Hello fellow SL-owners,

Just purchased a SL55 with some 20 inch wheels on right now. I plan on buying new 20 inch wheels and would like some suggestions on what works. I have searched a bit but anyhow would like som more input.

My setup right know is 20x35x255 front and 20x30x275 in the back, dont know the size of the rims other than that they are 20 inch (ET etc) unfortenately, picture below (black one). I plan on going 255x30x20 in the front and 285x30(25?)x20 in the back.

- What is the recommended size for SL55 when going on 20 inch wheels? 8,5x20 and 10x20 or is it possible to go bigger? And what ET do you suggest?

I want a look that's shown in the attached photo (silver one). But please let me know that you think!

My car is now stock ABC-suspension. I plan on doing a very very slight lowering but nothing extreme.

Many thanks in advance!

the wheels you have look like fake amg wheels. You have to know what size they are before you buy tires. You go by wheel size, not just what you want to put on them. So youll have to look and get the size.
I have some lowering links if you want to buy some.

GusOsc

Thanks,

But I will buy a complete set of new rims and tires, not tyres to put on my old rims.

I have searched a bit and what I can se is that 255/30-20 on 20x9 et25 and 305/25-20 on 20x10,5 et25 will fit?

How much is it possible to lower, I'm looking for a modest lowering of around 20 mm or so. Is it adjustible with those links?

Thanks.

Found out that maybe some lowering module is the way to go.

Anyone who have hade any experience with: http://mesablackworks.com/suspension...dule/LoMo%20V2

Looks nicely priced at $475.

Any other suggestions of modules?

Thanks.

yes those wheels tires are right and links or module does the same thing one just costs 5 times more. heres what those wheels tires look like with links

I've got some sweet HREs that would fit perfectly! PM me your number and I can send you a pic of them on an SL55.

Thanks,

But I guess that modules give you a opportunity to by remote choose the hight. When fixed links one has to do it in the garage to adjust.

20x9 and 20x10.5 with 255/30/20 and 305/25/20. I've run this setup on a handful of different SL55's and is a great fitment.

GusOsc

Thanks B Feelgood.

Did you utse lowering links or a module together with that set up? I've seen most 305/25/20, on those big 305's, any special reason to go with 305/30/20?

Thanks.

B Feelgood

You're correct sir, that was a typo. The 305/25/20 is the correct size. I've used the lowering links every time with no complaints. The bigger size tire definitely aids with traction first and foremost and secondly it just looks aesthetically more pleasing from the rear.

okbarnett

well, youve got 3 height sets on the car already. low which you dont want to drive on because you probibly will be scraping regularly, med which is a little lift and is sort of safe but still gives a low look, hi which you want to set the alignment on and gives the safest clearance plus makes the suspension as square as possible and makes tires wear as good as possible, you want to drive on hi usually
Once I used the links and got them set, I never wanted to change them

GusOsc

okbarnett,

So you mean that with lowering links, the hight adjusten on the ABS-suspension set to medium (one light) the ride will be a bit lower than the original ABS-suspension set to low (no lights)?

/gustav

okbarnett

it depends, there is no normal when you use a link or module, you are taking control of the height and making your own settings. So you could make it higher than stock or lower than stock.

Maybe consider 20 front 21 rear if you are considering going larger. Just a personal preference, but I like slightly larger wheels in the rear of most cars as it adds something extra in appearance. To me the SL body style is a big blah, so it needs a little bit of something to make it a bit more exotic. Mine is lowered too, and all is fine with no rubbing (Mine is SL65, but I assume SL55 is the same as SL65 regarding body when considering wheels/tires). Photos are in the link below of what my 20/21" looks like before and after the original 19":

Thanks for the tips abort the 21 och rear option, looks really nice.

Unfortenately I think I will stick to my initial idea with something around 305/25-20 in the back and 255/30-20 in the front with respectivly 9x20 and 10,5-11x20 rims.

If you like the design of the wheels shown above they are fully custom meaning we can make them for you in 20"x9" // 20"x10.5"-11" no problem. Shoot me over a PM so I can give you a few looks at various ideas.

okbarnett

if you havent had a SL before, you will have to align it after you do any lowering. Get all the heights like you want it, then set it on hi and have it aligned. It will need the camber bolts in the front, they are adjustable, you will have to have them before the front will come into alignment. the rear doesnt have any camber alignment so you have to take it as is. (unless you want to spend $1000 to 2000 to add parts) so after it is aligned the hi setting will be the best possiblity your car is capable of to have straight, square alignment. Thats why you can drive on hi and not wear out your tires quickly and have a fair handling alignment

GusOsc

Thanks,

But can you explain what you mean with "it will need the chamber bolts in the front"? Do I need any new parts or do I need to adjust those chamber bolts after installing and adjusting the lowering links to my preference?

/gustav

okbarnett

if you car doesnt have them, you will have to put them in, almost %100 . they set them for straight up position and thats where they stay , its the only thing to line up the front camber. All mercedes aligners will know about it. bolts cost about $75 at MB
you can do all your height before you do this alignment, it may raise the front a couple mm

Dont know if you got new tires or wheels yet... but i couldnt run 25 series sidewalls without bending my old 20s.

I run 19s now, they look great but im not happy with the tire selection... i do a 255/35/19 up front and a 295/30/19 in back. I think the car would prefer a 285/30/19 but they dont offer PSS in that size for our load rating

GusOsc

Thank you m-svt-AMG, but I will go for 20s.

I have 20s on tight now but 245/35 and 275/30 respectivly, going down in diameter seems not like an option.

For those of you that run 255/30-20 on 9x20 and 305/25-20 on 10,5x20, can you please post what offset you run? Seems like my lokal wheel supplier does not really know 100%.

/gustav

thewb

Is a completely custom forged wheel not an option as opposed to an off the shelf choice that will never fit 100% correct?

desired_speeds

27mm front and rear. The front still has more space to go a few mm lower in offset, but the rear is dead flush with the fender at stock height.

okbarnett

25mm is good for mine, but since you have the wheels are you trying to add spacers
its not going to do anything for you if they are a few mm different so you should avoid using spacers unless it is necessary
