Is it worth the money to switch from direct spindle mount to metric mount?

Are MXC wheels worth the money?

I have read conflicting opinions on this. Have you guys tried them and seen an improvement to justify the cost? We run lo206 with evinco blues. I have only seen a couple of karts with them. Most guys run Douglas mags.

I’m still skeptical on claims that wheels have different “stiffnesses” in any meaningful, measurable way.

I will say that different materials (and wheel volumes) can affect how the tire pressures develop during a race though.
