I havent experienced anything abnormal or uncomfortable.
Steering feels straight, tight and right; and I havent noticed any changes in how the car handles whatsoever.
It's been about 6-800 miles since this fix, including a 420mile mountain trip where the wagon towed a trailer and cargo perfectly. Not just for the cooling system and for the pushbutton 5speed tranny alone, but that was the ultimate test for the scooter wheels too.
I havent noticed any weirdness about driveability and all was fine, even at speeds of 75MPH with the trailer on. If I took my hands off the steering wheel, the rig would still cruise vibration-free and completely straight.
I think I would never go back to saggy back...
IDK how if it affected caster.
Rotating the tires is a good idea anyways so I'll keep that on the list for the future.
After the wheels added, I had to adjust driver seat, all 3 mirrors and I see less of the length of the hood and more of the road
It doesnt feel any stiffer but I think it may have stiffened it up by 5%. Not sure. I am receiving no feedback at all that something has changed.
