Default Can wheel spacers mess with alignment?

Had 20 mm bolt on spacers put on before, i honestly dont remember when car was new if this issue was present, but i do notice alignment is slightly off, when wheel is straight, car will go to the right slightly.

Is it possible for bolt on spacers to cause this issue? About to take car in for first oil change and wanted to see if i can gain leverage in having the dealer do a free alignment.

you have a slightly lower wheel rate so i suppose this could happen. wouldn't matter bolt-on or stud replacement type though if that is the case.

They shouldn't if installed correctly. Thus make sure you install the spacers and wheels with a torque wrench.

Spacers against no=spacers with the same wheels will increase the track.

For the front wheels, you are pushing the centre of the tyre tread further outboard of the point at which the steering rotates which implies the scrub radius will be increased which will increase steering loads and alter the turn-in behaviour on the track as steering induced camber gain can be affected. In DD, you might notice the car is more susceptible to "tram-lining" or following trucks ruts in the tarmac.

If you are not familiar with the term "scrub-radius", Mr Google can help.

Kenchan is also correct in that the vehicle will see a slightly reduced spring rate at the wheel as the centre of the tyre contract patch is further outboard of he spring pivot on the lower arm - again, not likely to be significant with 20mm spacers.

The root cause of the "pulls right" could be a function of slightly increased track - the tendency was always there but the track increase has accentuated it enough to become noticeable.

A car that pulls one way needs to have alignment checked in any event (camber and toe as a minimum), although caster can only be adjusted with adjustable FUCA and your post does not mention whether these are installed.

That's not spec! I'd go higher than the wheel spec. Mine are 100 with loctite and wheels are 90.

I read spec was like 76 or so, i got a cheap wrench highest is 80 for 3/8 drive.

Guess i can take wheels off and torque to 80 and give it a extra umph with a regular lug wrench.

I just saw it on discount tires site. Nissan manual does say 80 now that I look. I've always done 90 so can't stop now as the studs stretch. I do want my spacers tighter than the wheels though, call me crazy.
