Why this upgrade works

In Road Series specification, PFF5-1901 is engineered to be substantially stiffer than the original rubber bush to better control deflection under acceleration, cornering and braking. By limiting unwanted arm movement, alignment stays closer to target settings, which yields a more direct steering feel and a calmer front end at speed.
