Trust me, the 2gr delivers all the wheel spin you want even with 3.625 gears. 1st and 2nd gear still spin on demand and 3rd will spin if you kick the clutch.

at 870 rev/mile (stock MK2 tire size):

4.285 final gives 3200RPM at 70mph
3.939 final gives 2900RPM at 70mph
3.625 final gives 2700RPM at 70mph
