I have a full set of Continental extreme contact DR. These are only sold to track teams you can only buy these used. New are around 340$ a tire willing to let them go for 450$ local pick up preferred. I live in des planes il 60016. These tires are awesome used only 2 track days all tires have been properly scrubbed in and heat treated. Im also selling the stock 17's mounted or i am able to separate them. Looking to get 700$ for the tires with rims or for the rims separate for 300$ Pm, text, or call 8472392984.
