GR Yaris What did you do to your GR Yaris today?

Hi again.

So I found the papers. Im actually a complete rookie when it comes to this topic though so I will just give you my numbers how they are written on here.

Front
Toe left: +0°11'
Toe right: +0°11'

Back
Toe left: +0°10'
Toe right: +0°10'


On the topic of disadvantages of -3° camber though I can say that I have been driving for a year with this setting now and I didn't notice anything out of the ordinary when it comes to tire wear on both the summer and winter tires. I drive around 10.000 km a year though. I guess if you drive more then that then it could become an issue but for me it really hasn't been so far.

And lastly there is this video. I also posted that in the video section but as I watched it I was reminded about our conversation. Because you can really see here how the car rotates to dance throughout this course. It's clearly a modified car with an experienced driver at the helm but it shows that achiviving this balance is possible. It's unfortunate that he is probably not a member of this forum since he would be the perfect person to ask on what you need to do.

Aggressive negative camber doesn’t affect tire wear as much as people think. I daily drove an E46 M3 for 10 years with a front camber range of -3 to -3.5 degrees and never noticed uneven wear due to the camber. In my experience, improper toe alignment is what kills tires faster than any reasonable amount of negative camber would.

exactly this, plus only really need more camber if you're rolling the tyre passed the little triangle marker on tyre edge

Funny that you mention that. I had a gap of one month between installing the camber bolts and getting an alignment. I coincidentally also had to drive a bit more in that time frame and my front winter tires got absolutely shredded by that. Looking at my papers I was driving around in that one month with a toe value of +1°20' on each side.

I knew that my decision could be bad for the tires but I didn't imagine it could be that bad. But hey that's how you learn a lesson I guess.

It does rotate (and sound) beutifully on that video!

Back to the/my normal world now, though, as that car differs to mine in so many ways.

Semi-rookie here and i would say you have quite a bit of toe in all around. So, probably gives you an element of stability, which may counteract antics potentially caused by the aggressive front camber and the overinflated rear tyres.

And perhaps toe in at the front wears the outer of the tyre, while camber must have some negative impact on the inner sides. Perhaps hence no glowing issues with tyre wear but if that was, for example toe out instead of in, I believe you would have uneven tyre wear at that mileage.

My triangle markers are gone so I guess my -3.5F and -2.8R must be needed. 😁

Wow, are there no straight roads / long stretches where you drive? 😊

Is that through camber bolts? If yes, any clearance issues?

Also, what toe have you set to front and rear, as some (@Onehp among them, I believe) say that high camber and high toe settings don't play well together.

You have a point.

Thing is this Sunday I have a driver safety training. You know the kind where you are on wet slippery ground all the time and have to learn to keep your car under control while doing various tasks. Never have done something like that before and Im pretty excited for it. After that I might try some even more advanced stuff.

Only after reaching that point I would feel confident in changing settings on the car further. I don't want to make experiments right now when I potentially don't have to skill to really exploit or handle it. But in a month or two I will have managed to pay off the car loan and with that a good chunk of income is now free to be spent on other things like this for example. So we will see how it goes ;)

Haha, it sees the track quite often so hence the main reason for plenty of camber. It's a combination of camber bolts and adjustable top mounts.
Toe settings are reasonably Conservative. Parallel front and +1.5 deg rear.

Brought the car out of a nearly 7 months "winter" hibernation and also installed hrnshn brake cooling kit and shims.
It's nice to work in wheelhouse's that looks like new, only 16000 km and no driving during winter/spring.

Decided, bit sooner than anticipated, that I'm selling mine......

Going to try various auction routes as the last car trying to sell privately was a nightmare, tyre kickers and no money all of them.

So put it up for private sale in Sweden. Beginning of the end is getting real. Auctions take quite a premium so testing private first, can't add it to the forum as if I want to try auction later they don't allow it to be listed elsewhere...

By the way, Swedish miles are 10km and asking the equivalent of 37k € or 31k £ for my 'updated' car...

I'm now the proud owner of a HKS super turbo muffler exhaust. What a work of art, it looks more like something you would see in a orchestra rather than an exhaust for a car. Sound is important to all music and car lovers and the tune this exhaust will play is music to my ears.

I am dreaming of finding a cheap one in Sweden. Really don't want to spend that much money for a new one as I am rebuilding a blown subaru engine that I bought without even having a car to put it 🤣

Gave mine a wash (bound to rain tomorrow now). Took it for a “mental health” drive after the wife and kid went to bed. Got thumbs up from someone in a very nice looking BMW Z8, then left him for dead around a roundabout.

😎 had no traffic on the way home tonight and took the opportunity to make a detour over a mountain pass…. Better than any therapy….
