Brembo 97-04 986 Boxster Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Black HA

This Brembo rear big brake kit includes everything you need to significantly upgrade the stopping power on your 1997-2004 Porsche Boxster 986. You'll receive a pair of four-piston aluminum calipers, a pair of two-piece 345x28mm slotted rotors, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear braking components with a more robust system, offering improved performance for spirited driving and track use.

The calipers are cast from aluminum for a good balance of strength and light weight, and they feature a four-piston design. This means more clamping force can be applied to the rotors compared to a typical two-piston setup. The rotors themselves are a two-piece design, which helps manage heat more effectively and can reduce the risk of warping under heavy use. The slots on the rotor surface are there to help clear out brake dust and gases, which keeps the pad surface cleaner and allows for more consistent braking performance, especially during repeated hard stops. This kit comes with black calipers, giving your Boxster a subtle yet aggressive look behind the wheels.

When installing a big brake kit like this, it's a good idea to also consider upgrading your brake fluid to a higher temperature rating to take full advantage of the new hardware. You'll also want to ensure your brake lines are in good condition, or consider upgrading to stainless steel braided lines for a firmer pedal feel. Refer to the manufacturer's installation instructions for specific details on mounting and bleeding the system.
