Yes, those will increase the vibrations transmitted to the body. Take them out and see what you get. The best mounts are the vibratechnics that Colin sells.
ok - alignment is done - got the call from the shop. $150... had to drop the coilovers to set the front camber, and the "tie rods were completely seized" on to the next project - parts are already ordered - a complete brake overhaul for my Tundra... so I can sell it with a good conscience ;-)
