taller gears

TheRipler · 08-17-2005, 08:31 AM

The USDM WRX has a 3.545 final drive. What would it take to get these taller gears into an 04 STi? Could you swap gearing without swapping the differentials?

Turns out the diffs are still 3.90s in the WRX. The center diff on the car has a 1.1:1 reduction as opposed to 1:1 on the STi effecting the final drive ratio.
