OK, just to keep everyone in the loop, I fitted new shoes to the Z a couple of weekends ago. I chose 326s, fitted with Federal ST-1s and upped the profile on the rear to 245/35. They seem to ride very nicely, and the slightly higher profile makes the speedo spot on!
I had them refurbed in a Porsche colour - Platinum Satin (code OB5) which although dark, has the slightest hint of bronze to warm up the grey and tie in with the Phoenix Yellow.
