Sorry, I am in the same sinking Impact or 235mm boat that you are in! We both need tires as I only have 1 new set of rear tires NIB and my front belt is missing teeth. I remember that someone once had a wide belt conversion to replace the wimpy front belt, but I have not found anyone that has one to copy or even remembers who made it? I do have a few suspension parts but only enough if I ever want to run for fun. I do have a light wieght chassis that I could part with?
