Specifications

• Application: Mercedes-Benz S63 / S65 (W221)
• Manufacturer part number: A1-170

Slotted rotor faces sweep gas and pad debris out of the contact patch, which helps the pad bite consistently as brake temperature climbs.

Fitment

Listed for the 2007-2013 Mercedes-Benz S63 and S65 on the W221 chassis. Confirm fitment by year, trim, and brake package before ordering, as large-chassis Mercedes models were sold with more than one front brake package.

GiroDisc builds replacement front discs for high-output luxury and performance cars where the factory front brake carries a heavy vehicle at speed. Slotting the face gives gas and pad material somewhere to go and helps the pad clear its surface on every rotation, which keeps friction more consistent through repeated hard stops.

Rotors should always be replaced in pairs across an axle so both sides wear evenly and the car brakes straight, and fresh pads are recommended whenever new discs go on so both surfaces bed in together.
