Product Details

***Please see ES3200692 to build your own custom kit with these adapters!***

This caliper adapter kit allows you to mount the rear Porsche 996 / Boxter S Brembo calipers to the rear of MK4 chassis vehicles. A factory rear 337 / 20AE / GLI 1.8T / R32 / TT caliper is used in conjunction with the 4-piston caliper in order to provide parking brake duties. This setup is intended to be used with the 280x22mm rotors found on MK4 2.0L/TDI models.  

The Porsche calipers are connected to the hydraulic system of the vehicle for increased braking force. Since they have no hand brake function, the factory rear 337 / 20AE / GLI 1.8T / R32 / TT caliper is used for the hand brake function only. The hydraulic connection on the hand brake caliper is closed, so it requires a blanking plug.
