If your buying new wheels anyway, why do a spacer? I had spacers on stock jeep wheels, I didn't have any real problems, but put on wheels with proper backspacing as soon as funds allowed. Just seemed ify with a set of lug nuts you cant easily check hidden behind the wheel.
Denali's are available with the z71 pkg, you can get them with the z60 or z71 suspension. Also to add to the list here my ccsb AT 6.2 has aluminum, never gave it much thought but after reading all this I went and looked.
Im not sure were your at but if its cold you might want to take a heat gun and go along the edges to help the rubber settle down. I did mine and bed has been virtually dry inside since install. Take care not to melt it lol. I just did one nice smooth pass.
I have the vp, was in the same boat, couldn't decide between the vp or g2. It advertised the vp as flat with no hinges showing, well from 10ft off it is. If you walk up to it you can make them out under the vinyl. With that being said, I love this cover, easy install, looks great, has to be one of the lowest profile covers available. It sits damn near flat with the bed rails.no water whatsoever on my bed rug either. Definitely recommend it.
What are the main differences between the 2? I looked up and found the vette and it shows 450hp vs our 420, is it all tuning? Are there any simple changes to make it match the vette? I know you can do anything with aftermarket parts and tunes, but I think itd be cool to do it with factory parts. I intend to put the vette vaule covers on just as a convo piece (if possible, yet another ? Lol)
