In stock. Ready to ship.

Designed as a direct brake rotor replacement for the OE 390mm 2-piece front brake rotors (no modifications are necessary), and work with the factory AMG brake calipers. The Evosport rotors offer a significant improvement in cooling and brake performance over factory brake rotors- over 50% more air for improved cooling and reduced brake fade on street or track. In addition, not only will the upgraded "floating" rotor design help mitigate brake fade, but they are lighter than stock and reduce unsprung weight on the front axle. This means better acceleration, braking and cornering.

To minimize casting requirements, the stock OE rotors are designed to be used on either Left or Right side (single part number) utilizing an inferior pillard vent design. This does not allow for the most efficient flow of air. The Evosport rotors have a specific Left and Right application to allow correct and proper venting and the most efficient channeling of air.

The Evosport rotors provide a much great ROI and lower cost of ownership by allowing you to replace just the outer ring of your rotor during brake replacement (few hundred dollars). The stock OE rotors require you purchase the entire rotor assembly, and often times they can only be purchased in pairs (several thousands of dollars).

The hats on the Evosport rotors are made of lightweight aircraft-grade aluminum. Engineered directional vents on each hat dramatically optimizes cooling and further improves airflow.

Drive pin washers made of strong Inconel (used in military, aircraft engines and racing applications) are practically impervious to oxidation or corrosion. Curved design on the drive pin washer add additional tension to the assembly thus reducing rattle.

Each rotor is silver zinc coated for anti-corrosion, mitigating surface rust on the vents and rotor. Zinc coating also benefits customers who live in colder climates where snow and road salt is encountered.

Rotors are 100% made in the USA.

What's the front rotor size of a regular SL55?

 

360mm/14.2". We have these available already.

We will offer an upgrade kit soon that will allow an SL55 to use our new 390mm rotor.

 

We just ordered rotors for my SL55 from you and they should be arriving in NY any day now. Which rotors will I be getting, I assume the regular 360mm with the gray hats? Other than the size and color of the hat is there any difference?

 

360mm. All our hats are now black anodized.

 

I will like the black. An unexpected surprise! Can't wait to feel the difference.

 

Awesome!!

Can't wait to see these installed and feel the difference in braking!

 

Why woudn't they fit a SL600 ?

 

Some of the SL600's came with the 360 rotor, not 390 so this would not bolt on. But once we release our adapter kits, you should be able to install the 390 on SL600's with the stock 360.

 

Any update?

 

The 390mm upgrade is now available for E/CLS/SL55's with the factory 360mm front rotor. We will post something official shortly as well as update our website.

In the interim, here are pics of our new 390mm on a CLS 55:

 

That's awesome it fits into 19"

 

WOW. I need a set.

 

It will fit into most 19" wheels. Some 19" wheels with very aggressive steps and small barrels may post a challenge. If it's a 19" factory wheel, it will usually always fit.

We just installed a set on another CLS 55 running the factory 19" CLK63 Black Series wheels and fit was perfect. Will post photos if anyone is interested.

 

Have you guys tested these rotors (or your lightweight 360mm for that matter) on a road course? I'm a bit worried that the wider vent in the friction surface (and therefore reduced thermal mass) would cause temperatures to get hotter and may contribute to premature brake fade.

Also how much does a pair of replacement outer rings cost?

 

Price ?

 

What do you mean by "vent in the friction surface"? Yes they have been tested. Far superior to stock OE rotors with respect to brake fade.

Outer rings are $369-$399.

$2,100 for 390mm front set including the adapters and hardware.

 

This is what I mean:

I assume this wider vent is where the majority of the weigh savings comes from. I'm curious if the increased air flow makes up for the decreased mass in terms of ability to dissipate heat.

each?

 

Wow, much thinner plates.
How would that affect cracking?

 

I looks like over the edge bought some. Maybe he can report some findings.

 

Hmm, don't SL65 have different piston diameters vs the stock 55/600 cars?

In other words, using the same caliper and up-sizing the rotor would throw off the brake balance quite a bit.

 

so this is going to sound like a noob question but im sure within the next year I will be replacing all 4 of my rotors. So if I dont track my car, just for everyday driving is it necessary or what is the advantage of getting a set of these rotors for around $2k if I can get a set of mb oem rotors for less than half that?

 

Lotsa expensive stuff can go south.

 

You are looking at our evo1 rotor. Our new evo2 360mm has almost double the amount of vents. Also, keep in mind our rotors have directional vents. The OE rotor is NOT directional, they are pillard.



Yes.

The thicknesses we are dealing with do not affect cracking. And again, the picture is our evo1 rotor design. Our new evo2 360mm rotor have wider plates.

 

The benefits can be realized for everyday driving and certainly not only for cars that get tracked. In addition to better long term return since you only need to replace the outer ring next time, plus better heat dissipation means it's easier on your brake components and less degradation over time.
