First, welcome to Rennlist.

The offset for those years was 65mm front and back with 225/50-16 tires on 7" wheels.
As per "The 928 Registry".

What are the size and offset of the Boxter wheels you're looking at?

Hi....thanks for your help, I am trying to get some 19" twisted model like the boxter ones...now if the boxter fits the 928 I will get used ones but I need to know if Boxter twisted wheels fit 928, I think yes, but in case mounting twisted 19" I need to know the offset in order to buy them...

19 inch wheels are a bit large. I would go for a set of 18's so you have some form of a sidewall on the tires.

And yes, boxster wheels are a very common upgrade so you should have no problems fitting them.

There's a mega-page wheel thread in this forum that will show you tons of Porsche and non-Porsche wheels fitted to various years of the 928. Looking through that thread, the 19s look a little too big in my opinion - the 18s look just perfect and will clear Big Black or Big Red calipers if you ever want to upgrade your brakes. Correct Offset is very important on the 928 for steering geometry.
