We'd need to specify interest in the strut housings vs the wheel brg
housings, which seems to be more what you're asking about in your other
post.

Yes, the strut housings are the same(front), the only split being the change
in swaybar mounting position, which is an external tab welded to the housing
anyway, easily adaptable either way.

"Actually, my primary concerns is regarding the offset of the rotor friction
surface relative to the wheel
mounting surface.  If those are the same for either axle diameter, that is
what I want to know.
Most specifically, would G60 brakes, or RS2/Porsche calipers/adapters bolted
onto the G60 mounts, work
with the same rotors in both applications?  Shoot, I remember there being a
difference with the CQ rotor, I
thought.  I'll have to go archive-diving, as well as check out the 20v
pages, for that."

My answer will be no on this one. Based on my recollection playing with the
Coupe hubs for the Lightweight project. The Coupe  brg housings have more
meat on them, creating a more positive offset, pushing the wheels out more
on the Coupe than the sedan. That would indicate that running the same
caliper+carrier would require a different offset rotor for those two
applications. As always, free opinions are worth airtime only.
