Trying to match rotor size needed, to model#

[okieflyr]

My application is a 914 with a Boxster brake conversion front and rear. The rear system was designed to fit w/Boxster rotors, but they will not fit over the 180x25 911 parking brake that I'm trying to keep. The rotor I'm looking for would or could have the following dimensions.

Preffered
290.00mm outer dia
20.00mm thickness
46.00mm offset face to face of surfaces
180x25 e-brake spec


Do able (extraweight penalty)
299.00 mm outer dia
24.00mm thickness
44.00mm offset face to face of surfaces
180x25 e-brake spec

I'm hoping that someone can point me to a series # and year for a rear rotor that fits these dimensions so I don't have to order a warehouse of them to measure.
I have seen some really nice brake summaries (Thanks Bill!) but i've not seen any offset specs to help match things up. This is not an all out racing setup, I'm just looking for an off the shelf solution if possible.

There is an article in Feb 09 Excellence where they used a Carrera rear rotor (24 mm thick) with a 911 e-brake.
They were using 964 calipers which required custom adapters welded to the trailing arms.
From what I read all 911 (up to 89?) e-brakes are the same.

Thanks Trash,

Most of the models share the same brake that I converted too, and I would like to think that the Carrera rotor will have the correct offset that I need.

I'm hoping someone can chime in with the offset measurement to confirm or deny my thinking.

Hopefully this will help 84-89 911 rear

Thank you very much, the height listed is what I'm looking for. Do you have any other rotors listed as well?

Thanks, Kevin
