Hello, I run a 2019 Compkart 4R chassis in the Briggs and Straton lo206 Senior class. I don’t see a lot of things on here for compkart. I just wanted to help people with my experience and people I race against also with a compkart chassis. At my track, the top 3 in lo206 senior are usually compkarts. I will add any details I remember an answer all questions I can.
Just for reference, I’m a skinnier, 160lbs, 6ft 2inch male.
