Im wanting to order some rota wheels from wheeldude but have a few questions before buying. I had a guy named Joseph respond to my email but have yet to hear back from him. I want to know what the price would be to custom order the Rota rt5r wheels in 5x108 18x9.5 with a +35 or +38 offset. Also what colors are available in this wheel? Im wanting either hyper black or hyper blue. And is the rt5r wheels more concave than the rt5 wheels? Also i have rota grids now with carbon fiber center caps, can i still use these center caps with my new wheels? Sorry for all the questions, just want to make sure before buying them. Thank ya for the help.
