Made using our range-topping Black 95A durometer polyurethane, these new bushes feature self-lubricating, inner PTFE-lined DU bearings with stainless-steel sleeves, housed in a mild-steel outer shell with supporting washers for compact packaging. This combination of PU and DU bearings delivers smooth articulation and excellent wear, with the compliance of PU and the high performance and precision of a metal bearing, while increasing stiffness over the worn OE rubber bush by 100% at 1mm displacement for true supercar handling.
