Wheel Spacers
I'm looking in to install some spacers to my rear wheels.. but I'm a bit confused by how big a spacer i should use.. i have the evolution package on coupe meaning i have 225/45/17 front and back, but i'm putting on 245/40/17 tires in the back soon so i get that sick look of the amg coupe (yes they will fit, i tried).. but i'd still be missing those wider rims. The coupe has 7.5 inches front and rear rim, the amg body kit coupe has 8.5 rears. So if 1 inch = about 25 mm... i could use 25mm spacers on my rear wheels without any problems... but i don't know maybe i'm missing something, i feel i am.. any hints/thoughts?

Also, if you really end up going 245 and push them out another 25mm with a spacer, then you will probably have rubbing issues when the car has two adults in the back.

You need to consider the offset of the wheels in addition to the extra width of the wider tires too. The C7 wheels you have are 37mm offset all the way around. If you look at stock wheels in the staggered configuration - where the fronts are 7.5" width and rears 8.5" - you'll find the rear offset is 30mm. IMHO I think you'd want 7mm spacers if you're going with 245's on the rear. If you were going with 225's all around and wanted to push the rear tires out then I'd go 17mm spacers (7mm offset + 1/2 the 20mm wider tire). You'll want longer lug bolts to accomodate the extra width of the spacers.
25mm spacers will push your wheel/tire out a full inch, and I would think you'd be rubbing even with 225's.
I have the same wheels which I like very much and was considering the same thing to get the staggered effect, but found a set of staggered wheels so went ahead with those. I'm still curious how that would have worked out, so please post some pics when you are set up!

first, superbee, what didin't you get the amg coupe bit or the 8.5 rears and 7.5 fronts?
Second, kickR, i still might go with the 235or even stay with 225s, i guess i'll have look into that more, and after measuring up with sport sedan there is about a 20mm difference between how much he's wheels stick out than mine..
mtnman, i'll have to check out the offset too.. and i just love the look of the c7 rims on the coupe.. i just can't find rims i like better than the ones on it, still looking though.. i did find lorinser replica rims that look sick on the coupe and are staggered too, but they are just a bit too expensive..
i think i'm going to see what size tire i'm going to put in.. if its a 235 or a 245 maybe even stay with 225s.. then see how much i can go with the spacers, probably go with 10mm or 15mm if i stay with 225.. you guys think its possible that i go with 20mm with my 225?

Hi Daniel,
I have 20mm H&R spacers on either side at the back and am happy with the distance.
Pics here : https://mbworld.org/forums/3103989-post37.html
Hope that helps...

you were talking about the coupe rims then suddenly talk about the amg body kit??
if you were meant about the amg rims then you dont need any spacers what so ever and you can stretch the tires till 235 @ the front and 255 @ the rear.. even if you are going to put spacers... but most probably not that thick...

c230 brit thanks for the pics, they look sick dude.. do u have any rubbing issues.. because if not i'm going with 20mm for sure
superbee.. when you buy a coupe from mercedes with the amg body kit.. you get staggered wheels with it, thats what i know from my friend who has an amg body kit coupe.. but since i don't like the look of the wheels on his car.. but i love how wide they are, i'm just trying to get as close a look to his car that i can with my stock rims.. but your right i wouldn't need spacers if i had staggered rims

C230Brit - are you running longer lug bolts on the rear with the 20mm spacer and if so where did you get them?
As I mentioned earlier, I have a staggered setup on now with 245 rears. I'm digging the beefier look (fills up the rear wheel well nicely), but I'm wondering how much the gas mileage will change (yes I'm a geek, gas mileage matters). I still haven't thrown out the idea of spacers with 225's on the C7 wheels...

c230Brit i'm going to go with the 20mm for sure i'll post up pics when i get it done, but i won't do it this month though.. i'm doing my interior in carbon fiber this month(not cheap)
mtnman, good luck with that.. but if u got staggered rims with 245 i think spacers will pretty sure give u rubbing issues.. because your rear rim is for sure an inch bigger than the C7 rims
Superbee, ya the amg kit is sick.. i'm getting that done hopefully by the end of this year.. cool setup with the quads btw!

Edit: please let us know where you get the longer lug bolts to accomodate the spacers.

Actually, the lugs came with the spacers in my case...but yes, you will definetly need longer lug bolts. I was due to put the summer wheels (and spacers) on again this weekend. I'll try and see if there are any part numbers on the lug bolts, etc
