im currently in the process of designing a new r/c drift tire. I dont know whether it will have rings or not, since im still designing it, but it will have this one cool feature which no other r/c drift tire ive encountered has; it will smoke. meaning that it will have a much more realistic drift look, which, of course, is good...im sure you know what thatll mean. prices tentatively are: carbon fiber rims, $30-35/pair, plastic $20-25. would you buy this kit? please let me know so i can plan whether to make this or not. if anybody knows how to put this into a poll, please let me know and do so.
