The Brembo GT rear big brake kit for Mercedes SL55 AMG (2003–2008, excluding Black Series) replaces the rear braking components with a four-piston cast caliper and 380×28 mm two-piece slotted rotors Type-1 in red. This rear kit combines larger rotors and multi-piston calipers to increase braking authority and sustain consistent pad contact. Fitment is explicit for 2003–2008 SL55 AMG models except Black Series variants.
