Hi all,

Does anyone know categorically what the rear diff ratios in the AUDM post-FL 4Gen GT Spec.B cars are, for both the R160 in the 5EAT cars and the R180 in the STI 6MT cars?

There's a lot of conflicting information out there...

Cheers!

3.08 rear diff ratio for post facelift 5eat

3.54 rear diff ratio for r180 6mt

Thanks Mick!

And I believe near-on impossible to get 3.08 ratio sets for the R180...

Definitely impossible

Would need a frankestein approach from a r200 or 240, however pinion wheel and crown may be physically different sizes
