Oh yeah....Genki's legit.

NO, no.........Those aren't for wheels, unless you're talking about steering wheels for your transmitter.

Keep looking....They're on the site you were at..... They'll look exactly like those, except no caliper. They'll come in two or three different styles and two diameters.

I notice on my Meisters, the large ones take up the entire inside diameter of the wheel. The small ones have a little "daylight" showing through, so it looks like a disc is behind the wheel.

Let me take a look, be right back........
