I'm helping a friend get rid of his pristine K-Speed (model - Speed) 18" x 7.5" with a PCD of 114.3 (5 holes). Taken off his RX-8 after just a short stint, he's upgraded to a 20" since.
Accompanied by 4pcs of Hankook Ventus HRII rubber. Man, these rims would look "ponna" excellent on a VIP-styled ride ;)
Tyre size is 235/40/18 (as seen in first pic). There's still a fair bit of rubber remaining.
