Help wheel spacers

[sp84]

I have a audi s3 on a v reg and it has 19 inch audi rs6 reps on it what would be the best size spacers to use to push the wheels out in the arches thanks.

Depending on the offsets of your rims, I'm guessing they are ET35, then 5-10mm up front and 10-15mm rear would be ideal.
