About this part

Product Details

EBC is known for making well-built brake components, and these Ultimax slotted rotors are a solid option for your 2004-2008 Porsche Boxster. If you're looking to improve your braking performance beyond stock, especially under harder use, these rotors are designed to help. They feature a unique slot pattern that's engineered to keep things quiet, unlike some other slotted rotors that can create extra air noise.

The progressively angled slots do more than just look good; they actively help your brakes perform better. By pulling in cooler air, they help reduce brake temperatures, which is key for consistent stopping power. These slots also work to sweep away brake dust and road debris, ensuring your brake pads maintain maximum contact and grip. This not only helps your brakes work more effectively but can also extend the life of your brake pads by keeping them cleaner.

This set is for the front of your Boxster and is designed to fit with cast iron rotors. They are vented rotors, meaning they have internal vanes to help dissipate heat, and they come with 5 bolt holes. The rotors measure 298mm in diameter, 67mm in height, and 24mm thick, with a 98.1mm center hole diameter. They are intended for use with FMSI pad number D737.
