Kinforest are terrible.
i had bald rears on the XR6T and brand new (2000km old) kinforest on the front.
in the wet i could turn the wheel, step hard on the throttle and the rear still had more grip and the car would go straight.
i didn't even bother to wear them out, at 3000km old i left them at a Bob Jane, told them to do what they want with them, except resell them.
change tyres, under steer be gone!
