I have added the suspension rear axle and "deluxe" seat to mine, (from Corey Jensen at WindPower Sports, Las Vegas,
http://www.windpowersports.com), along with some aluminum ultralight aircraft wheels from Dan Rubesh, the Windwizard (
http://www.windwizard.com).
However, the BEST modification would be to either add a mobile welding rig, or sell it and get a Libra buggy, IMHO.
I have had to have every weight-bearing or stress-loaded weld on my PL and the recently-purchased axle re-welded, at 30-50 bucks per weld. These
China-built buggies have too-thin tubing in the frames, and VERY bad welds, everywhere. Sorry to the die-hard Peter Lynn fans, but poor quality is
poor quality, and these things ain't cheap.
