Gear Ratios almost in same car/power

[Johnny-R]

I saw this video a long time ago and the difference between this two DC5's is amazing they have the same horsepower (220ps) and the facelift has different gear ratios and it's a lot faster than the prefacelift! It has also a battle between DC2 Spec 98 and facelift DC5 watch it is very good. I love GT channel's videos!

So what is the difference between S40 gearbox(non-lsd) and the S4C + LSD and the S80 + LSD?
