The 997 was sold in 997.1 and 997.2 versions with different brake hardware, and S and Turbo models differ again. Confirm fitment by year, trim, and brake package before ordering.

Why slotted rotors

The slots machined into the face of the disc give gas and pad debris somewhere to go instead of building up between the pad and the rotor. That keeps the pad face clean as it wears, so bite stays consistent through repeated hard stops rather than tailing off as the brakes heat up. Slotted discs are a common upgrade on cars that see spirited road driving or occasional track days, and they pair with the pad compound you already prefer.

Installation

These discs are built as a replacement for the factory units on the listed application, so the job is a standard rotor change: pull the caliper and carrier, swap the disc, and bed the brakes in before hard use. Inspect pads, hardware and hoses while the corner is apart and replace anything worn at the same time.
