CLK55 / SLK55 Group Buy - EVO Rotors

I spoke to Evosport today and asked them about a possible group buy for their super-light weight rotors. Currently they're only available on the E/CLS/S/CL 55's.

I'd like to see how many of you would be interested. This would help a LOT in performance both straight line and cornering. Here is Evo's write up:

Designed as a direct brake disc replacement, the AMG brake discs on all four corners (No modifications are necessary. The disc will bolt directly to the car and work with OE AMG brake calipers). Not only will the upgraded multi-piece "floating" discs help mitigate brake fade, but are lighter than stock and reduce unsprung weight by a total of 34lbs. on all four corners! This means better acceleration, braking and cornering. In addition, you get to maintain the AMG calipers without going to a more expensive solution that requires replacing them. Available drilled or slotted or slotted.





If anyone is interested, please PM me or just reply.

I hope a few of you are as excited as I am, lets try and make this happen!

Thanks!

P.S. Estimate in Price: About $2000/set & 10 buyers. Could be less!

Also from Evosport:
Not only will the upgraded disc help mitigate brake fade, but reduce unsprung weight by as much as 15lb. per corner up front! And you get to keep the OE look of the calipers w/o going to a more expensive solution that requires replacing them. These discs are more inline with what you find on the 65 AMG cars.

The central “hat” section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is made from cast iron, constructed in the USA and is made to the same specification and material as used by professional racing organizations. It is a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

The rotor and hat have a floating mount system, which utilizes high strength alloy steel drive pins and are cadmium plated for long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by grade 12 cap screws with hardened washers.

One more important thing worth mentioning here...the stock discs do NOT have a unique right and left part. This means there will be one side (the right side) where the vanes of the disc are backwards hence working against optimal brake venting. The new discs offer a left and right so that the vanes are pointing the correct direction for venting.

Although its doubtful cracking would manifest itself for daily driving, its something to consider - cracked rotors mean replacement.

The Evo rotors look cool & due help unsprung weight, but I don't think you are going to notice on the street? In any case, $2k is a good price & it does reduce unsprung weight. I'm just not sure of the durability (its likely just fine for street use). Just something for you to consider (little to no noticable differnce in performance vs. trade off for possible cracked rotors). See ya.

R1,

Appreciate the post. Again, I'm just a nut for what I hear. These rotors will probably never happen since not enough people are interested. None to say the least.

Thanks

Since I'm not planning to track my car, I'd buy them (these rotors should be fine for even hard street driving). I just have to wait, I've been throwing too much money at our SLK lately . If it helps, I'll go in & buy them maybe later this Winter or early Spring?

See ya Dinko!!

Same here, you really put my hopes down earlier. Besides, I don't think they'll crack. I hope they will have them soon, lets just be sure to purchase them together. I know that Rob (RBSLK55) mentioned he'd be interested as well.

Great point. Just to give you a point of reference. I had these same rotors on my 540 for 4 years and over 50,000 miles. And this was the 14" version (smaller). They are still going and I would guess at least another 30,000 miles min.

That car is almost as heavy, so that should give you some peace of mind that they will last.

Thanks
Brad

There ya go. Thanks for the post. For daily street use, even "rough" street use, the EVO rotors should be fine then. Its good data - thanks Brad! I'll make sure at least Dinko & I buy them together and who knows, maybe some others will jump on board by Spring .

Rotors are in stock for $1,999 a set (front & rear) and available for E55, CLS55 and SL55, CLK63 Black Series (rear rotor only). For a limited time (now through end of Feb.), will include stainless steel brake lines at no additional cost.

The rotors are now drilled & slotted (see pics below)...

Does anyone know if the CLK63 BS uses the same rear rotors as a regular CLK63 or the SLK55 P030 package brakes?

I have just checked it and they are exactly the same in the rear. (Fronts are different).

Here is the rear part number for CLK63, SLK55, CLK63 BS, SLK55-030.

Rear Left Caliper: A0034202983
Rear Right Caliper: A0034203083
Rear 1pc rotor: A1714230212

So the Evosport rear rotors should fit all SLK-AMG and all CLK-AMG considering the fact that they fit stock rear Black Series. The problem is that they are side specific so to match front AMG that they are the same on each side you will have to take 2 of one side.

Notice that the CLK63BS rears are not the same as the E55 SL55 CLS55 etc...

============================


If anyone needs info on the fronts:

Front CLK63 & SLK55-030:
Front Left Caliper: A0034206783
Front Right Caliper: A0034206883
Front 2pc rotor: A2094210112

Front CLK BS:
Front Left Caliper: A0044201583
Front Right Caliper: A0044201683
Front 2pc rotor: A2194210212

Just to clarify... should everything highlighted in red should read 'front'?

What am I missing here? I realize MB uses the same rotor left and right, resulting in the slots/vents going the wrong way on one side. That is partially what this ES rotor upgrade would resolve. So, size aside, what's the problem?

On the stock, in the left side rotors the holes points forward and on the right side rotors the holes backward.

If you put side specific evosport rotors, on one side it will be matching with the front but on the other side, the front rotor holes will point forward and the rear rotor holes will point backward which will look at least strange.

If we keep front, we should buy only 2 rotors identical and each 2 from the same side, so it match the front pattern.

Okay, I didn't realize you were considering keeping the front stock while replacing the rear only. If done so, one side wouldn't match and may look a bit strange.

For me, I'm waiting to see a whole ES set; preferably one that would match the 030 size yet still provide weight reduction and the benefit of the vents pointing forward. Since front rotors get worn down first, I can't imagine myself buying just a rear set... even with the weight savings.

I'm also interested on the complete setup (Front030/CLK + Rear) but right now in the best case there is only available the rears.

Don't know if evosport is planning to do them in short future.

FYI...

EVO.BRK.M09.R01

Rear multi-piece lightweight rotors from evosport replaces heavier factory one-piece solid rear rotors and matches factory multi-piece fronts. Drilled and slotted (13.0"/330mm). Direct replacement for factory rear rotors; no modification necessary. For use with OE AMG brake calipers only. Brake pad replacement recommended during this install.

Application: W209 CLK63 AMG Coupe/Cabrio, CLK63 Black Series; R171 SLK55 AMG
Price: TBD
Release Date: April, 2008


Someone PM'd me if they will work on the C55. The answer is no. The rear rotor p/n for the C55 is 2104230812 and it's an 11.8" disc.
