That’s Gary Carlton’s chassis line. He was one of the top shifter drivers in the US not that long ago, but now I think he primarily focuses on promoting this chassis line and running his own race team. I’ve linked a thread from a few years ago - it sounds like he worked with TB Kart in developing it, so they are probably very similar and share most major components. Unfortunately I’ve never driven either kart so I wouldn’t be able to help with any driving comparisons, but maybe someone else can.
It looks like one of our local shops will be starting to carry them which is what sparked my interest.
It seems most karts are good these days so always interesting to see a new one come on the market and trying to understand the benefit of the kart vs the other brands.
Pretty sure it TBKart, and pretty sure (thought not certain) that TBKart manufacture their own karts (rather then getting Parolin, Birel, IPK, CRG to make them). They have a pretty big operation if they were only an assembly operation.
CMC have at least one in the shop. I’ve never personally dealt with Gary but I have honestly only heard good things about him. I’m sure on a purely customer service basis he’d be fantastic to deal with.
