Post your C450 with Aftermarket Wheels

MBWorld Fanatic!
When I was shopping the C450 and wasn't thrilled with the OEM wheel options I did some digging into aftermarket. While its great that MB gave it a one-off AMG suspension set up it looked like it was going to be slim pickings as far as aftermarket wheel choices.
You guys need a Sticky on the forum with known wheels that fit.

I'm awaiting replacement front wheels from HRE but should have mine on this Friday (stock suspension for now).
FR 19x8.5 +47
255/35/19 (should fit)
245/35/19 (if the 255 doesn't fit)
RR 19x9.5 +45
285/30/19 (does fit and does not rub, test drove the car)
Previously 19x9.0 +4? (?? don't recall, will have to check them) These did not clear the upper control arm. The tire was not touching the control arm, nor was it near it, it was all wheel, with that I expect my 255/35/19 will fit but I have 245/35/19's in case they do not.
Replacement wheels arrive Friday, so I should know more then.

You might want to call them and double check before you guys spend money on shipping back and forth.
Just my 02!

Thanks Jim,
They're already in the mail - We shall see come Friday. This has been a long back and forth to get to this point, I sure hope they're right with these offsets.
Guess we'll find out for sure in a couple of days....

I just don't see how the math can work? I was told even the 20x8.5 which is taller also does not work. The thought was that maybe the 20 would fit since it would be taller on the inside and have clearance at the curve of the control arm, but it was later confirmed that it does not. Sorry you are having such a hassle with this, but I really think the car is going to require a 8.0 with a ET+35, and the 8.0 should allow the proper 225 tire to sit square on the rim, and you can run the factory 225/255 combo and avoid any risk or issue with the 4matic function. Just a suggestion. Let us know it works out.

Hey Jim,
I called HRE - they say their engineers measured and confirmed, the missing piece (good thing I called) is a 3mm spacer is required to guarantee caliper clearance. That got lost between HRE and my retailer, now trying to track down a spacer to get here by Friday morning.

Attached are some photos of our C class sport, the application on the car is 19x8.5 ET45 Front with 225/40-19 OE tires, and 19x9.5 ET50 rear with 255/35-19 OE tires. The 8.5 and 9.5 as you can see position the wheels out to the fender edge, the wider wheels allow the tires roll a bit on the shoulders keeping the tires somewhat in the fender well. As you can see the tires and rims come out of the fenders where the body rolls to the lower portion of the car and the top sits just inside the top of the fender wells.
The C63 models have a wider front fender compared to the rest of the C class models, so the applications that are listed for the AMG 63 model are going to have a lower offset for the front wheels, but the fender allow that more aggressive offset, where the rest of the models do not have the room.
The C450 has similar suspension as the 63, but does not share the body parts for the offset clearance.
If you are planning to run aftermarket wheels on a C450, because it is a 4matic I would suggest sticking with the OE recommended tires for the OD and run a 19x8.0 and 19x9.0, this will give the clearance and offsets needed for the suspension and brakes, as well keep the fitment for the tires to sit square on the rims and fill out the fender wells.
There are really no cast wheel manufacturers making this size because most wheel companies are trying to fit a variety of MB and Audi applications, so some fitments look more aggressive on some cars, and some look conservative, but this allows suppliers to fit a broad range.
Unfortunately for the C450, this is an application that sort of stands alone, so those of you with the 450 most likely will have to spend the money for a Forged wheel option. It will be more money for sure, but having to run universal spacers will not be necessary, which I would honestly opt that route.
Hope this helps!

So according to HRE engineers an 8.5 with a +44 should fit. Hmmm, that's awful close to 8.5 with a +45 which people have reported is nowhere near fitting. Somebody's obviously wrong in this scenario. Can't wait to find out who.

Ahh, got you. I called my wheel guy while I was seriously considering a 450 and he assured me there were all sorts of options, but I guarantee they were all from vendors who had grouped the C450 into the C300 for fitment and hadn't yet figured it out.

I would be really surprised if they did not know that the C450 has a larger control arm than the other models, but it very well may be the case...they just might not know.
The other issue is running a universal spacer...I would honestly opt for spacing the factory AMG wheels with Hub Centric spacers, when I changed my car back to stock I installed the 12mm on the 7.5x19 front and 15mm on the rear 8.5x19...with matched lug bolts. I posted a video today on Instagram at 80mph on the freeway showing the car has no vibration, again with Hub Centric spacers in and out to spec there should be no issues, but universal spacers will definitely be a risk.

On my HRE FlowForm spec sheet it clearly notes that for W205 C450 models a 3mm front spacer for brake clearance is required. Dealers should be aware of this during a sale for this model vehicle.

Well, that's a head scratcher. Previously in this thread I commented that Mandrus listed C450 specific applications. Those were 8.5" with 45 offsets for the front. When I checked their fitment guide again today, nothing comes up. So they've changed their minds. However, HRE seems pretty confident that their 8.5" with a spaced offset of 44mm fits fine.
Dave, when you say the fit is "aggressive" do you mean close to the fender side, or close to caliper side? It could be that some shops are gun shy when it comes to caliper clearance.

Everyone always freaks out about spacers, but if you can mount the wheels to the hub with the center of the wheel, then you should be fine. Also hub-centric spacers with properly matched lug bolts should pose no risk or issues. The Big name tuners have all used the spacer/adapter concept for years and there has never been a issue, so when people get all freaked out about spacers, remember that Brabus holds the world record with the CLS Rocket at 237mph with Brabus wheels that have spacers/Adapters.
These spacers and hardware kits are essential to allowing the wheels to properly fit each platform with the most aggressive and functional application.
I would assume that HRE as reputable as they are have tested and approved this application, so I am sure the outcome will be a success.
