EBC GD Sport slotted rear rotors for 1997–1999 Porsche Boxster 2.5L are made to OE grey cast iron specifications and, where possible, are British made in EBC's UK foundry. The 3GD rear rotor set is vented at 291mm diameter and 19.9mm thick; wide slots remove dirt and debris, reduce brake fade under load and help brakes run cooler. Verify rear rotor dimensions and fitment for your Boxster.
