F80 Dilemma: does ours go to 11?

[ellipsis212]

Hi guys, I'm stuck in a decision making loop on wheels and the consequent tire choices for my 2017 M3 ZCP which is lowered on Swift springs.

Option1: 20x9.5 and 20x11.5 in which case I feel the need to run 255/30R20 front and 305/25R20 rear to keep tires in harmony with DSC. This is my preferred look based on other users' rides.

Option 2: 20x9.5 and 20x11 in which case I'd run 265/30R20 front and 295/30R20 rear.



I've already decided on PS4S tires for their performance but slightly fear the chunky sidewall as it relates to fitment. Can any of you share your experience and offer your recommendation? Did you go one route and then wish you had gone another after the fact? Thanks!

Phrased differently: does anyone regret choosing 11.5" rears?

Hey thanks for the reply. What make/model of tires are you using on those?

Best setup is 10 width on front and 11 width on rear, i have 11.5 HRE P101 with 295-30 and they looks a little bit stretched

I have 19x11.5 +44 rears with a 305/30/19...love it, 0 rubbing w/ swift springs (even under full load/compression), -2.15 rear camber

No regrets at all, we need all the tire we can get!

Thought I'd circle back on my own question and confirm my experience.

Running 20x11.5" rear with +40 offset and PS4S in 305/25R20 and I have experienced absolutely no rubbing. This is a great setup!

Shows the stance pretty well

I have 11.5 with et47 rear. Big mistake!












I should just go 12
