What is the benefit of the slots on these rotors?

The slots machined into the rotor surface help to sweep away brake dust and gases that can accumulate between the pad and rotor. This action helps maintain consistent pad-to-rotor contact, which can improve braking performance and reduce the likelihood of brake fade, especially during repeated hard stops.

Do these rotors come with new hardware or pads?

This product includes the GiroDisc slotted rear rotors only. Brake pads, hardware, and any other necessary installation components are sold separately. You will need to ensure you have compatible brake pads and trim them as required for installation.

What does it mean that the rear pads need to be trimmed?

Trimming the rear brake pads is necessary to ensure they seat correctly against the rotor surface. This is often required when upgrading to different rotor designs or sizes to achieve full pad contact and optimal braking performance. Always refer to the manufacturer's instructions for the correct trimming procedure.

Product Details

These GiroDisc slotted rear rotors are made from a high-carbon iron alloy, a material chosen for its strength and ability to handle the heat generated during hard braking. The slots machined into the rotor surface are a key feature, helping to sweep away dust and gas that can build up between the pad and rotor. This action helps maintain consistent contact and improves braking performance, especially under demanding conditions where heat can cause brake fade.

Designed specifically for the 2004-2007 Subaru Impreza WRX STI, these rotors are a direct replacement for your factory units, though it's important to note they require your rear brake pads to be trimmed to fit properly. This design choice is common when upgrading to larger or differently shaped rotors, ensuring optimal pad engagement across the rotor face. The high-carbon iron construction not only contributes to braking power but also offers good durability, resisting warping and cracking even with repeated aggressive use. When you're pushing your STI hard, having rotors that can keep up is crucial for both performance and safety.

Installing these rotors is a straightforward process for anyone familiar with brake work, as they are designed to mount directly onto the existing hubs. While they are a direct fit, remember the requirement for trimmed rear pads. This upgrade is a solid choice for WRX STI owners looking to enhance their braking system's responsiveness and heat management capabilities, providing more confidence during spirited driving or track use.
