GR Yaris Alignment, Camber and handling related talks

Stock tyres and suspension?

Any disadvantages?

I ask because this is approximaty the camber setting I am after.

The car has stock dampers and H&R 35mm springs. I've always been totally against new springs on a stock damper. I have never driven a car that got better after replacing the springs. In this case the previous owner installed the springs. In my Honda Elise I had adjusted the dampers and springrates to the respective axle loads....

But the 35mm springs work really well with the stock Yaris shock. I drove my brother's bone stock GR Yaris in a direct comparison on the same day/mountain road/ same winter wheels and Pirelli winter tires. The car feels so much more direct and controlled with the H&R and the aforementioned Geo setting. It is like another car. More confidence inspiring.

The car drives really well. At least I don't have a disadvantage on german roads. The tires will wear a little faster because of course you can't always use the camber. I didn't find any other disadvantages

what camber bolts would you recommend for -3 degree front and -2.5 rear?
Now at -2.2 front and -2 rear but thought of testing more added camber just as corners are nice. Does powerflex ones work or do they loose their adjustment easily?

I'm tempted.

However, I will be installing a caster kit too, simalar to yours. So, thinking of going for a bit more all-rounder setting, eg -2.7 front, -2.3 rear.

It should still effectively provide -3 degrees through dynamic camber due to added caster, ie only when needed.

Could be. Was thinking actually the same.
Though not sure if lets say 0.2 degree makes much difference. but 0.5 degree will already be some. Maybe aim at 2.7-2.9 front and 2.3-2.5 rear.

You've ordered the parts already and you have a history of fitting them promptly; it sounds like I will be getting some expert feedback for the settings I'm after 😊

I can report though it will take some time until getting better tyres and alignment done (likely April). but surely can report.
If I post crash pictures then you know it had too much front camber

So curious how you will like it!
I started w/ -2.5 front, stock -2 rear and that felt like the max reasonable front/rear difference
With my current -2.9/-2.75 setup I have typical camber tire wear (inner worn *noticably* faster than outter, in linear fashion), but would never go back ☺️
Even better than the torque mount insert ☺️

Btw huge benefit of camber change was instantly evident even on soft winter tires

3-4x faster wear sounds quite alot - atm tires wearing more or less evenly.
 
So...
Outter to inner measures are 4.6-4.2-3.7-3.5mm
Actually quite a lot...

All that in 9000km of taking every tight corner like my life depended on it 🤣🤣

Basically unavoidable if running such aggresive camber and not running on track constantly.

Active geo and tyre wear and temp scanners are the future. But takes out the fun a bit eh...

Some more caster and less static neg camber can help.

I rotate tyres with the rear that wear evenly, then it isn't too bad either.

Especially if you have been taking corners like that, camber might not be the most significant factor for this.

Has someone been playing with the front toe, perhaps, @Orion ? 😊

Luckily the rear is more or less idling in this car so As @Onehp said rotating helps alot.
I'm likely going for -2.8F and -2.5R for camber. Maybe it is an improvement to as is.

You have to do more trackdays to even out that wear :LOL:

Yes Sir! And here is the same type of tire, after 4 trackdays of fast but pressure/temp aware driving 🤣🤣

The tires are 225/45 R18 (long story) on BBS wheels so the funny wavy wear may partly come from less tire support
But inner to outter wear is even 😇🤣
