Congrats on the order. I am considering powdercoating my ZCP wheels also, think I may contact IND about it. I would recommend you do the same to start piling up the mods. I suggest doing some minor appearance stuff first then moving on the exhaust/mechanical stuff. One you start modding, i is hard to stop though.
Good luck and enjoy!
