Although not highly visible or obvious...each of these counts as a "modification" per the rules and pushes the car out of Stock class. Within "Stock" class, you're permitted up to 3 mods to stay in the class...even though you're still docked the up to 3 mods allowed. This whole thread is leading me to believe that your Z would have been better suited for either Nissan or Ultra modified class. I'd be happy to help you determine proper class for your Z...it's a simple question of counting visible modifications. This is the same approach of judging that many concourse shows follow...the ZCCA rules actually morphed out of other long-standing concourse judging criteria (think of any big concourse event...i.e. Pebble Beach, Huntington Beach, Amelia or the more local Glenmoor Gathering).
