I rode your article... But my hub center makes the perfect fit.. So perfect that wheel is hard to get out after release the lugs..

Today I made a metrologic study to the back spacers..
I used a CMM, it is coordinate measure machine wich has 2 microns accurancy.
Made a program and all measures were made on cnc mode .

CMM - Mitutoyo Apex C:

Back spacer:


The study was based on 3 items

- Concentricity:
Between exterior circle, interior circle and a circle that passes in the center os the 5 holes where lugs will screw.
RESULT: 0,05 - 0,06mm

- Diameter:
Diameter of the 5 holes - >74.050mm

- Planicity
Planicity of the surface that touch the disk hub. +/- 0.140mm


I am not sure is these results proves that are the cause of vibration.. But These values are a bit big for normal automotive tolerances on these subjects..

Will send to my spaccers supplier and try to have a conclusion..

That all to the help..

maybe the spacers themselves arent balanced....?

Other than that I'm not sure whats going on. I didnt have any problem running H&R's.

Def best to contact the company then, maybe send them the data too...

get back to us with this though... be really interested as to the cause!
