Correct way to measure wheel spacers?
 

I have a set of wheel spacers and the fronts are thinner than the rears.

They were in some H&R boxes and they look alot like the ones on the picture, but I want to be sure what size they are.

Most likely they were used with stock wheels and a turbo body kit made for a 911sc.

Thanks.

A picture is worth 1000 words...
 

51/2" - 33/8" = 21/8"

OK, would that be 2.125" ?
Now to get a measurement in Millimeters........

don't see why you'd measure the bell of the rotor as well
or how it's difficult to measure a wheelspacer, but hey...

2.125" x 2.54 = 5.39cm = 53.9mm

OK, Well Thanks.

The photo was for something else... A caliper on the spacer alone is the correct way...

Anyone have any ideas what the size is on these two pairs???

Looklike...
 

17/8" and 1"

If they are on the rear (or front), don't worry too much about the difference (left/right)... These car were hand build :D;):D

So that would be like 25 & 48 mm?

Yeah 25mm & 48mm is the metric equivalent of 17/8" and 1".

They might not be exactly that because we are doing this from a photo.
