My brother heard today from a Porsche onwned dealer today that a C4SS is possible for 2006.I stress SS and not S. Probable 15mm wide and extra power with 400bhp. No C4 available but C4S being base 4wd model but unsure wehter it will be 15mm wider. This like i said was from the only porsche owned dealer in uk. C2S can be specced and delivered in late June early July due to extra allocation because they are owned by porsche uk.
