I only do the cheap indoor karting, but I just found it intriguing because when we do our simracing we are relatively comfortable. I don't know all the g figures and all that, but I always find that the fun out weights any soar back you have the next day. But then again, I'm a former state-champion BMX racer, so maybe I just used to powering through any pain, unlike you fat pussies :P/tootingmyownhorn
