Specific Spacer Question

I am currently running this setup on a pre-LCI 2006 E90 330i ZSP.

Wheels: Vortex Tuning LM
F: 19x8.5 et 35 - 10mm H&R spacer --> et 25
R: 19x9.5 et 20 - 5mm spacer --> et 15

Rear fenders & rear bumper shaved/resealed
AC Schnitzer extended wheel locks
H&R Sport springs on sport suspension

Tires: Continental ExtremeContact DWS
R: 265/30/19
F: 235/35/19




I want to run a 12 or 15mm H&R spacer in the front due to Turner Motorsport's warning:

"A note about 10mm spacers: Any 10mm spacer is considered a custom fitment. The stock hubcentric lip on BMWs can stick out by as much as 11mm. This leaves a gap between the spacer and the hub which seriously compromises safety. We recommend using a larger spacer (12mm and larger do not have this issue) or check that the lip sticks out less than 10mm."

2 questions:

1) Will I rub significantly more in the front than I already do (front fenders not rolled) with a 12 or 15mm spacer compared to a 10mm?

2) Can someone who knows tell me the stock hub lip length of an E90 and if the car can or cannot fit a 10mm spacer properly because despite what Turner says, I do not see a gap between the hub and spacer, nor do I feel any vibration whatsoever.

Thanks in advance!

The lip is ~10mm. If you don't see it protruding, then it's not a problem.
12-15mm would be 2-5mm more. Do the math. Take a ruler and see.
The only way to prevent rubbing is to roll the fenders. Just do it.
I run 9.5" et19 front and do not rub at all.

Wouldn't it be easier and be more staggered if you just ran 35 et with the 20 et rear? Sure you're not super flush but I'm sure it more functional.... Zero rubbing.
