Best part is, the kart was $400, cage was $150 with body. Not bad to have a roller with some spares for $550. I've done extensive work to it since, but there was no way I'd have gotten a QRC or SKE roller at that price, even if I knew what they were at that time. Now that I DO know what they are, I may have a custom frame produced with a couple of their features tweaked a bit. We'll see. For now, it's time to get this one on-track and see how she does. As a cool side note, the seat is Ward Burton's old seat that I purchased from a team engineer. He was a small guy!! Glad I am too....
