19” Rims

Post by Valebmw » Mon Jan 07, 2019 9:29 pm

Hi all,
I know this is a well covered subject and probably answered a lot of times but I need your help.
I currently have 19” wheels on my E85 Z4 (M sport suspension). Front ET35, Rear don’t know, 19x8,5” and 19x9,5”.
These are Vertini wheels and the rears have about 5” inox lip. I have a perfect flush look front and rear.
Now the question:
Will 19x8,5” ET35 front and 19x9,5” ET30 rear fit and have a flush look or will I need to go to ET40 for the rear? The new wheels are zperformance with slight concave shape.
IT IS IMPERATIVE to have a flush look and no sticking out of the fenders.
Appreciate your response.
Thank you

How hard have you tried to find out what part number your current rears are? That seems like the best way to figure out whether ET40 will work for you or not.

Even if you use a calculator you are still going to be guessing how flush they’ll look.

If its that "IMPERATIVE" why not take your rear off & look for the et number to compare with the et30 you have planned :roll:

The calculator tells you exactly the new wheel position in relation to your existing set up so its simple to see how flush /pokey they are.

He doesn’t know his existing setup.

Hi there and thank you for the replies. However, my current rear wheels have a 5,5 inch lip so this will also affect the offset compared to a no lip wheel. Isn’t that right?

No - the lip will be included in the width and ET calculation
