Getting a seat that fits you and getting you fitted in the kart is huge. If you have to hold yourself in any position your driving will suffer and you will tire quickly. I wear a strap around my torso and hook it to my helmet, it really helps my neck go the distance. Everything has to fit. Helmet, neck support, seat, steering wheel, all of it! Get comfortable and just drive. Once you find the right seat, dont ever let it go. Seems no two are the same. I really like the ones that Wayne Felch designed and built. There are guys now building copies, if you can find one try it. You wont go back to the typical laydown seat again.
