Like the name suggests, Polybush specialises in polyurethane bushes that will help firm up your suspension and lead to drastically improved handling on the road and track. From full polybush kits to specific anti-roll bar bushes, Polybush knows what it takes to increase performance levels. By upgrading to polyurethane bushes you'll never have to worry about them wearing out as they'll most likely outlive the car itself and won't go mushy like the OEM products.
