What version of the Bmax4 do you have? basic kit? Worlds 2009 kit? Team factory kit? Bmax4II kit? etc...???
It would help to know as each kit has a different group of upgraded components. We can,t tell you buy this, it is really worth it, if we don,t even know if you have it. maybe a few pics would help us out.
Great car by the way...
