Welcome... I haven't seen any with stripes yet.
The eBay ones look pretty good too. Depending on how you're accenting it (i.e. color), you could very well do the silver or red also. Personally putting either the flat matte or red on my 2011 Black R/T.$50 on eBay. Various colors, with the white the obvious choice would be black. They have super glossy, semi gloss & flat matte. Good luck. Post pics.
Any good vinyl shop should be able to hook you up. www.revolution-motorsports.com is a vendor on some of the other z forums. They should be able to help.I'm actually wanting to do an offset striping in red like they have for the 2011 Mopar Charger. Anyone know where I could find those stripes?
