there are some recent ratio threads mauchie, and you would need to redrill a flywheel to fit a 1.3 g/box (5 bolt/6 bolt crank)

it should be an RS5F41 then, a prefacelift 1.0 k11 diff should fit, but the crownwheel pinion and output shaft are 1 piece tho (so you would probably need the whole gear cluster)

Would the ratios even be different? Would have thought that if anything the 1.2 diff would be taller

Yupp agree with that frank am looking for ither 3.81 or 4.05 any ideas what they come out of the box ave got is a 5speed so a guess thats the 3.81?

So WAY taller then, probably because they were designed with 12" wheels in mind that need to spin faster for the same forward motion than the k11's decadent 13" wheels :)
