Some people will decide to live with it. For me, I won't settle for worse drivability than before the springs so if the bolts and playing with the alignment don't fix it I will go back to stock springs. I love the stance right now but it's not worth it.

Honestly it's not terrible but it does want to go right, worse than just the crown of the road. I've got to keep pressure on the wheel to keep it straight.

so is it the camber bolt you need also saw mention of a castor bolt? Where do you get these?

Adam Chambers

they are all the same bolt. Two per side on the front. One for Camber, one for caster. I got them at the local dealer, $25 each. Part number 0003331071

The K-Mac front caster/camber parts will have you sorted. It's not cheap though.

don't know much about alignment stuff. So pardon my dumb questions, but why didn't Mercedes include these bolts with the car? They have a spot for them but you need to buy the bolts. I guess what I'm asking is why does Mercedes even have these they don't provide a lowering spring through them. Confused.

Adam Chambers

from what I understand they call them crash bolts. so if stuff gets out of wack it gives a little more adjustability.

AMGonFire

also looked up the part number. Appears to be for a 2011. Would this work on a 2012 as well? Or is there a different part number for that?

AMGonFire

ok makes sense. I would assume most shops who do alignments know what to do with these I'd assume? Let us know how these work out for you. When will you be installing them?

Adam Chambers

Taking it back in tomorrow. I didn't install the Bolts because after talking to the tech he said they may only need 1 or 2 or 3 or all 4. So will have them use whatever they need and then return the rest.

AMGonFire

how bad is your pull are you fighting the wheel?

Adam Chambers

bad enough where if I am on the left lane on the highway with the crown going to the left it still wants to drift right.

Adam Chambers

I took it to Mercedes this morning. They had to use 3 bolts, to correct everything and now it is driving straight. Ended up costing a total of $350 for the alignment/3 bolts/labor.

AMGonFire

good to hear! So you would recommend going to Mercedes over a Indy shop?

Adam Chambers

Unless it's an Indy shop that specializes in Mercs, yeah I think dealer is your best bet. Save headaches and get it done right the first time.

Mort

It really depends more on the ability of the tech at whatever shop you go to. I took mine to our local dealer and he put the bolts in fine but not so it would reduce the pull from being lowered. Just excuses from him after that. You need to got to someone that knows what locations to put the bolts in to reduce the pull.

Adam Chambers

Agreed. Mechanic at my dealership was awesome. Noticed me leaving in the car and came out and talked for a while about how he got it all set up and why there was an extra .5 hour charge on there to remove the sway bar to get one of the bolts in. (Something I didn't even question) Pretty happy with my dealer.

Really would like to drop my coupe and do spacers but so many people saying the car pulls right has me concerned.

If I get two of those bolts the issue will be resolved?

I'm another C that pulls hard to the right.

I had H&R springs installed and the car pulled slightly. Gave them a couple weeks to settle.
Last week, I had 4 new tires mounted & balanced and alignment done at a highly recommended shop.
Mechanic drove it around the block, comes back and says it's a "little floaty, give it a few hundred miles and see. If that doesn't help, swap the fronts, sometimes the tread prefers to roll in opposite direction."
I don't find it floaty at all. It's clear the car pulls hard to the right. Worse than before.

Gonna swap the fronts tomorrow and see if that makes any difference. Also want to check control arms and bushings. Maybe something is bent that I don't know about. I am the 2nd owner. Carfax shows 1 rear end collision.

Also, not sure if it matters, but as I took this picture, I noticed the car info is wrong at the top. Printout says "CL...NOT M156"

Sorry to beat a dead horse, but these camber bolts are the remedy?

tpliquid

Did they say where the 3rd bolt was installed?

i assume 2 were for camber

Hey all, I've got a new-to-me '09 with 64,500 miles and in the few weeks of ownership, I've noticed a healthy pull to the right. At first I was paranoid it was because I swapped on a CF wheel and perhaps misaligned on re-install but I can tell it's partly the road crown pulling it. I have stock springs, brand new PSS in fronts, and 18". Can anyone offer any expertise on whether the crash bolts would help sort it out? I mean, please correct me, but even if you have perfect alignment, shouldn't your car still pull right on the road due to the crowning effect? Should I also try and move my steering wheel another notch right?

Just got my C63 aligned after an H&R spring install. It tracks straight now, but I'd like to correct the camber specs. Does anyone know how many crash bolts I need and where do I put them? Thanks in advance

You can get 2 or 4. Putting 4 in will also play with the caster which will reduce camber a bit but not much,

curt.r

I'd like to correct the camber as much as possible. More likely though, I'd like to get the driver's side camber close to matching the passenger side. Mort suggested I install one crash bolt to adjust my driver's side camber by +/- .3 degrees to get it closer to matching the passenger side. Do you know where to install this bolt? I've read that the install is fairly simple but I have yet to see where people install the crash bolt

gtracer

Fairly self explanatory once you get under the car. Its the arm that would add or reduce camber, the other would affect caster. You're essentially changing the bolt that holds the arm to the subframe. The slot in the crash bolt allows for a slight change.

I'd buy 2 of them so that when you get realigned, if need be you can put the other one in and save yourself another trip to get aligned.

curt.r

Okay, seems pretty self-explanatory once I get under the car. I'll shop around and see where I can find the crash bolts the cheapest. Thanks for your help!
