wheel fitment
 

I am a new owner of an older Boxster looking for some help :
I have a 2000 Boxster I put 19 x 9.5 wheels on the rear ,had to use a 15 mm spacer to get it to fit however ,I still have a very slight rub on the inside of the rim on the E brake cable.Wondering if any one has any suggestions for a fix ??? advice
