1969 Swinger 340
I was skeptical too, but the car has very little interior in it, and the fenders are glass as well. When I built it I went the light route, so it has no heater, radio, wipers, dodge neon seats, glass rear bumper, no undercoat etc. When I sat in the drivers seat it went up 200 lbs, so I think they are accurate, if not close. I did re zero them because I thought the scales were wrong, and I even tried another battery in one. I was concerned about the weight difference as well on the front, I messed with the bars a little but and got it to change, but I dont know what I'm doing when it comes to corner balancing, so I let it be for now.
