I verified the offset numbers on both my current set and the one coming. Here's what I've got using the offset calculator.
CURRENT STYLE 189 8X18, 225/40/18 OFFSET 34
NEXT STYLE 313 8X19, 225/35/19 OFFSET 29
DIFF 0.453 %. 5mm MORE clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 5mm
CURRENT STYLE 189 8.5X18, 255/35/18 OFFSET 37
NEXT STYLE 313 9X19, 255/30/19 OFFSET 40
DIFF -0.016 % 9mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 3mm
Do you think these numbers are ok, will not make the car look weird or affect the handling ?. I'll post pics and feedback once they are installed, can't wait !!!
Thank you all for any help you can provide.
The 313 for the e9x are 19x9 ET37 and 19x9 ET39, so the ones for the Z4 are 8mm for aggressive in the front, and 1mm less aggressiv ein the rear, but they will work on your e93.
