Quick ratio steering yaris 06-11
I always felt that the steering on the 2008 Yaris could have a touch more feed back and response. So I decided to do some research on finding a quick ratio steering ,my first thought was to find and see if a 2012 Se Yaris would be compatible but soon after realized that the cost of the the rack would be to high and so I kept looking. In the end I ended up with a 2011 scion Xd manual steering rack (ebay $70 usd),It turns out the Yaris 1.8ts uses the same rack as the Xd.
Once i got the xd rack i starteted to measure ,Both steering rack length and height seemed the same and the splines on the in put shaft where the same so it seemed like a direct bolt on but the tie rods seemed the same length but different tie rod end designs. I got the rack on and torqued everything ,I then went for a wheel alignment and aligned the steering wheel .Everything felt great in the steering,quick response steering and more feed back but there is a big down fall in using the xd steering rack ,the rack stroke is considerably shorter then the yaris .What this means is that the turning radius is bigger.(harder to u-turn and park ) DO NOT USE 2008 to 2010 SCION XD RACKS, THE RATION IS MORE THEN THE YARIS ,1:14.7 RATIO. |

Yes ,works good,really like the response and feed back but miss the tight u -turns.I think I found a compromise for the steering though ,a new 2016 yaris base model rack has the same lock to lock but a slight better ratio then the 2008 yaris.(still to expensive to test)
