I am extremely confused. I have tried H&R, ECS Tuning and Supreme Power spacers now - all of them don't fit. The only luck I have had was with a slim spacer (less than 10mm) without hub centricity.

- The ECS Tuning spacers had the incorrect chamfer on the front of the spacer resulting in the spacer not sitting flush with the rear of the wheel hub. (10mm)

- The H&R spacers had the same problem as the ECS Tuning spacers. (12mm)

- And the Supreme Power spacers (which others are running on the C63) do not seat to the OE hub because the inner bore of the spacer steps down too soon. (12mm)

The last thing I am willing to try are the burger motorsports spacers.

I know some people have bought ebay spacers or paid way too much money for custom spacers for the car - but I will not entertain either of those options.

Just some info for those c43 guys (and I would think it would also apply to the c63 guys). Now, if I were to run the 15mm spacers from supreme power, I am thinking they would work.

Try 42 Draft Designs. I think I remember Vic saying that he couldn't do anything less than 15mm for that reason.

Yep, I had stated that the Supreme ones will work but because of the snout length on the hub you need to go with 15mm to allow for the factory hub to sit hubcentrically (a word?). 12mm is too short unless you find a unique spacer that allows for the hub to mate in and still not hit the rim backing.

Thanks fellas.

I used 15mm ECS spacers front and back on my coupe with no problems.

I also had ecs spacers 20mm and 15mm that fit perfectly.

I'm using H&R 15mm no issues.

After consulting with both burger motorsports and surpreme power, 15mm spacers seem to be the minimum viable spacer when not using the original hub to mount the wheel.

So, I would say 3-8mm spacers work.

and 15mm+ spacers work.

But nothing in between. (only applies to buying spacers off the shelf.)

Only problem with 15mm, if you've used a wider tire, they won't work....

15mm is already too much on the c450/c43 IMO. Looks too mexi-flush, especially without lowering the car.

A lowered car with a bit of natural camber, 15mm would work. But, I'm not planning on lowering the car as of now.

As you've already mentioned 15mm+ spacers are needed following my experience with narrower ones last year, here's a pic I drew awhile back to illustrate the problem:



The aborted attempt to fit 12mm spacers!:

Anyone got a link for purchase of 15mm spacers? Also will 15mm on front and back pull the wheels out flush or do you need different sizes for front and rear?

Guilty

This is what I have on my car. They work 100%.

Vassago

what wheel bolts did you use? I'm assuming that the stock ones will not work.

Guilty

I bought extended lug nuts from Supreme. Not sure about the spec. Give them a call

Vassago

I'm surprised no one makes a 15mm spacer kit with bolts for the 2017 C63s. It would be so much easier for purchase.

Supreme Power will sell you a kit. Talk to Brian.

Vassago

Thank you, just sent an email to Supreme Power.

DVision44

These ECS spacers work fine and come with bolts

Why won't they work.

auditoamg

You'll rub.... Especially if car is lowered.

Guilty

Why are you on probation bro? Who did you **** off

JPMBenz

So if you run a 295 on the back; you can't run spacers at all? I feel like people are running 15MM with 295's...

auditoamg

I wouldn't do it.... Several folks have advised against.

Sanch

Incorrect audioamg.

I had my car lowered with 295s with 10mm spacers in the rear. It fit perfectly and there was no rubbing whatsoever. That's how the car should have come standard. You can even do 12mm and pull it off with out rubbing.

I'm not sure who advised against it but I can bet they are people who haven't even tried it. I can personally say no issues.

Please see my car when it was lowered with 295s - 10mm spacer rears and 20mm fronts.
