Cam gears are a waste of time and money on the Zetec. The EEC takes the Cam TDC from a spur on the shaft itself and the crankshaft sensor provides engine information. The EEC changes the timing.
If you offset the TDC and crankshaft then the computer will correct
They do look good though. Save the money and get a good programmable chip instead which will let you really change the timing at variable amounts rather than a single fixed amount
