My 2008 S-65 has the heavy 390MM rotors... Also cheesy two piston sliding calipers. Rotors are dead-dead-deadski. No dimples to be seen.

For or fun I ordered up a pair of Brembo 390MM rotors on hats for a 220 Chassis S-65. They bolt right onto the hub. Like the hats. Marginally less weight for a lot less money then 221 rotors.

Who among us is aware of if front brake calipers for a 220 bolt up in a 221? Brake hoses will have to be changed too.

The pair of caliper pistons in the 221 car are 42mm. Don't know about piston sizes for the 220 car.

Thoughts? There is a 220 S-65 being parted locally which makes much of this $ting less.

Brabus K-8 may morph into EV12. Have to be sure the engine survived.

Man oh Man after reading that I am guessing you are an engineer!
Last year I changed my rotors with OEM MB rotors I got on line and Red Stuff pads. For what the car is I didn't think the costs were "that bad" all and all. The Red Stuff pads work perfect with no dust!
Good luck with you're project, you are certainly more adventurous than I am.

Ouch! Low blow!

I'm a guy who sees a problem (heavy solid expensive rotors, cheesy heavy sliding calipers for my car) (Not enough cylinders or turbos for Jay's Brabus K8) and looks for a reasonable solution.... Cuz making an EV-12 and 'reasonable' belong in the same context! Lol

For reasons unbeknownst to me our friends at MB saved very little money per vehicle to fit crap calipers/rotors to their range-topper vehicle. All that extra unsprung weight ��

Note that 220 S-65 and 222 S-65 both got better parts. We'll see if the caliper piston sizes work and if they will bolt up with minimal drama.

I'm hoping that I'm not the only guy on the planet (again) who is looking to do such a thing without laying out mid-high four figures.

The local crashed S-65 will be the donor if parts fit. Texting + driving + tree bad mmmmm-kay! Bummer as it was a nice car.

Not all meant to be a "low blow"
Good luck and hope it works.

Seems I need to do better with the 'smileys' when making tongue in cheek comments.

No offense taken. Cheers!

This is how the brakes got fixed.

A kit of Brembo six piston calipers, 405mm rotors on hats. Bracket to mount the radial mount caliper. Brake line.

Offered by The Tire Rack.

Utterly straight forward replacement for more brakes.

Looks great.

Looks great 👍🏾

I've had opportunity to bed them right and give them a proper thrash.

Those who have experienced brakes that go away on a spirited drive... You know who you are!

Give your car a kit like this. Improved brake pedal feel.... Brakes always there and able to make ABS work from any speed every time.

Money well spent!

The Tire Rack offers these kits. The 415mm rotor will fit under the stock 20" wheel on my 221 S-65. I got 405mm rotors.

Brakes that work every time pay for themselves when the car does not get wadded up.

replaced pads and rotors all around dimpled vented discs and ceramic pads. Cost me 250.00 plus two cans of brake clean. Stops on a dime no fade no noise. The weight difference from Oem to my zinc plated is 7lbs per side. I have two single piston calipers per side in front upper and lower. Rears are are single piston. While there I changed both A-arms and ball joints. For 150 bucks.

How did you do that? My 2011 S63 still has very expensive rotors!
Sources?

Couldn’t be any easier

Mercedes engineers know what they doing most times. I found it’s not needed. My S65 S63 and SL63 all stop on a dime. Buy it sure looks nice. I could use a set of the same wheels!!

What brands did you go with? My 2007 S65 rotors are $800 each from most places.

cams63benz

R1 concepts will hook u up!!

Anyone looking to sell the chrome wheels please hit me up?

Thanks! I checked and they do not have the 390mm rotors on my 2007 S65. I'll keep checking in.

Stock brakes on a 221 S-65 are well used with one afternoon of spirited driving.

Don't drive that hard? Leave them stock.

I drive my car. The brakes get used. Money well spent for brakes that are not warped and making angry noises after a day of fun!

We'll see how long rotors and pads last. I'll update with how it goes.

JohnLane

Here's an update....

Now that she has front brakes that inspire confidence.... They get used.

Thus: Front tires will go away more quickly. Rear rotors are letting me know what they think of it by shaking on application.

JohnLane

Update....

I gave gave her stock rear rotors and sporting brake pads. No more shakeys in the rear.

The Brembo kit in the front of the car continues to be excellent. Used up a set of tires on a couple of spirited drives. Brakes get used and have not faded yet.

i did the opposite thats explained in this thread

i have a 2002 w215 cl500 chassis and found the 221/216 amg brakes are a direct fit for the front. just need to drill out the steering knuckle a bit for the larger mounting bolts, much like the typical process of upgrading from 220 to 220 amg calipers

i'm coming from a 330mm front rotor to a big 390mm rotor. the 221/216 calipers and rotors are absolutely heavier, but if you compare stopping distances of amg 220 vs amg 221, you'll see that even though the car is heavier, the stopping distance is similar. so this tells me the 221/216 brakes are possibly even more powerful

i spent $280 on used OEM front rotors and $300 on front 221/216 amg calipers. i can't think of a cheaper big brake upgrade for the 220/215 chassis

Do the 220 S65 and S55 wear the same brakes front and rear?
