W203/CL203 Aftermarket Wheel Thread - All you want to know
Any recommendations on wheel locks as well?
Can't wait to post pics next week
I'm looking to purchase a set of 19x8.5" and 19x9.5" with a et35, I'm rolling and pulling my fenders, going for a minor stance look.
What size tires should I run, what brands are suggested for a minor stretch, and where is the best and cheapest place to buy these tires?
All of your help is greatly appreciated!!

In terms of tires: Nitto 555, Hankook Ventus V12 are the best deals for what you are getting. Michelin's are the best if you have extra cash to spend. Pirelli's wear too quick but great if you need that extra traction.
Good luck!

I run my car kinda low and stiff. The only time it rubbed was with a full trunk and 5 people in the car.
I had goodyear sp sportmaxxx. I like those tires very much!
@Peydidy: If you have the sportpackage you will need to run and 12mm spacer up front. I had a set of LM reps 8.5x19 et35 and 8.5x19 et35.

The front setup is 19x8.5 and rear is 19x9.5
Another real quick question is how much should I lower it, and which springs should I get?
Teins wont lower your 07 that much. H&R will lower it a good amount but you might need to get #3-4 pads so the rear doesn't drop too low so the fronts look off.

Second opinions/experience and thoughts are always good, so i'd appreciate some other eyes looking over this.
so, quick refresh, i currently have 17" Mercedes Alshain Alloys :-
Wheel part number: MER B66471511
Additional alloy part number: A2034011802
Rear alloy wheels: 17x8.5" ET34
Wheel part number: MER B66471515
Additional alloy part number: A2034012402
And the New Wheels are 18" Brabus Monoblock VI Alloys :-
Wheel part number: BRA 612-858-35-RDK
Rear alloy wheels: 18x9.5" ET35
Wheel part number: BRA 612-958-35-RDK
so, i've been doing a little research at various sites to check out the size differences etc, given different tyre setups, Original fronts are 225/45/17 and Original Rears are 245/40/17.
Given the increase in rim widths i'm looking to go up a size on each i think (subject clearances etc) the rears, can, i know from the AMG option, go straight to 255/35/18 because that is an AMG option, the inset can also be shifted to ET30 as an option, giving 4 mm wider track over the original ET34 with no issues.
One of the sites i have been using, was this one, i have linked it because it puts all the info on the one calculation page (printouts below) Rims'n'Tires
the options i have been considering are,
225/40/18 or 235/40/18
and
245/35/18 or 255/35/18
Given the information, and looking over the results from that website, it would appear that to fit these to my 2005 C350 Coupe i don't actually need any spacers
just the correct Brabus Bolts and high-security locking wheel bolts should i wishThis would be nice, and is backed up a little by this pdf file i found BRABUS_CL203_2005 which, if you look at the table on the back page, seems to indicate all i need is the bolts

(be careful not to get the wrong line in it, as there is a part number the same as mine showing as ET25 in that chart, but the part number is definitely for ET35, so there is at least one error in that chart that i can see)
Here's an image version instead, if you don't want to load the PDF file :-

Here are the printouts with the info from that website for the different wheel combinations
FRONT

REAR

so..... anyone got any thoughts, am i on the right track, or has someone already tried running this combination and found they needed spacers ? ...
the other thing i have noticed, is that in stock guise, with the steering on half to full lock, i dont exactly have an abundance of clearance front or rear of the tyre, can barely squeeze my fingers in the gap

As for tires, 225 and 255 is typical, but if you want less understeer 235 on the front is better.

@Peydidy: If you have the sportpackage you will need to run and 12mm spacer up front. I had a set of LM reps 8.5x19 et35 and 8.5x19 et35.
Do I just need 12mm spacers in the front? and what kind of suspension do you have?
612-858-35 =
612 = Model/Design
858 = 8.5" width (85) and the remaining '8' signifying 18" height (see the 19" rims listed for comparison 859 = 8.5"x19")
35 = ET
Plus, if the ET is 25 and a 10mm spacer is recommended/needed, then that = ET35 ..... which is what i have, so assuming the same rim construction dimensions, and the fitment of a 10mm spacer inconjunction with ET25 results in clearance of the calliper, then mine being ET35 should not need the spacers.
Also, working on the principle that for 225's your looking for a rim width of between 7.5 and 9" and for 235's between 8 and 9.5" ..... and the ones i have are 8.5 then the 235's are going to sit better on the rim, and give more comparable visual match to the rear 255's sitting on 9.5" rims ..... i am not a fan of the rims being too wide visually for the tyre, and i hate tyre stretch !
ET25 = ET35 + 10mm spacer
ET25 + 10mm spacer = ET15, not ET35.

Heres a pic of what they look like:



I spoke with the seller, and he said that they would fit without a hub ring... Any ideas?
