Upsized my tires, and looking to put less load on the motor... I know that the 4 cy SV with MT came with the 4.363 ratio in their C200K.

I'm at 4.083, so swappign out would only change the ratio by about 7%... so I'd only do it if the ring/pinion were extremely cheap..... Considering it becuase I'm dropping the gas tank to replace the fuel sender... so while I'm back there I might as well yank the rear diff too and swap out gears...
