Refresh your current racing seat with Kirkey molded foam seat kits. They're designed to add form-fitting, high-density padding to the bottom and lower lumbar of the existing seat to properly support and position a racers body, which is necessary to allow their safety harness to function properly. These molded foam seat insert kits include the liquid foam chemicals, foam sheet tape, mixer attachment, plastic bag, and seat cover fabric material. Please note that this kit is designed to be used with a seat that fits the driver properly "as is". For larger Kirkey race seats, a second kit may be required.
