GiroDisc Rear Rotors Slotted Pair Subaru STI 2008-2017 | A2-095

Fitment: These high - performance rear brake rotors are designed exclusively for 2008 - 2017 Subaru STI models. Note that before installing these rotors, you'll need to modify the OEM or some OE brake pads. This simple modification involves grinding down the backing plate of the brake pad to match the arc of the pad material. It's necessary to accommodate the hardware of GiroDisc's two - piece discs while keeping the OEM parking brake. Instructions for this modification are included with your purchase. Features: The Girodisc slotted rear brake rotors are direct replacements for factory units, built with performance in mind. They're crafted from U.S. - sourced 6061 - T6 aircraft aluminum and proprietary cast iron. Each rotor has curved directional vanes that work like a centrifugal pump, pushing cooling air through the disc. The floating mount system uses 10 high - strength alloy steel drive pins, secured by grade 12.9 cap screws and hardened washers. This allows for axial and radial float between the hat and disc, and self - centers the rotors between the pads. Anti - noise spring washers let the rotors expand with heat and eliminate rattling. Benefits: Upgrade your brakes with these lightweight, high - performance rotors. They're sold as a pair and have a two - piece design. They work with the OE Brembo Calipers Performance Package. Each rotor weighs around 11 lbs, much lighter than the 18 - lb stock units. The lightweight design reduces rotational and unsprung weight, leading to quicker acceleration and better suspension response. You can also buy replacement rotor rings separately for a cost - effective solution. Please note that the images are for illustration only and may not show the actual product.

Using Your GiroDisc Rear Rotors: Install these rotors on your 2008 - 2017 Subaru STI. Remember, you need to modify your brake pads before installation. Just grind down the backing plate of the brake pads to match the arc of the pad material. The rotors are a direct bolt - on, but with this minor pad modification. Once installed, you'll notice improved braking performance and quicker acceleration due to the reduced weight. Maintenance Tips: Check the rotors regularly for signs of wear. If you hear any strange noises or notice a decrease in braking performance, it might be time to inspect the rotors or replace the pads. You can buy replacement rotor rings separately, which is a cost - effective way to keep your brakes in top shape. Safety First: Always follow the instructions included with the rotors for the pad modification. And make sure all parts are properly tightened during installation. If you're not confident in your mechanical skills, it's best to have a professional install the rotors.
