Are you asking if the Fikse Profil 5 wheels that are on the car in the picture fit? Or are you looking to widen the Fikse wheels? I have used 8.5" wheels with a 45mm offset many times on the 993. We also make the Profil 5 in an 8.5" 51mm offset.

 

I am asking about a completely different set of wheels from what is pictured. The 18s in the picture fit great (although, I am not 100% sure what the offset is), but may be looking to swap the fronts for something else.

Thank you for the repose! I do like hear from "The Source" that 8.5 ET45 is good to go!
