Shim for 225 rear tires

[Bitsyncmaster]

Since the 225 tires would have a little more fender clearance, why not add a shim under the wheel to bring the stance back to what the 235 tires are? Then there would be no visible indication from the side view the tires are smaller.

that shim would only be 5 millimeters wouldnt it? because the difference is 10mm, 5 from the inside and 5 from the outside of the tire/wheel...not sure it would be noticed...

Yes it would be very marginal to see the difference.

And you would have a couple less threads of engagement on the lug nuts. The factory shim has probably used up that margin.

That reminds me. I don't think I have any factory shims with my car. Is it just a plate under the wheels?

you could just stick a few washers under the wheel to take up that gap...

NO. The wheel must be against something solid, not spaced out by some washers.

Really? I've always noticed on at least 1 side of my car, I am missing a counter-sunk screw...but never knew what it was for. Apparently I'm looking at the shim & it's rusted fast to my brake rotor.

Any idea if this is simply to gain wheel/tire clearance (i.e. in the area of the lower shock mount as I believe it's pretty close) or for something else? Would there be an interference if you were missing this factory shim.

I just looked and I do have the spacers. And yes it looks like the wheels contact between the studs. The spacer is held on by one flat head screw.

I do not believe I have these. What is the purpose other than to move the wheels out slightly?
Do I need to buy them Dave?

Go out and take a rather spirited drive (i.e. lots of corners taken somewhat aggressively but without spinning the car). If you see drag marks on the rear wheels or tires from the lower shock mount, you need them. Otherwise they are optional but were intended to be on all cars.

I take it back that the shim contacts between the studs. What I saw was where it does not contact. So the wheel contacts around the studs. I don't think I would trust just shimming with washers.
