GR Yaris Camber bolts

[Phil1291]

Hey, reviving an old topic, but I think all of you are still active in the forum.

My plan is to get the "two dots" bolts for the top bolts for track usage and go back to stock bolts for the street. How is my toe being affected by changing only the top bolts, has anyone measured it before and after?
I don't want to run more camber on the street mainly because of the winter time, but don't want to keep getting an alignment before and after the track either.

I know that aftermarket camber bolts change the toe completely because the washer is only positioned in one side of the strut.

You need to do an alignment whenever you change the bolts.
Everything else is just guesswork.

Listen to this man.

I have the Toyota bolts installed too but I got an alignment one month after installing them which was a huge mistake. That one month of driving was already enough to delete my two front winter tires because the settings were so out of wack. And those weren't some already used up tires. Those were Bridgestone Blizzaks which had a lot of life left in them.
Just switching the bolts is unfortunately not how it works.

As reported elsewhere I got the following results with one bolt each side (without messing about with two OE bolts each side which are difficult to adjust if following the above table):

1pc ONE dot bolt (90105-17013) upper hole, full articulation (lifting wheel hub with both bolts loose before tightening) = 2,3 deg neg camber both sides

1pc TWO dot bolt (90105-17014) upper hole, full articulation (lifting wheel hub with both bolts loose before tightening) = 3 deg neg camber both sides

I got surprising even result left and right, YMMV. 10min job each side, parts cost peanuts (bolts + new nuts too).

If you want to set a very specific camber angle, it is much easier to finetune the angle with an aftermarket lobed bolt. However no longer OEM parts and perhaps might suddenly snap if overloaded (e.g. overtightened + big pothole).

PS: I settled for 2,3 deg neg camber, with 3 deg neg camber and winter tyres car became much too lively in the rear at high speed and I want a setting that works year round...

The 90105-17013 bolt has a diameter of 15.9mm?
