Developed in conjunction with the WRC engine valves, Roger Clark Motorsport have developed their own range of high quality uprated valve springs. These springs offer an increased spring rate over the standard genuine spring, helping to eliminate valve bounce at high engine revs. These springs have an unfitted length of 54mm, a coil diameter of 3.8mm and weigh in at approx 48gm each.
