I need to know definitively if the following will fit on my 1998 boxster:

Front 987-362-136-00 18x8 57 ET with 235/40/18
Rear 987-362-138-00 18x9 43 ET with 265/40/18

The factory 18" tires for the 1998 are 225/40 and 265/35 respectively.

The wheels and tires I am contemplating are from a 2005 boxster S.

Looking for someone who has done this to confirm it will fit without spacers.

Thanks in advance.
