Mr Way do you have a 370Z then or a 350Z as in your avatar?
Just wondered as it wouldn't be the first time someone accidentally posted in the wrong section.
Anyway some food for thought:
Bonnet struts (lifters)
LED bulbs (boot light, number plate lights, sidelights, interior lights, indicators etc)
Stubby (as Durk above mentioned)
Chrome tyre valve caps
Uprated 1.3 bar radiator cap (Mishimoto, Cusco etc)
Performance panel filter
Zed badges/burger badges etc
I could go on.
