I know there's post on how to lower the weight of your car in GT5, but how do you increase the weight of your car? What's the limit and does it matter which chassis you use? Do you have to use either the GT5 Garage Editor v1.6 or HxD? Whenever I try to change the weight of my car using hex codes in GT5 Garage Editor v1.6 the save file doesn't load. Other then that I don't know if I'm putting the 8 digit hex code in wrong or not.
