Are 25mm rear / 15mm front wheel spacers too aggressive
You just need the basic measurement on you car, and you can calculate any combination, see if they fit.

So am I missing something in terms of wheel bolt length? It should be really simple, right? Assume that your factory wheel bolt is 27.9mms, and round to 28mms for simplicity. If you put a 10mm spacer on your car, then the wheel bolt would been to be 38mm (=28mm (OEM wheel bolt length) +10mm (spacer length)). If you put on 20mm spacers, then you would need 48mm wheel bolts (=28mm (OEM wheel bolts length) + 20mm (spacer length). No?
Also the Airmatic do lower the car during ride, so that a pot hole can damage your fender and tire. Worst case your tire explode.
I have a W211 Wagon myself, and due to the above, I stay inside the wheel arch.
Even if your car don't sink right now, it only need to do it once, and your fenders are ruined.
Try the wheel calculator, and measure out your car.

This is mine after 3 weeks.
When i got them they had the bolts included but it was a couple years ago, they may have changed their policy. I would give them a call or shoot them an email and ask. I'm sure they'll take care of you!
But the reason is partly that the tires are oversize 265/45/18.

Sounds like running 20mm with airmatic could be dangerous. Looks like a smaller spacer would be better/safer. Maybe 10mm?
