What is widest 18" tire/wheel combo that will fit '92 964 C2?

General concensus is 8" front 9.5" rear and again that depends on which tire you run and also the alignment i.e. negative camber.

rear ...
10" is any easy fit with the right offset.
11" is possible according to a few reports here.

I was looking through older threads the other day and user "kgorman" states he is running this setup.

F: 245/40R18 ET56 8.5" Rim
R: 275/35R18 ET65 20mm spacer 10" Rim

I PM'd him for pics but haven't heard back.
