I'm loving my new 3p, except it's too low. I was visiting a park and heard a sickening thump as I went over a speed bump at 2 mph or so. Seems like the extra 10-15 mm would really help clearing curbs when parking, handling speed bumps, and handling steep up/down for driveways and the like. Anyone know exactly what parts differ between the model 3P and the model 3 AWD that accounts for the height difference? I'm aware of the MPP 1.75" suspension lift kit, but I wasn't looking for that much lift. I think even 10-15 mm would handle most normal road conditions.
