Hello everyone I'm new to this website and I have a couple of questions about rc drift cars. This is probably going to be a long post just a warning. First of all the hex that is on my drift car currently is 7mm. I want to convert it to a 12mm hex to fit standard RC wheels so i can easily change them(and the tires because they seem to be wearing down pretty fast). How do I convert my hex's from 7mm to 12mm? Second I want to find an RC body that is 200mm big but preferably a Nissan Silvia S13 coupe or a Nissan Silvia S14, i can't find any bodies that are 200mm wide and that are also reasonably priced. Any suggestions would be great. That's pretty much it so thanks, any suggestions, questions or advice would be great, I'm new to the whole RC drifting scene so I'm not great at it.
