If you're looking for the lowest gear, you're looking for an SVX tranny. 3.545 final drive. At 60, it's about 1800-1900rpm. At 80, it's about 2700-2800rpm. Other than that, you can go to a 3.900 which is the final drive of some of the early Legacy 5MT's.
i'm looking for lowest (numerically higher) gear sets. after reading the list of tranny gear ratios, 97-99 legacy outbacks have the lowest 1st-5th gearing out there. not looking for freeway cruising, looking for higher revs in the rally car.
as it is right now, when i am done in 4th and shift to 5th, it's just wont go any faster. so i am hoping going from a .780 5th to a .871 will help me out. that and those trannys have a lower second then what i have right now
