need to know where i can get hold of a 25 tooth driven gear for my c4. I'm led to believe that the biggest is 20 teeth. Am running 24" tyres with 3.77 gears and 8 tooth drive gear. How far out would my speedo be if i run a 20 tooth?
The highest gear teeth i know of is 21T.There are some listed in the ford motorsport catalogue that go higher but from memory dont know if they are for c4's.
The highest Im aware of in a 23 tooth. You need to use a ratio adpator or change to a 7 tooth output shaft. Im assuming you have an 8 tooth now.
