Yeah so I’m a little late on getting to this thread, but I am starting to notice this issue in my 02’.
Question: I will check my tire weights first, but in the case of needing a brake upgrade, is it possible to go with a bigger caliper without a new set of rims and tires? I only have the I.S.A. TRD 16” rims (yes I said 16” rims

) and the clearance is very minimal.
Also what tire pressure do you go with… My TRD sticker on the inside of my driver side door say to fill front tire to 37psi, and 42psi in the rear tire… My tires on the other hand call out a different pressure all together. What pressure should I follow? I’ve driven with both scenarios and get the same outcome with the vibrations?
