Are rear caliper adapters required for Boxster brake conversion?
I am going to convert my 911 SC brakes to NON-S Boxster brakes, using Carrera 24 mm rotors up front and SC 20 mm rotors in the rear. (I have seen the numerous threads about the propriety of this choice so no need to re-hash it here).
My question is: I see that many vendors sell the adapters for the front Boxster calipers to the 911 spindle, and I know that I will need those. What I do not see though, is whether adapters are required for the REAR non-S Boxster calipers to fit the SC rotor properly. If so, does anyone have any experience with these adapters and have any recommendations as to which ones work well. Thanks in advance for your help. |

Yes, I saw their front adapters and their rear adapters for using "S" brakes, or 996 brakes, but did not see an offering for non-S rear brakes. I will need to call them.

Yes, adapters are required for both front and rear. The rear adapter moves the caliper more towards the top of the rotor.
Not familiar with a kit for the S versions. To my knowledge the kits all required the early non S calipers.

I spoke with Stomski and they confirmed they do not make an adapter for the rear caliper.
Rodsrsr, are you aware of anyone who does make the adapter for the rear caliper? |

Reach out to A914guy, pretty sure he has what you need.
https://forums.pelicanparts.com/porsche-911-used-parts-sale-wanted/964580-boxster-brake-caliper-adapters-911-a.html I bought a set of fronts from him and they have been problem free for years.
