Developed on test benches and tested by leading teams, HOT CAMS camshafts are available in three levels.
Stage 1 : increases torque and power with no additional modifications. Ideal for basic tuning.
Stage 2 : better suited to large machines, requires further improvements such as hi-compression pistons and larger carburetor to deliver its potential.
