with all high powerd rst,s mate everything is put under that bit more strain i had a 250 bhp s2 and it went thru steering racks engine and gearbox mounts and wheelbearings go for fiesta deisel mounts just as good as the jazzy colourd uprated ones and try a new rack as torque steer batters them, get it to a garage up on the ramps and give a full once over i always do this with new cars saves ya comming across things later on when you want it reliable hope that helps abit
