Using the Tillett T11 Kart Racing Seat is easy. First, choose the right size according to the provided measurements. Make sure to install it properly in your kart following the standard installation procedures. When you're in the seat, adjust your position to sit as low as possible to take advantage of the lower center of gravity. As for maintenance, keep the seat clean by wiping it with a soft, dry cloth regularly. Avoid using harsh chemicals that could damage the fiberglass. Also, since this seat is a bit larger than other Tillett seats, double - check the fit in your kart before use. And remember, due to its size, it doesn't come with free shipping.
