Freeway tire grooves swaying car

[spets]

Yup, the 25mm are long enough to hide the original stud entirely within the spacer. Shorter spacers will cause the studs to stick out and interfere with the wheel.

The OEM front track is 56.5" and rear track is 52.2", a difference of 4.3". These spacers add 1" to each side so you're basically getting halfway there. These still make a dramatic difference in how the car follows highway grooves.

Thanks, I will order a kit of spacers.

That will also make a difference in snow. It is very bad that the rear wheel does not follow the front wheel snow trace.

The link you post is the correct kit for insight right? Same as civic?

Yeah, you want a 4x100 bolt pattern, 56.1mm bore, 25mm spacer.

Thanks a lot spets. Hope that my winter tires will not rub against the panels.

And that extra 25mm added does not make the tire interfere with the spats/skirt?

Nope. They come close, but as long as you run OEM or close to OEM tire sizes you should be fine.

There are a few pictures from somebody else here:
25mm rear wheel spacers installed - they fit

They are narrower to allow the body to taper more with good clearance to aero shields for the max in service size of that tyre spec. Having a known tyre size and being enthusiast we can manage those issues. Hell it might even have clearance for snow chains on the tyre envelopes.

If anything they would be better as the leading front wheel cleans the airflow for the rear and also wet roads water is moved for more of the rear tyres.

Ride the ridges (stay out of the ruts). A hypermiling technique that helps with the 'swaying', also protects against hydroplaning during heavy rain when the ruts fill up, particularly with beefed up tire air pressures.
