I didn't put them on a scale but they felt similiar in weight to the stock 17" Bullits. When I purchased them I was worried about that too but when I was installing the springs I took them off and was suprised they were not heavy. This is just my opinion as I do not have any data (weights, dyno, 1/4 mile runs) to back this up. I feel no difference in the ride and acceleration with the 20"s vs the 17"s. If you race your car it is probably better to choose a light wheel with a smaller diameter. But if you are like me and use your car as a daily driver and the occasional stop light to stop light run you will love the wheels. What color were you considering, black, chrome, or anthracite?
