Adjusting rear camber?? - Toyota Yaris Forums

bribri · 06-23-2009, 12:35 PM

I'm on stock steel 14 inch wheels. Tires are 185/60-14 Bridgstone potenza 960 pole position (all season). I also added a 23mmultra racing sway bar. I figure since the tires feel as if they are rolling before they emit a screaching sound that the tread is not in full contact with the road. Pressure is 38 all around and there is still body roll in the corner (stock springs). I don't want a stiffer ride or to spend more then is necessary to get te car handling great at its limits. Im willing to make allignment adjustments for track and street.

how much camber are you running up front?

2.2 up frontand 2.4 in the rear. The washers are a little thick. I have 1.5mm washersto replace the thicker ones. Your right abouut the back having too much camber. The outside of the tires only see asphalt during hard corners . I have not measured rear toe but with the thick washers the car rotates nicely without feeling unstable. Front toe is close to 0.

I know the design of the rear torsion beam of the Yaris is a bit different to my Echo in that it has some passive toe change geometry or something built in to it, but has anyone checked what happens to the rear toe when the wheels travels through their stroke?

negative camber turns into toe-in apon compression.

That's a bummer, nice and safe from Toyota's point of view I guess.
