I have a set of 17s for sale - they will clear Brembos on a Track and fit any other model Z. I have almost-brand new tires (Nokian Hakkapiletta snows, excellent performance and not that noisy in the dry - they are NOT studded) mounted - maybe 2000 miles on the setup tops.
ASKING $750 shipped / $700 local OBO - PM or email me. Pictures available upon request, right now they are stored (inside) at a friend’s garage since I’m moving. Also - I have two extra almost new (sub-400-mile) Kumho ASX all-seasons that I will include for free to a local buyer.
