I will give you the same answer here as I did elsewhere....
for starters if the wheels are actually 4 X 100 bolt pattern they aren't going to work at all...seeing as how the P5 has a 5 bolt pattern that is 5 X 114.3
as for the offset you will need to ask the place selling the wheels...as most wheels are available in more than one offset you will just have to check and see....
as for YOUR car...if you are going to stay with the 7 inch wide wheel...ENSURE you are getting a minimum of a +45mm offset.
