Avantis featuring Dunlop Disc Brakes up front (using 2 1/8" pistons) may buy our oversized units (italics) increasing the piston size to 2 1/4". This upgrade 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.
