Spacers are fine provided they are good quality like H&R, make sure they are Hubcentric so they fit correctly on the hub and the wheel will sit correctly on them.

There are 2 types

DR - bolt through
DRA - Bolt on

If you are going 20mm (per side) or over then DRA is the way to go, this also saves you buying new wheel bolts.

When buying bolt through you will obviously need longer bolts and you measure these only on the Thread length so measure yours and add the Spacer thickness

I ran spaced wheels on my CLS with no issues , i fitted them to achieve the correct offset with the aftermarket rims.

Is it to alter the look of the car or to fit different wheels ?

If it is the latter then check the profile of the mating face of the wheel bolts as MB have a curved profile and some aftermarket wheels have a tapered profile so new wheel bolts may be required.

Curved are called "Radius Head" bolts

And there are two sizes (technically 3).
M12 with 12mm radius.
M14 with 14mm radius.
M12 with 14mm radius (specialist aftermarket).
It's important the radius matches the wheel.
You cannot fit 12mm radius wheels to a car that use M14 bolts.

Also if this is for appearance be aware there will be increased power on wheelbearings and suspension joints and if fitted to the front will change the scrub radius which can impact behaviour under braking and on bumps.

CL203 will take a 12x1.5 17mm HEX Radius head bolt

Hi
Once tyres are fitted will go down to my local indy and he will advise on what thickness of spacers I need, will contact again once I know.
Many thanks
