I am thinking of building a 1in thick box running from the fender well to the fire wall up under the foot well to fill with foam. I already put sound deadening mats on floor and in doors. Also replaced door seals and mod to them. Has anyone tried it. I am retired and always looking to make ride better for wife and kids. I also had a friend make me a boot for my steering wheel. I might go to a smaller tire if this does not work but they are only two weeks old.
