Boxster wheels
 

Hi
I’m new to a Boxster

I have wheels and I wanted to ask if someone could verify the hub specs

The wheels are 19x8.5 with a 56 offset and hub spec of 71.56.

I see 71.5 and 71.6 listed on sites but I’m wondering which is the exact spec for a 1999 regular Boxster base model.
Thank you for the help

What you call the "hub spec", I would call the "center bore" or "hub bore".

All of my usual references show the same variation that you found (some say 71.5, others say 71.6).

Since every other Porsche (911, 912, 930, 964, 993, 944, 968, 924, & 914) is typically listed as 71.5, I'd go with 71.5.
