1960-64 Front Disc Brakes Kit : The kit includes 2x 10 " cross drilled rotors, 2 hoses, 2 calipers, backing plates and hardware. comes with instructions, easy to install. You will need to machine your existing hub to accomodate the rotor. With this kit, you must use 14 inch to 17 inch wheels. Note: with this set-up, you cannot go back to 13" wheels. I run this set-up in my 64 Convertible with 17" wheels, and man, what a difference in braking and stopping. No more pumping and holding the steering, especially on rainy days ! You won't regret this investment! For any questions, don't hesitate to give a call at 018-753-2486. NOTE: This kit includes CROSS-DRILLED ROTORS, they WILL ALLOW BETTER COOLI NG AND PERFORMANCE.
