I joined mb world and i am currently modding my w209 v8.

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.

Welcome!

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?

I spaced the wheel on purpose to meause how much of a spacer i would need . And also to see what kind of fender flare i would need to compensate.

The rims i got used for an awesome deal from a family member. The came off a 2011 e350 coupe.

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

Cool. Good luck. Look forward to seeing pics when you complete this mod!

i have been searching the market for wheel spacers. that meet my needs and i had no luck. i need about 1 inch in the front and 3 inch in the rear.
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. that can make them . http://www.ezaccessory.com/Custom_Ma...ters_s/178.htm
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.

gixxerboy

Damn they are big *** spacers. I personally wouldnt use something that big. So do they bolt to the car and the wheels bolt to the spacers independently?

smoovmedia

According to the guy that will make them. The spacer will be bolted to the hub and the rim will be bolted to the spacer.

I'm a little unclear on your priorities. If you had 20" wheels that were a perfect fit, would you still want a body kit anyway? Or are you considering a body kit only because you have wheels that are not the ideal fit? If the latter, seems like an expensive way to address that issue. Wheel size is a matter of taste if you are ok with any handling or ride differences, but there are a number of opinions that have been expressed on the board over time that anything larger than 19" just doesn't look quite right on a W209.

smoovmedia

I was getting a body kit regardless but i didnt want a fake black edition ... but i am considering it because i like the way the rims look with such a wide rim.. and i dont think fender rooling wheel be enough to compensate. I dont want the tire. Throwing dirt all over plus in my opinion the black edition kit is the only widebody that looks good to me

smoovmedia

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
http://www.ebay.co.uk/itm/H-R-wheel-...0AAOSw6EhUNhkU

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

sweet jones

Those H&R spacer sizes seem about right but you will have to fit the wheels with those to figure out your tire sizes. I am currently running 19x9+6 front and 19x10-0 rear but am using a rear camber kit and just got some new MBArts adjustable rear toe links that will be installed soon but the fitment seems nice and how i like it. your previous calculations of 30mm fronts and 70mm rears was pretty wild and glad you didn't go through with ordering those big paper weights.

smoovmedia

lol even better news.
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.

sweet jones
were can i get the rear chamber arms you are talking about?

sweet jones

no need for a widebody kit with the sizes you plan on running. a good roll and a pull should give you enough clearance but you also need to take caliper clearance into account for the front wheels, depending on the face of the wheels you will be using. if you're going the spacer route, i also decided to convert to 90mm wheel studs which may have been a bit much and 75mm should work just fine. I also would take any info from tire rack lightly as they are very conservative with their fitment calculations.

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.

sweet jones

these are some pics from my previous and daily setup i will be putting back on soon. the size for those wheels is 19x9.5+35 all around. i used 15mm spacers up front to clear the wheel from hitting the strut and i used 30mm for the rear.

19x9.5+20 225/35/19 front
19x9.5+05 235/35/19 rear
90mm extended wheel studs

Yidney

On first read, I think your science may be a bit off. When you change from one width wheel to a wider wheel, and your concern is whether the wider wheel will rub your struts, etc., you only need to be concerned about half of the increased width. You have added in the entire increase in width in your formulas. When you add an inch to the wheel width, it gets 1/2" wider toward the inside, and one half inch wider towards the outside - in other words, it grows a half inch on each side of the center line of the wheel. So it's only getting a half inch closer to your struts. And a half inch closer to your garage wall. So i think you can reduce each of your calculated amounts by about 12mm.

smoovmedia

Awesome ride man and i was looking at the same grill choice thats the (morello) i believe. I am stuck between that and the sport sl grill.

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

Yidney

For the heck of it I just ran your rear math based on what I said above. On the recommended setup, the mounting surface of the wheel is 155.65 mm from the inside edge the wheel. That is 1/2 the total width (120.65mm), plus 35mm offset. If you add an inch total width, but only 1/2 inch on the inside, the 155.65 grows to 168.35mm. A difference of 12.7mm. Then add to that the additional 7mm offset (42-35mm) and you get a total difference of 19.7mm. So you need a 20mm rear spacer, not 32.4mm.

sweet jones

These also may help you out a bit as well.

So let me get this straight if the rim in the front is overall .5in wider u mean i should only calulate only .25 in spacing to compinsate which translates to 6.35mm ???

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

Yidney

Yeah, really not a theory - you just need to think it through. Your assumption about the full width is a common mistake. Another common error is that it can take a while to grasp that the larger the offset, the closer the wheel sits to to your struts. Just seems counter-intuitive. Just don't forget to add in the difference in offset. Written out, the formula would be "SPACER THICKNESS = 1/2 increase in width + difference in offset."

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.

smoovmedia

I im very greatful for this information and everyones input .
So then i will be ordering
6mm for the front and 20mm for the rear.

Yidney

Before you order 6mm spacers, I would test it in actual application. You have calculated your needs based on a theoretical recommendation about 19" wheels. But the unknown is how much space between the tire and strut there is under that set up. If you stick on your front wheel right now with no spacer, does the wheel hit the strut? If not, how much space is there? If yes, then stick a couple strips of wood 6mm thick on your hub and hold the wheel up. How much space is there now? Enough for a tire? The reason I'm raising this is the 6mm spacers won't be hub centric. They say they are, but I think that just means the bore is the correct size. If you stick 6mm on your hub, what is left for the wheel to sit on? Anything? That can create vibration issues. Your thick rear ones are true hub centric - they have a shelf machined into them for the wheel to sit on. You need at least a 10mm spacer for that.

smoovmedia

Yes it does touch and i will test the wood therory. Also the original hub on the front protrudes almost a 1/2 of a can soda out i will take a pic when i get a chance to show u what i mean.

Yidney

Just saying that if you are hitting now, and since 6mm is only a quarter inch, 6mm may not give you enough space with any normal tire. You might want to go to 10 so you can get hub centric spacers. As for the half soda can, I know the bearing cap and everything sticks out a ways, but all that matters is the largest diameter the wheel actually fits tight over. That is only about a quarter inch.
