This is not scientific, however when I removed the back seats, brackets, seat belts and bolts it was a lot heavier than the rear seat delete. I don't have a scale I can put it all on, but it was a least twice the weight of the rear seat delete. BTW, my car will be a track car. I have another car for driving around town and a truck for hauling stuff. Also, all the weight saved will be lost once I put a roll cage in the car.
Yeah but roll cage is sweet.
