Floaty feeling at higher speeds common?

[Rigaud]

32f - 28r
205/45R16
1ZZ throttle body and intake, header, 2-1/4" freeflow ss exhaust, lowered and TRD sway bar.
@ 95-100kph I do 5.4 to 5.6L/100km Hard driving.......7.4L/100km

Fuel economy is all about how you drive.
My 2009 2dr hatch swayed....floated on the highway before the sway bar was installed. It holds straight like on rails since.

My '07 suffered from terrible highway wander and float. I installed a rear TRD anti-sway bar which indeed helped with stability at cruise to some degree, but did not eliminate this problem. (Of course, handling in corners was much improved).

I experimented with multiple tyre tread patterns and tyre pressures with and without the anti-sway bar. I discovered that highway wander could be completely eliminated with the correct tyre; tread pattern is all important on the Yaris.

I learned to be very selective choosing the right tyres for my '07 and now my '14. I've always used 205/50/16's with 32 psi front and 29 psi rear. I'm on stock suspension, and I don't use the rear anti-sway bar. I can drive the car at 90MPH with no wander and no float.

How does a rear sway bar effect the front when driving in a straight line?

it does not have any effect unless you have strong cross wind. it's for cornering stability.

not sticky tires, eh? oh, you must have got the pilot sport A/S 3+
you're right. the UTQG is 500 AA A
my mistake...
