pulleys = good ( i only installed crank pulley )

idle = smoother
heel/toe = easier
throttle = more responsive

btw. i killed a wrx sti today. I am not saying i can kill any sti - it was a drivers race and i won - no bs. at the top of second he was behind my front qtr panel, he bailed about a second after we both shifted into third - to avoid getting WALKED. see my sig for my mods.
