Having spent considerable time checking & testing cams one thing we have found is that the car manufacturers timing can be out by up to 3 degrees (crank angle) also as the cam chain wears it stretches and retards the cam timing.
To combat this, our GTT adjustable sprocket allows simple, easily accessible adjustment of the timing. Either to the manufacturers spec (using a drop-clock and degree disc) or with rolling-road power runs to optimise power output). Why settle for nearly right when you can have provision for absolutely right!
New Version 2 with wider adjustment range.
Fits: all Gen 1 petrol Models
