At the moment i'm running 46t and 51t spur gears and the clutch bell is 16t and 21t. When i got it the spur gears were 46t and 52t but the clutch bell was still the 16t and 21t which means the split was out by one so i changed the 52t spur to the 51t so now the split is the same, is this correct? I haven't driven it yet on this combination but i am a little worried as my other G4 runs a 47t and 51t combination which means it has a split of four but my new car has a split of five, is this going to affect the performance in any way??? Hope you could follow my ramble as it can be quite confusing Does anybody know where i can get information on how to gear your car properly?
