The GT3 wheel option M416) on the C4S and Turbo are as follows:

8" x 18" - ET50 - 996.362.136.02
11" x 18" - ET45 - 996.362.142.02

Also, no spacers are required or used. In addition, the GT3 wheels are lighter than the solid spoke C4S wheels. I would definitely leave them on, if I were you.



My information as shown above is based on Tequipment wheels supplied by Porsche for after-market installation as complete wheel and summer tire sets on C4S and Turbo models. Rear wheels with
a) ET45
and
b) ET63 + 17mm spacer
would correspond to each other (2mm total difference in track).

Looks like they've rationalised stocking for these wheel sets by doing things this way, because ET 63 wheel without spacer fits standard narrow body 996!

Now I really understand Barrett's paranoia about potential for dealers screwing up!
