PFF85-620P is suitable for tuned/track cars, but is stiffer and may cause more vibration. For cars with diesel engines, see the PFF85-620R kit. For road-going cars with petrol engines, please consult the PFF85-620 kit. Fitting this silent block to the 1.4 TDI 3-cylinder is not recommended. Note that the extra rigidity may cause vibrations.
Products intended for vehicle modification for competition purposes may render their use prohibited on public roads, insofar as they significantly alter the vehicle's characteristics as specified in the type-approval certificate issued by the relevant authorities (noise level, pollutant emissions, maximum speed, tire dimensions, etc.).
