Just make sure your paint surface is clean and free of any oils and you're good. Before I sold mine I tested it out on my door several times and it never fell off. :thumbs up But then tying it to something would ease a lot of worry. LolHah yeah. I plan on getting one for the track too. I do like that leash idea though. I might have to steal that idea. I trust the suction mount, but you can never be too safe.
Do you have to get it tuned if you're running that? Since they dont make those SC anymore, how do you know if you bought a good one?
About half way done now. Would keep going but the 37degree outside is slowing me down. Gonna get the JRSC installed tomorrow and running hopefully
