Models using 1 3/4" pistons may buy our oversized piston units (italics) to increase the piston size used to 1 7/8". This change will allow the user to realize approximately 10-15% greater force on the brake rotor, decreasing the required brake pedal pressure during braking, and potentially shortening stopping distances.
