Hello,

I'm hoping to find a source and info on a better final drive for my 2005 Scion xA. It's a 5-speed manual with a 1.5L VVti engine, and the final drive is 4.31:1, and so even though both 4th and 5th gears are "overdrive" ratios, it still is only going 40mph in 5th gear at 2000RPM. At 55mph, it is turning at ~2500RPM and I would love to drop the RPM's ~20% down to 2000RPM.

This is the one imperfection with my local Toyota dealer (Acton Toyota, now in Littleton, MA) -- they do not have the info (inclination?) to find out what Yaris\Echo\Spectrum\xA\xB part(s) would be a bolt-in fix for me...can anybody here help me, please? Especially if you have done this on one of these Toyota vehicles.
