Brembo 09.9257.41 Drilled+Slotted Rear Rotor 330mm for Mercedes CLK55/CLK63 AMG

Vehicle Fitment

• 2005-2006 Mercedes-Benz CLK55 AMG (W209, 5.4L V8, RWD, 2-Door Coupe/Cabriolet, Rear)
• 2007-2009 Mercedes-Benz CLK63 AMG (W209, 6.2L V8, RWD, 2-Door Coupe/Cabriolet, Rear)
• 2005-2007 Mercedes-Benz SLK55 AMG (R171, 5.4L V8, RWD, 2-Door Roadster, WITH 6-Piston Front Calipers, Rear)
• 2008-2010 Mercedes-Benz SLK55 AMG (R171, 5.4L V8, RWD, 2-Door Roadster, WITH AMG Performance Package Code P30, Rear)

Fitment Notes

• Rear axle position only - sold individually (1 rotor per unit); order 2 for a complete rear axle set
• SLK55 AMG fitment is specific to vehicles equipped with 6-piston front calipers (2005-2007) or the AMG Performance Package (Code P30) on 2008-2010 models - SLK55 AMG models with 4-piston front calipers and NO Performance Package use a different 300x22mm rear rotor
• Replaces OEM Mercedes-Benz Part# A1714230212 / 1714230212
• Brake rotors and pads should be replaced together for optimal braking performance and proper bed-in
• Pair with Brembo NAO/Ceramic or Low Met brake pad formulations for best results
• Backed by a 2-year Brembo limited warranty

Features

• Cross-drilled and slotted surface design - drilled holes dissipate heat and expelled gases; slots continuously clean the pad face and improve initial bite
• Brembo's patented Pillar Venting Technology (PVT) replaces traditional vanes with internal pillars for superior airflow and up to 40% greater resistance to thermal cracking
• Solvent-free UV coating protects the full rotor surface - including internal ventilation chambers - against corrosion for extended service life
• High carbon cast iron construction shortens cooling times and minimizes noise, vibration, and harshness (NVH)
• OE-equivalent fit - engineered to meet or exceed original Mercedes-Benz specifications
• Precision-balanced to strict tolerances for smooth, vibration-free braking straight out of the box
• ECE R-90 certified and ready to install - no surface prep required
• Includes fixing screw kit for complete, hassle-free installation

Product Description

The Brembo 09.9257.41 is a UV coated, cross-drilled and slotted vented rear brake rotor engineered as a direct OEM replacement for the 2005-2006 Mercedes-Benz CLK55 AMG, 2007-2009 CLK63 AMG, and select 2005-2010 Mercedes-Benz SLK55 AMG models. Built from high carbon cast iron with Brembo's patented Pillar Venting Technology (PVT), this rotor delivers up to 40% greater resistance to thermal cracking versus conventional vane designs - critical for the high heat demands of AMG V8 performance driving. The cross-drilled and slotted surface dissipates heat and gases efficiently while maintaining consistent pad contact and initial bite throughout the life of the rotor.

The full-surface solvent-free UV coating - applied to the braking surface, outer diameter, hub, and internal ventilation chambers - provides superior corrosion protection compared to standard uncoated rotors, keeping the rotor looking sharp and performing reliably over the long term. This is a genuine Brembo OE-equivalent part, the same brand that supplies braking systems to Mercedes-Benz from the factory. SLK55 AMG owners should verify their vehicle's caliper configuration before ordering - this rotor applies to 6-piston front caliper models and AMG Performance Package (P30) equipped variants only. Sold individually; two units required for a complete rear axle replacement.
