions and decisions still to be made...

Did you make your final wheel decision yet chubbiejones?
Final decision = Vossen HF5
