The Stilo Venti WRC Zero 8860 helmets have an all-new shell design specifically to allow for integration with the groundbreaking Stilo 'WL' wireless communication system. As Stilo 'Zero' helmets, they are designed for ultimate weight-saving-while exceeding the ultra-stringent FIA 8860-2018 requirements for safety. Venti WRC Zero 8860 carbon helmets, as with all the 'Zero' helmets in Stilo's lineup, have been developed for the most discerning competitor. The redesigned carbon fiber shell is constructed using PURO technology which removes the need for a clearcoat to be applied. This further reduces the weight, making it the lightest rally helmet available-which can hugely reduce muscle fatigue. Venti WRC helmets retain the tried and tested Stilo WRC intercom system, but the communications port has been re-designed for use with the WL wireless key (sold separately) which, when fitted, fits perfectly with the contours of the shell shape so it doesn't interfere with FHR posts or straps. The microphone boom shape has been improved to further deflect cabin noise, improving the communication clarity between co-driver and driver. The magnetic dynamic, noise-cancelling microphone is adjustable to allow for optimum spacing from the mouth to reduce external noise. The helmets' intercom system is also compatible with traditional Stilo wired amplifiers, so there's no need to change helmets for vehicles which do not have a wireless amplifier.
