Ok I have a full set of z1 2-piece slotted/drilled rotors f/s. They have less than 2000 miles on them, never tracked. They came off my z which is a weekend car with only 7300 miles on it, they are in great condition. Please email me for more pics
joeyo93@yahoo.com. They save 10lbs each in front and 5 lbs each in the rear, 30lbs total from the stock rotors. Price $850 prefer local sale for now
