W203/CL203 Aftermarket Wheel Thread - All you want to know

) without risking issues, and still the clearance issues might persist (not to mention the calliper issue voiced earlier) because of the additional rim width ...... for example:9" = 228.6 mm, which given an ET (positive offset, or in other words an inset) of 37, means that the rim will extend a total of 151.3 mm from the face of the hub back towards the suspension strut
assuming the original wheels were 7.5" (190.5 mm) and ET 36 (these ones) then your looking at 131.25 mm from hub face towards suspension strut.
If my calculations are correct, with the 9" rims on the front, they should extend further out than the 7.5's by 18.05mm
That's a difference of 20.05mm closer to the suspension, before you take into consideration the tyres and any increase in width that you might see from them, although with 225's i doubt you'd see the section width extending past the rims at all, with 235's you'd see some extra width, in theory 6mm extra towards the suspension on top of the figure above, and an additional 4mm further out from the edge of the bodywork.

it would totally suck if the wheels still stick out as much as my work vs-xx's. i don't think it will. my old vs-xx's had a really bad face to have a aggressive offset. with a et38 i needed a 15mm spacer to BARELY clear the caliper

it made no sense because when i had these HRE 540r with et 37 offsets.. it cleared the calipers with a good amount without any spacers
ideally i'm looking at 235 + 5mm spacer in the front?

21.05mm closer to the suspension
and
27.05mm further out
that's working on the sectional width of the tyres.
so the vx's were ET38 and 10" wide huh, and you used a 15mm spacer

holy crap, no wonder they hung out like big freaking ears !!!
Lets see, ignoring the tyres, because they were too small for the 10" rims anyway, and their sectional width was less than the rims....
10" = 254 mm
ET38 = Inset of 38 mm
15mm spacer gives -15mm
so, 254/2 = 127mm (mid point)
therefore, 127+38-15 = 150mm from hub face to inner face of rim
and
127-38+15= 104mm from hub to outer face of the rim
therefore your new wheels should be 1.3mm closer to the suspension than the VX's yet stick out 26.7mm less (assuming no spacers)
EDIT: because your previous wheel/tyre combination was only 1.3mm different to the new one and assuming no clearance issuses, you might get away with no spacers if you can clear the callipers

Was just wondering what the fitment would be like.. especially on the front.
Cheers.

Don't stretch tyres - it is an extremely dangerous practice.
What profile tyres can you get away with on the front on an 18" rim? Looks like 40's would be very close!

When it comes to profile you need to keep the rolling circumference front to rear within about 2%. Otherwise ESP, BAS etc. will go mad. Use revs per mile tables on the Tirerack site to check this for various sizes.
I thought i'd ask you guys first due to my lack of MB experience.
They are rotiform BLQ wheels
18", 8" wide and an offset of 45.. Will they fit and if so will i need spacers to make the rim in line with the fender/arch(as we say in England
).Cheers.
