Just got 85lbs worth of rotors in the mail! I decided to skip the OEM AMG rotors and after some recommendations, ended up giving these a shot. They are much larger than stock (355mm) and are slotted/vented front and rear, which looks much better than stock.
I have EBC Greenstuff pads front and rear that will be paired to these new rotors. Side note, used Redstuff in the past and liked it but, way to short of a lifespan and I don't auto-x my car and don't really need the red. Had better luck with the Green....
I'll let everyone know my thoughts on these rotors after I put some miles on them. Full set of front and rear rotors was around $600. Now I just need a better set of 4 piston AMG in the rear.

So you have larger diameter rotors but stock caliphers.
I understand having high performance brake pads, but, how does larger diameter rotors with same brake pad contact surface improve braking?

Larger rotor + larger caliphers and matching size brake pads = better performance?

Like the rotors - shinnny. Are you using 4 pot on the front and 4 pot on the rear. Not really sure if that's the way to go. Thought we had to go 70 -30 braking principle to balance the brakes (or something like that) i.e. 6 pot on front and 4 on rear. Sure some one will correct me if i am wrong.

Right now it's 4/2 but I want to go 6/4. More for looks than practical reasons.

Dunno, ordered the "matched" pads with the calipers (it all came together) so I would assume they're made to work together. I don't run auto-x so I don't really care if they are "better performance" in that regard. Better braking is always a plus but mainly it looks a lot better than stock!

Most companies that sell "big brake kits" don't sell matched pads with them and if someone was to order new pads, they would have to order them based on the vehicle they own. With that in mind, I'm not sure the pads need to be bigger just to get better performance from a bigger rotor. Otherwise how the heck would you order new pads if not based on the vehicle??

Just want to help. The 6 pot caliper i have (CLK 63 front) has rotor size 360, and you have 355 (isn't the C55 stock rotor 345?). Have you a 6 pot caliper in mind to fit the 355 rotor?

[QUOTE=tudu;3375914]There were 3 different sizes available, stock (345) then the next one up (355 or 360 don't remember exactly) and then the moster 380 that required 19" rims. Those are all front dimensions of course. The 63 caliper will work with this setup...so I was told at least by people that know much more about brakes than I....

[QUOTE=SilverBulletAMG;3375926]If they had a 360 rotor i might have gone for that depending on the diameter of the disc as well, as that size might have fitted the CLK 63 caliper. Hope it all works out. There are as you say many forum members who know more about brakes than either of us do. Let us know how you get on.

When I did my 6/4 converstion, I recalled that there are two type of rotors for the AMG 6 piston front. The earlier 2005 SLK55/CLK55 used a one piece 355 rotor for the front. The later SLK55-030/CLK63 package came with a two piece 360 rotor. Here is a pic of the ealier non 030 package rotor.

Didn't know that a 355mm rotor would fit the stock brake system up front; do you need an adjustment bracket for the caliper to be properly aligned?

Took it to the shop and said, "git 'er done". They're on and it works...lol

brakes working is definitely a good thing! LOL.

I'd suggest you watch your rotor wear - if you have a sizeable outer "ridge" forming after awhile of use, you'll know the pad contact alignment isn't optimally positioned on the rotor surface. Similarly, the inside edge of the pad might not wear, which would suggest the same thing.

Keep us posted!

Thanks for the heads up. I'll definitely be keeping an eye on that.
