The B8 Billet Rear Spring Perch Pair replaces the OEM rubber top perches. Rubber acts as a spring with a mystery spring rate, leading to unwanted oscillations that reduce the ability of your suspension to keep the wheels planted firmly on the pavement. These billet aluminum perches provide the perfect performance reaction surface for your rear springs.
As with all of our products, weight is always a concern. We???ve designed this specifically to keep the weight as low as possible. Weighing in at just 7.6 oz, each, they gain no weight over the OEM parts.
