Mercedes C240
New to MB

Recently I got a 2003 C240 base, and I've been looking into modding so I'll be on here quite frequently.
The first thing I want to take care of is wheels.

http://varrstoen.com/products/es-2/

These are the rims I want in 18"
The specs are 18x9.5 +12 offset 5x114.3 With a center bore of 73.1 and that's where I run into my first set of problems.

I was wondering the following:
1) If there is any way I could change the lug pattern to 5x112 safely.
2) The center bore for my car is 66.6, is a larger bore a problem?
3) The stock offset for a MB is +35? So will I encounter a lot of problems?

Thanks for reading, and again I'm very new to the community so be gentle! Hahah

MCRF,

Congratulations on your C240!

1. Safely, honestly no. You could have them filled and re-drilled or you could run a adapter from 114.3-112.
2. As for the center bore, just the proper hub rings would do the trick and fix that.
3. As far as the +12 offset, it will just be poking out of the fender a bit. The lower the offset, the more the wheel will stick out of the body and look wider.

I hope this information helps you choose your new shoes for your C240.

-Alex

Thanks Alex!
I guess I'll keep searching around, I really don't want to run anything that isn't 100% safe as it is my daily for now. On to a suspension question. I've been looking into H&R Springs on Koni Shocks. I want a 1.5-2" drop at max, not looking for the hella slammed, just want to get rid of the gap in the wheel well. On stock wheels this won't give any problems with the fender right? I come across a lot of speed bumps, especially in my neighborhood, that's why I ask.

You should be fine with the stock wheels because you wont be "slamming" the car. So not a problem. Its also a good idea to upgrade the shocks while adding lowering springs so you should have no problem there!

If you would like help with the H&R Springs or wheels, PM me i can go further into detail.

Don't forget about other components that go into lowering ie. different size lug bolts, spacers, camber arms, tire/wheel sizes.

This is why I really haven't wanted to lower my car yet.

I'm aware of the spacers, camber arms, and wheel sizes; but I am not aware of the lug bolt size. Could you elaborate on that?

Our cars use lug bolts instead of studs so when getting new wheels you have the correct lug bolt length and correct seat head. Some wheels use tapered/acorn or ball seat. Mb use ball seat on the OEM wheels.

That's why phister's next post would be recommending that you get a stud conversion, so that you in the future could use lug nuts instead of lug bolts. Makes getting new rims much easier.

There are plenty of places to get them. I got mine here:

Rogue Engineering
as they're right down the street from work for me. I forget where phister got his from - you could search his build thread and find out. I'm sure others here have gotten their kits from other vendors as well.

Around $100 for a kit. Saves you a ton more in lug bolts over time, though. And more importantly, you'd be able to get pretty blue lug nuts like phister has.

Thanks Tommy, I'll look into it asap! So switching from bolt to lug nuts and studs is the first on my list.
Is it DIY friendly?

Yeah, you apply a bit of locktite onto each lugbolt, tighten them, leave them like that overnight if you're so inclined, then put on the wheels and nuts. You do have to worry about the seating - OEM are ball seat, some aftermarket like mine (OZ) are also ball seat, but most are cone seat (or also called tapered). So you may need two separate sets of lugnuts if you go from one type to anohter. And don't forget the spare - if you do get the conversion, you'll need a set of 5 ball seat lugnuts for the spare, you can put them where the spare lugbolts were in the trunk/hatch, since you won't be needing those anymore.

Also, if it's important to you, aftermarket cone seat rims have many more options available as far as lugnuts, so if you have a choice, better to go cone for the bling factor.

EDIT: Add your location to your profile; it will be easier for others to answer your questions that may be location-specific.
