I had it installed on my SRT a month or so after I got it. Right after I got my first stone chip it was apparent to me that it is quite literally the ONLY way to effectively combat the problem. Quite pricey, its going to run you 500-1000 for the material and install. BUT, I will say it was one of the best investments I have made.
couple suggestions:
-Professional Install is a MUST.
-Make sure you go with someone who has a CNC material cutting machine and the program for the Viper. you DO NOT want someone to cut that material on your paint- a lot of places do! Trust me, come time to ever remove it, they werent as slick as they thought they were with regaurds to not cutting all the way through the material...they are good, but not that good.
-Lighter color cars make it VERY difficult to see the seams during the day, and are only visable with shadows. Dark colors are the opposite, easier to see during the day, more difficult in Dim lighting.
