I bought these for my 2000 Boxster S, and never used them. There is only one *tiny* scratch on the rim face of one rear wheel, there is a picture below.
I put links instead of pictures because the pictures are HUGE, and I didn't want to have them inline in the post.
$500 (PRICE DROP), buyer pays shipping and Paypal fees.
