10j x 18 et40 boxster s

Hi guys,
About to pull the trigger on a set of oz alleggeritas. Rears are listed as 10x18 et40, the dealer doesn't list a 9x18.

I'm going to fit a 265/40 r18. Will I have any issues on my 987?

Appreciate the advice.

I cant speak to the fitment, you may need spacers for the rears but I am curious why you plan on running 265 on a 10 rim. Both 265 and 275 are streached on my 10 rim. I would go with a 285 rear 265 front, that will give you a flat sidewall.

Yes, you are absolutely right. I have found the correct offset 9x18 from larkspeed at a very good price for four wheels and they are now ordered.
