Yes, this is correct. Both Z-21 and Z-20 shields are compatible with the Zamp RZ-48Y Carbon Youth Racing Helmet FIA/Snell CMR - SFI 24.1. The RZ-48Y comes equipped with a Z-21 shield pre-installed, which is thinner and lighter, as required by the CMR standard’s less rigorous impact testing. This keeps the helmet lightweight for youth racers. On the other hand, the Z-20 shield, standard on Snell SA-rated helmets, is thicker and stronger due to higher impact requirements. The Z-20 also offers more versatility, with multiple tinted options and anti-fog variants available, providing additional choices for different racing conditions.
