What is the main benefit of the slotted design on these rotors?

The slots on the rotor surface help to vent heat, dust, and gases that build up during braking. This allows the brake pads to maintain better contact with the rotor, resulting in a more consistent and powerful braking performance, especially during repeated hard stops.

Do these rotors come with any hardware or are they a direct bolt-on replacement?

These GiroDisc rotors are designed as a direct fit replacement for your factory rear rotors. They are precision-machined to bolt directly onto your existing hub assembly without requiring modifications. It is recommended to check the manufacturer's installation guide for any specific hardware or torque specifications.

What type of brake pads are recommended for use with these slotted rotors?

While these rotors are designed to work with various brake pads, they are particularly beneficial when paired with performance-oriented brake pads. For optimal results, consider using pads that are designed to handle higher temperatures and provide consistent friction, especially if you engage in spirited driving or track use.

Product Details

These GiroDisc slotted rear rotors are made specifically for your 2012-2017 Mercedes-Benz SL63, excluding models with the Carbon Ceramic Matrix (CCM) braking system. If you're looking to improve your braking performance, especially under demanding conditions, these rotors are a solid choice. They are designed to work with your existing brake system, offering a direct replacement for your factory rotors but with notable enhancements.

What sets these rotors apart is their construction and design. They are precision-machined from a high-carbon, high-strength iron alloy, which is known for its durability and ability to withstand heat. The slots machined into the rotor surface are not just for looks; they serve a critical function. As the brake pads heat up and wear, they release gases and dust. These slots help to vent these gases and dust away from the pad surface, which means you get a more consistent and powerful bite from your brakes, even during repeated hard stops. This improved pad contact also helps to keep the rotor surface cleaner, reducing the likelihood of glazing and ensuring better performance over time. The rotors are also designed to be lightweight, which can help reduce unsprung weight, potentially improving handling characteristics.

When installing these rotors, you'll find they are a direct fit for the specified SL63 models, meaning no modifications are typically required. They are designed to bolt right up to your existing hub assembly. While these rotors offer improved performance, it's always a good idea to ensure your brake fluid is fresh and your brake pads are in good condition to get the most out of your new rotors. If you're planning on frequent track use or spirited driving, these GiroDisc rotors offer a significant upgrade over standard equipment.
