I just don't understand why they didn't just offer the thing either with metric or US nuts. Instead of charging extra for the metric ones. I know Losi and Associated are popular, but their the only two of about 30 types of TC's out there that use US nuts. Anyway, maybe I'll get lucky and get one with the metric nuts without having to pay extra for them. If not, I'll pick them up later.
STLNLST: I really don't get the point of the front caster setting either. I have run cars with standard suspension and pivot balls. One thing was alway constant though, you knew how much caster you had. Even if it was adjustable, you still knew excatly how much. I guess if you lose your cars manual and don't know how much you get from putting this clip here, or that clip there, I guess it can be useful.
Seems like Integy has put together a nice product here, so it looks like a safe buy.
Thanks again for all the input.
