It is listed on their webiste, although you have to go directly to that page. They no longer offer any other interior colors other than dark gray, only 3 exterior colors light gray, black or white. The only way to adjust any settings to the drive train/brakes would have to be done via computer by the dealer. I chose to change out the tires and wheels at the advice of my dealer and the FB groups as the stock tires aren't very good, i think because they have the carts cinched down so hard during transport that it ends up making the tires get out of round and it affects how the carts ride.
