I have a 08 Carbon Silver Z and was thinking about buying a prepainted bumper, but wanted to know if it is the same color as the 03-06 Silverstone Z.

 

no its not the same color. Its a different shade but very similar

 

if you see a CS and a SS parked right next to each other you'll see the difference, other than that, i have noticed that only Z enthusiast (mostly) see the difference between if one or the other were randomly driving by. most people think the "silver" is just one silver.

very much alike, tho

 

Carbon silver seems to be darker, in which I like over my SS.
