You need either a 3 layer fireproof suit or a 2 layer fireproof suit with protective underwear, a balaclava, racing boots and fireproof socks, fireproof gloves, a helmet, and a HANS device. A typical motor racing starter kit, including suit, boots, socks, underwear, gloves, and balaclava, start from about $1200. Motorbike helmets are accepted and start at about $400, however many competitors opt for a motor racing helmet starting at about $800. Motor racing helmets typically have smaller view cut-outs resulting in a stronger helmet, and have much higher impact resistant visors, but are illegal for ordinary motor cycle use.
