I just completed my spoiler. Originally, I installed a 130x80x16 motorcycle tire in the rear! It's 5.5'' wide! Turns it in to a cool rear bike tire! But then I had to figure out: the engine and what would work because there was no room for another chain or belt. I called around and nobody had a wide friction drive kit! so me and some welding buddys & a machine shop dude got together and made one! Turned out awesome! Rides good so far, as I have'nt really put it to the test![knock on wood]. I also put a 24x3 on the front and it rides pretty good! Heres a couple of pics[if they came out?]
Looks Awesome
