Hi again.
 
	To be honest I couldn,t tell you whether they are s tech springs,only that they,re brande Tein and  are green !
 
	By the way ,my previous post said I had Volkswagen wheels....should have checked....they are of course Volks//Rays.Pretty rare I believe as they are a discontinued line now. They also come with a gold spoke setup. Only drawback is that they are AnodisedAluminium so you can’t use the usual alloy cleaner on them.
 
	there,s an excellent YouTube video showing a blue z  with these wheels and a good example of the guys engine dress....great music background too.
 
	type in the YouTube search bar San Marino blue 350 Z Michael  Tegasantos .Let me know your thoughts.
