Has anyone uprated their diffs & gearbox? Any idea what's avaliable\prices etc? I've heard about Grp A diffs, but I've no idea what makes them so different. Straight cut dog gears for an alfa\lancia box.. heard of anyone using them?
right then, its straight cut and or dog box not straight cut dog gears..straight cut will burst your ears it like a reversing noise but in all gears and it stops the side loading pressure of helical gears..a dog box has first gear left and back you then have a straight throw from 2nd to 3rd.
