Hello, I am new to the forum and looking for some advice. I have completely modified an old Thunder Kart Frame to make it more suitable for what I want to use it for. I moved the steering column to the middle, added a live axle, and got smaller wheels. I also might make some more frame supports if I think they are necessary. I plan on making this kart go around 40-45. Does anyone have any experience with something like this? I want to know if it is safe and if I do all the proper modifications if it will work out. I can also post pics. Any advice helps. Thank you!
