I have been trying to make sense of what final drive options are available and struggling! I have a C52 box with an aftermarket LSD fitted to my car, but also have a C56 box with an aftermarket LSD out of my glanza. I could do with dropping the gearing slightly,and was thinking about the idea of changing the final drive to drop it. Does anyone know what is available to drop it. I know TRD do one that is very expensive! Is there any other C series toyota boxes with a different final drive? Cheers
