3.69 ring & pinion = stock 6MT

4.08 ring & pinion = 10% shorter than stock

3.9 ring & pinion = 5% shorter than stock

Not only that, but IIRC the 3.9 is an aftermarket and more expensive. IMO 5% isn't enough of a change to justify the work, not to mention it costs more. Just go with the 4.08's and call it a day.
