I'm also looking to get some new wheels and am trying to understand what I will need to make the 788 M2 rims (Front: 19x9 29/Rear: 19x10 40) fit my stock Z4M (Front: 18x8 42/Rear 18x9 30).
Using this calculator (
https://www.1010tires.com/Tools/Whee...et-Calculator#), it seems they will poke out an extra 26mm in the front. My
inner clearance in the rear is reduced by 23mm. Will these numbers be a major issue with regular road use?
I'm limited in my knowledge here but tried to understand as much as I can before posting.
