Rear big brake kit compatibility with parking brake system

[CTMP4me]

I'm curious to know which rear BBK setups retain use of factory parking brake or if someone has figured out how to adapt an auxiliary parking caliper.

I have the z34 PFC setup with the V3 rotors (328x30mm), and the rotor hats unfortunately lack the parking brake "drum". It's not an issue at the track and even ok for most parking (always in gear), but it is annoying to not be able to exit the car while it is idling unless its on a very level surface.

most of the mainstream manufactures maintain the rear parking brake.
Stoptech, Brembo, AP Racing etc

Well I was going to got for a full PFC kit but knowing i'll lose the parking brake really turns me off the rear kit. Maybe just get the front kit and match it with the 996 rear i currently have

That's a good direction to go in. PFC is largely discontinuing their older model street/track kits anyway, their z34 rear kit hasn't been available since early 2020. I heard a rumor from a parts distributor that PFC was looking to get out of aftermarket BBK game entirely with the exception of their Porsche GT parts business.

I wouldn't be surprised.... once they started to supply the brake for the 991 cup cars their OEM business exploded.

I guess i'll also look at Alcon... not sure if they allow you to keep the parking brake.

The AP Radical 2 kit fits with parking brake intact. I wanted to go with the AP Pro5000 4 piston calipers for the rear but they have a max rotor size of 330 mm. At that rotor size the diameter of the park brake system shoes do not fit within the rotor Center clearance. The Radi-cal 2 street caliper fits for 355mm x 32 rotors. As you can see in the photos the parking brake "drum" needs to fit within the rotor.
