You are not alone in this, I have experienced the same lack of pleasure from my 02 double cab. I have a fix but it is costly, Mastercraft makes seat brackets that can be used to mount many of their race seats as well as some other seats. I estimate the total cost of the swap to be at or above $500.00 depending on the seat or seats you choose. Keep in mind that price is for one seat, not a pair. I am interested to know if a swap for anoter Toyota seat works.
