What you're saying does make sense, if the assumption was correct. But it's not. Cars are designed to carry 4 passengers full time.Jazzie604 said:hey igs, i dont want to sound like too much of a smart ass, but go throw an extra 800 pounds in your car and drive it for 6 months and then tell me how wonderful the suspension is. I believe you when you say they are built to be capable of carrying that much load and adjusting to the TEMPORARY changes in geometry, but a constant change in geometry probably wasnt in mind when they built the car. As always I could just be blowing smoke up my own ass, but this makes sense to me.
