My son is getting into Mini Sprint Racing and he is just about to start growing like a weed. Searching for a good used Full Containment Seat that will fit his 14.5" hip-to-hip width when sitting in a chair. We currently have a 16" seat and there is too much slop in the seat for his thin frame (5'2, 100 lbs). Thinking someone might have a good youth or small adult full containment seat they are looking to sell.

Thanks, Mike
