Hello,I don't have a set of cup 1's for sale. Those are the correct sizes. You can also use Cup 1's from an RS America or a narrow body 964. You can use a small spacer to get the fitment you are looking for. I have a set of Fikse FM 10's for sale with Continental tires for $2,300 plus shipping. 17" fronts are 8" and rears are 9" that would fit your car. Also have a set of Cup I borbets that would fit your car but I think you are looking for Oem. Sorry for the delay in getting back to you. Work has been very busy
Regards,
