Handling changes from rear hub spacers and minor concern.

[YarisSedan]

So after installing my rear hub spacers i can tell there is a handling difference. I supose cause the wider tracking. On corners that if i push the yaris to the limit the tires would squeel slightly. Now the same limit the tires no longer squeel. I have not been able to push it hard enough to the point where they will now on public streets nor would i really want to.

Also during a hilly drive the other day to test things out on some of the sharp corners i notice the rear end shimmys and shakes occasionally. Only way i can explain it is if you have ever driven a rear wheel drive car when the rear end kicks out slightly and then regrips and evens out. Thats kinda how it feels like. But which is strange since our cars are FWD that im experiencing this. I never have before. It could be that since im pushing the car to further limits than before that I have not experience this i am not sure.

Freeway speeds the car seems much more stable.

I guess there pros and cons of having a narrow wheel base. I just have to get used to the car and adapt to it again like after every mod.
