No, but I have already balanced the car closer to 50/50 than factory, and I will be putting a roll cage in the back which will make it even closer to 50/50, or maybe a little more so I figure at worst it will still be better than factory weight distribution and probably a little lighter. Just was not sure if the weight savings was worth it so I figured I would ask about any experiences. Its a 2+2 and its not a DD, but not a strict track car either.
