RS Barn Stage 1 camshaft set is a drop in performance upgrade for 968's. Stock camshafts have new sprockets installed and are then reground to maximize performance and driveability. Camshafts are micro- polished and chamfered for best break in and reliability. There aren't any piston clearence issues and performance gains of 20HP to 36HP have been recorded, depending on Header and exhaust combination.
Not recommended for street use. Idle quality is sacrificed for clean performance from 1500 to 6500rpm. Higher flow fuel injectors are required.
