HI everyone I am new to fitment issues
I can use your help. and i plan on contributing as well.
so here is the deal i am trying to put these 20 inch rims on my car but i need to modify some things to make it work.i have vossen cv1 20x9 for the front and 20x10.5 in the rear.
looks like i will need a 1 inch spacer in the front and almost 3inch in the rear?
what parts and lugs should i get and has anyone have 20 inch wheels on there ride?

looks like i will have to do a wide body kit which i didn't want at first.
I don't think spacers will work as the wheels are already sticking out based on your pics. 20" wheels would work with your car but with the correct offsets and tire sizes. The Vossen dealer should have recommended the correct offsets to begin with (assuming you got these wheels new). To start - what are the offsets on those wheels and what tire sizes are you looking to go with?
The rims i got used for an awesome deal from a family member. The came off a 2011 e350 coupe.
The rims i got used for an awesome deal from a family member. The came off a 2011 e350 coupe. I am not sure about the offset i have to check when i get home.
I looked of the clk63 black on tire rack to see the specs. I wanted to see if it would b flush if i get the body kit.
The clk63 20 inc specs were 20x9.5 front 20x10.5 rear
I will post some better pics later

that is about 30mm in the front and 70mm in the rear.
with no luck i decided to search for some one that can make custom spacers.
i found this website based in Cali
i am waiting to get paid to take my exact measurements. and put in my order.
says it take 5 days to make then how every long it takes to ship depending were u are.

so after some close review in the garage an putting stock wheels back on. i took a closer look at the clearances between the tire and rim in relation to the strut. i discovered that the tolerance is pretty close.i then re-evaluated my measurements. i came up with 1/2 of an inch(12.7mm) minimal for the front possibly stretched tire.
as for the rear i came up with 1.5 inches(38.1mm) minimal possibly stretched tire.
so to be on the safe side i decided to go with the H&R wheel spacer kit with the specs of_____________ to be on the safe side
FRONT 20MM THICK (0.787402)INCHES
REAR 40MM THICK (1.5748) INCHES
COST £166.77 ($181.5)
INCLUDES EXTENDED STUDS

ALSO AFTER DOING A MOCK UP LOOKS LIKE I CAN GET AWAY WITH SOME EXTREME FENDER ROLLING. I WOULD APPRECIATE SOME RECOMMENDED TIRE SIZES AT THIS POINT.
THE OFFICIAL WHEEL SPECS
VOSSEN CV1 BLACK MACHINED FACE POLISHED LIP
FRONT 5X112 20X9 ET32
REAR 5X112 20X10.5 ET42



so i went to tirerack.com and i punched up clk500 to find the maximum width tire rack allows for 19 inch rims.
so here is the math. they recommend:
FRONT:19 X 8,5 ET 32MM REAR: 19 X 9.5 ET 35MM RECOMMENDED.
FRONT:20 X 9 ET 32MM REAR: 20 x 10.5 32 42MM CURRENT WHEELS
So i came up with a formula to space the wheels accurately. with out pasting the width that's actually needed.

FRONT MATH
9in -8.5in = .5in
The off set remains the same so i need to space the front by .5in which is 12.7 mm they do not make a 12.7 mm spacer for the clk. the next best thing was an hub centric 15mm spacer by bloxsport. 15mm= 0.590551in so i will have slightly more room then .5 in
REAR MATH
10.5in - 9,5in = 1in also Et math 42mm-35mm = 7mm
1in= 25.4mm then 25.4mm + 7mm = 32.4 mm
so i haven't found a 32.4 mm spacer or 33mm how ever i did find a hub centric 35mm spacer for the clk by bloxsport.
35mm- 32.4mm = 2.6mm
so that's only an 2.6mm increase over whats recommend
With this setup i will hope to get away with rolling and flaring the stock fenders. (no wide body kit)
i will be ordering this Friday stay tuned to see if this works out.
also i will be documenting my build on you-tube channel smoovmedia.

i ordered my camber arms from a member on here by the name of ghostrider a few years ago but i'm not sure if he still produces them. Jay @ MBArts makes some nice pieces and he has the two you will need to help you get everything squared away by using his toe arms and camber arms.

any other questions you might have feel free to ask or reply on here and i will try and answer to the best of my ability and personal experience.

[QUOTE=sweet jones;6694146]these are some pics from my previous and daily setup .

How can i verify this and what are your sources? i can afford to order the wrong stuff.
But with ur theroy i can reduced my final calculation in 1/2 and that is very appealing. Then again i find it hard to belive then this would mean the offset is zero

[QUOTE=Yidney;6694309]
This link sweet jones gave me suggest that yidney advice is right regardless of the off set.
Approximately 1/2 of my original calculations

But as you can see, if you plug in the numbers for the rear into the calculator, you get exactly 20mm, which is what I got doing it the long way. The calculator is great, but it's also good if you think it through so you understand how it works.
So then i will be ordering
6mm for the front and 20mm for the rear.
