The Zamp RZ-42Y C4 Youth Graphic Racing Helmet (FIA/Snell CMR) does not include M6 inserts for Head and Neck Restraints, so it is not compatible with spring clips or HANS devices out of the box. While some may modify the helmet by drilling to add inserts, we strongly advise against this, as it could compromise safety and certification. For proper compatibility with FHR/HANS devices, it is best to choose a helmet certified to the SFI 24.1 standard, such as the Zamp RZ-47Y Carbon Helmet, which comes equipped with M6 terminals for secure installation.
