I bought this new from mikes xs and paid around $165. I am selling it because I upgraded to brembo brake caliper and need a 320mm rotor disc. This is 298mm which with the spacers that are provided can be used with stock calipers 77-84. Many also use this size brake disc when upgrading to the blue dot calipers. It hasn’t been used very long and I don’t have a precision dial caliper but on mine the thickness is around 4.5mm with a minimum of 3.5mm. So still plenty of life left. Asking $110 plus shipping so if your in U.S. I will use usps flat rate.
