S1 Kits Ultimax and RK rotors

This is the EBC S1 Kit, specifically designed for your 2015-2019 Subaru WRX. It bundles together their Ultimax front brake pads with a set of RK slotted rotors, offering a solid upgrade over your stock braking components. If you're looking to improve your car's stopping power and feel, especially during spirited driving or repeated braking, this kit is a well-built option.

The RK series rotors feature slots that help to sweep away dust and gas that can build up between the pad and rotor surface. This slotting pattern helps maintain consistent friction and reduces the chance of brake fade, meaning you get more reliable stopping power when you need it. Paired with the Ultimax pads, which are known for their good all-around performance and durability, you get a balanced system that works well for daily driving and occasional track use. The rotors are well-made, ensuring they can handle the heat generated during braking.

When installing this kit, remember that it's designed as a direct replacement for your factory brake components. Ensure your brake calipers and mounting hardware are in good condition before installation for the best results.
