Hi guys probably a commonly asked question but I'm really new to wheel offset and changing wheels and needing adaptors etc

Long story short I am changing my current setup from 220M wheels 245/35R19 front 265/35R19 rear . Wheels I bought have 34 et in front and 37et in the rear. I want to keep the standard 29/23 et with these new wheels. So technically speaking a 15mm spacer in the rear will change the et from 23 to 22 and a 5mm spacer in front will leave it unchanged at 29.

Question is - surely there is no need to change the bolts? The exact size bolts I currently have will work ,right?

Appreciate all inputs

If you're using spacers, you should get longer bolts.

So even though the spacers will bring the offset back to the current offset?

Yes you do, because the spacer is adding material to the wheel.

Chart is from bimmerworld site.


Bolt Spacer
32mm 5-8mm
35mm 8-10mm
37mm 10-12mm
39mm 12-15mm
42mm 15-18mm
45mm 18-20mm
47mm 20mm
