Can you run different spacers on a 4wd?

Is it okay to run different spacers on a 4wd? (Toyota st205)

Ie 25mm on the front and 20mm on the back?

[Leon]

Yes

All of them need to be certified though.

Excellent. I just want to no if it will cause the car any grief..

As. Ive heard "its bad to run different width spacers" and ive also heard "the front track is allready wider so different size spacers would not hurt"

Just want to be sure

The thing that messes with awd cars is different rolling radius of tyres

I can understand that.. Diffs would fight each other. Just want to check that spacers dont effect anything that im not aware of
