ARAI GP-5W SA2010 Auto Racing Helmet - Wider Eyeport and Vents for Closed Cockpit race cars. Finally, a helmet designed specifically for use inside a closed cockpit race car. A very similar design and specification as the previous models, but with some ventilation changes and a 90mm eyeport (compared to previous 72mm). All of this, and the same formula that sets Arai apart through lightweight design, superbly strong shells and a perfect fit interior, make this the new helmet the one to have. Rated: Snell SA-2010
