The "accessories" shown in red above must be replaced without exception, according to the CATCAMS reference (click on the images):

Unlike many of its competitors, which machine their cams from cast steel, CATCAMS machines its camshafts from billet, which makes them far more durable. In most cases CATCAMS camshafts are hollow in order to reduce their weight.

CATCAMS has been recognised worldwide for years for its expertise in camshafts and in the parts that go with them (valve springs, mechanical cam followers, vernier cam pulleys and so on), thanks to its know-how and its detailed study of engines and applications. Every camshaft profile has indeed been developed to suit the specific features of each engine, and also the intended use: road, sport, rally, run or circuit.

Two parameters matter when choosing a camshaft profile: valve lift and the angle, that is the opening duration. A longer opening duration increases power and torque, while more lift optimises power at high engine speeds.
