Another thing I've improved on the cheap is the seat. As delivered, seat fitment was pretty sloppy, with quite a bit of side-to-side and up-and-down movement. I also wasn't pleased with the forward angle of the front portion, which restricts your seating options. I considered sending the seat off for customization, but that would be pricey and require more down time, which I can't stomach. Instead, I tried shimming the seat with 3/4-inch round, 1/16-inch thick adhesive-backed polyurethane pads ( mcmaster.com ; $5.43 for a sheet of 25). This tactic worked wonderfully. I added one shim each to the rear bumpers, two each to the middle bumpers, and stacked four shims on each side of the bracket that supports the front of the seat. I've taken the slop out of the seat's fitment plus raised the front of the seat about 1/4-inch, which reduces the forward slant slightly. All this for about $6 and 10 minutes of my time. Now that's what I call a major budget success.
