SE Steering Ratio
I know the Yaris SE has a faster steering ratio than non-SE models. Does the SE achieve this by offering a different pinion or steering rack?
Just wondering what it'd take to add the faster steering to a non SE. Additionally, what is the ratio on the SE vs non SE?

I just know that I would prefer a 5-door 3rd Gen 5-speed over a 3-door 3rd Gen 5-speed, but I'm SOL on that because I'm not willing to give up the tighter turning circle of a non-SE.

SE:
Steering Ratio - 46.17 Lock to Lock Turns - 2.3 Turning Diameter - Curb to Curb - 36.7 ft LE: Steering Ratio - 49.93 Lock to Lock Turns - 3.0 Turning Diameter - Curb to Curb - 30.8 ft It is achieved with different ratios in the rack. There is a different part number for the two, so you could swap an SE into an non-SE.

EDIT: It does say those ratios even on Toyota's press material, but it cannot be right. My Suzuki Sidekick has a steering ratio of 19.4:1 and I assure you its steering is MUCH slower. Plus, the previous-gen Yaris has a 19.7:1 ratio.

Working it out based on number of turns and degrees of available wheel angle it should be 18.19 for the SE and 21.6 for the rest.

Gotcha. Thanks! That makes more sense.

My math was off a bit, I think I had some part of the equation wrong.
Word from Toyota is 14.3 for the standard cars, 13.2 for the SE.
