Adjustable peak visor HANS post anchors pre-installed Also available with FIA 8860-2018 certification How to Measure Your Head for a Properly-Fitting Racing Helmet The most effective auto racing helmet is one that fits your head properly. Your helmet should fit snug all around your head without putting undue pressure on any point. It should not move around when you shake your head side-to-side or up-and-down. (If it does, imagine what it will do in a crash.) To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one. This helmet will ship with signature required for delivery. 1 Weight may vary based on installed accessories.

Ford Mustang FR500S Front Rotors The Girodisc 2-piece front rotor upgrade transforms the braking performance of your Ford Mustang FR500S. Designed as a direct-fit replacement for the factory rotors, these lightweight floating rotors bolt right up to your OEM calipers without modification. The result is reduced unsprung mass, sharper pedal feel, and vastly improved heat control—whether you're hammering laps or driving spiritedly on the street. Each Girodisc rotor combines a 6061-T6 aluminum hat with a proprietary cast-iron ring, both engineered and machined in the USA. The internal curved vane design acts like a miniature air pump, forcing cooling air through the disc to stabilize temperatures and prevent fade during repeated heavy braking.
