I just got my new lifted Club Car golf cart - I have some questions I need help with. 1. Speed - I was told I can't program this cart with the speed 4 code. This info came from the maker of the program I was looking at. Is this true? I have the little plugin thing under the dash. I also saw a video of someone with a cart just like mine do the speed upgrade. Just trying to make the cart faster - it goes about 15mph now. Please let me know any / all options.. please include a link to any parts or programs 2. Suspension - I know the cart is lifted, but what are the options to make the ride (up front) softer? I have aired down the tires, but it's still really stiff. See pics below. Any help would be appreciated.
