Same thing for me.. The 05-07 cloth seats were not supporting my back. I have some back problems, so I bougth SVT seats in a junkyard. Lumbars ajustment , reinforced side supports and they are beautiful looking !
I have the red cloth on black leather svt seats set, but if you can find Recaros ... jump on them^^ I don't know for you guys in America but here in Canada, SVT Focuses are very rare.
