would like some advice/opinions

i've got a 2010 c63 with none of the performance options from the factory. only have lsd. so i guess this means i have the 1pc rotors right? and i've read some threads saying the replacement rotors are inexpensive...

it's a daily driver and i don't track the car except the occasional visits to the drag strip.

right now i need to replace my stock pads. i don't even know how to check the rotors.

the replacements i have but not installed yet are endless me20 for the fronts and mx72 pads for the rear. should i just stick to oem pads? i also have rear evosport rotors. i've had these parts for a while and been wondering if i should use them or sell them and just keep it factory.

i've been told with these endless pads and daily driving, i shouldn't have to replace my pads for a long time.

if i do plan to keep them and install them, should i wait to purchase upgraded front rotors? also, should i also upgrade brake lines and brake fluid?

or are these upgrades overkill for my uses?

i know it's a whole lot of questions.

Overkill. If the car is a daily, keep it simple.
360/330mm rotors and brembo brakes are more than enough for a DD.

bluejae

are there potential weight savings?

I need a new set of brake pads not because they're worn out, but because of how much brake dust the OEM ones produce. I've heard the endless ones produce very little dust, which keeps your wheels cleaner for longer.

bluejae

hmmm... so then maybe keep the pads and sell the rear evosport rotors i have...

is 360/330mm an upgrade? any examples?

olszowa12

360mm front and 330mm rear are stock disc sizes.

bluejae, are you in Toronto ?

How many miles do you have on your car? I just broke 20k recently and am wondering if I will need new pads soon or not.

bluejae

oh... ok... will the pads i have work on the stock set up?

nope, texas

a little over 48k

Upgrading your brakes will only lead to better performance on hard, high speed, repeated stops. Your stock brakes are more than enough to lock up the tires, you could have the biggest, best brakes in the world and it wouldn't affect your initial 60-0 distance.

Not true. Upgrading to lighter rotors would lighten unsprung weight. Evosport rotors, for example, is claimed to be 40lbs off stock one pieces. If you go along with the rough estimate of 4 x unsprung weight = sprung weight that's 160lbs off, almost the weight of an adult passenger. That basically translate to not just better braking but accelerating and handling.

bluejae

wow... with that much weight savings... maybe i should consider keeping the rotors... judging by this thread here https://mbworld.org/forums/c63-amg-w...-2010-c63.html

the difference in weight on the front rotors are about 12 lbs since i have the 1 piece.

but then i'm back to whether it's overkill... i don't understand the unsprung weight stuff but 160 lbs is a lot...

HoozyerdaddyC63

You might want to do some more research. You are not going to save 160 lbs.

You'll save "up to 40-lbs unsprung weight savings over stock! 26-lbs weight savings on vehicles equipped with 2-piece OE front rotors." That's on all four corners.

Overkill. Use the pads you have already purchased. If you can find someone to buy the rear rotors, you have a lot more gas money.

The minimum thickness is printed on the edge of the rotors. My fronts went 90k and the rears are still on at 107k.

I upgraded my front rotors only because it was cheaper than OEM.

See my DIY in the W211 section.

To answer the OP's original question, the OEM setup is ridiculously good, and you should not have any problems. The Evosport rotors are very good too. They are lighter so they obviously have less material in them - they will not last as long as the OEM. Just remember that and keep an eye on them. They should still last at least as long as a set of pads.

Beyond pads and rotors, the OEM lines should give you no problems. The OEM brake fluid is excellent and I have tracked my car with the OEM fluid with no problems. You should change the fluid every 2 years (IMO) as preventive maintenance, though.

I did install stainless brake lines on my car, more for brake feel than anything, but I use stock everything else (I have a set of Evosport slotted rotors in the garage that I have not installed yet).

bluejae

does the c63 have a sensor that tells you that you need to replace the pads? or do you just have to eyeball it?

Mort

There are sensor contacts on the passenger side front and rear to indicate pad wear.

bluejae

does it tell you on the dash when you need to replace? or are you supposed to look at the sensor contacts?

abcut973

I think you get a message on the dash.

Mort

Yes, you get a message in the multifunction display "Check Brake Pad Wear". You should also check thickness at each scheduled service.

Greetings!

Honestly the Endless ME20's would be too much for daily street driving and they may squeal a bit too much for your daily liking... I believe you purchased the pads from us, so if you are serious about installing the endless pads please let me know and we can exchange them for the MX72's in the front to match the rears. Another option is to use the porterfield R4-S pads as these are also great pads that you can use on your daily driven C63 and are much more affordable then the endless pads. We also have the 2pc front rotors if you would like to have them match your rears.

Please always feel free to give us a call if any of your questions or concerns.

You might want to re-read what I wrote and do some research of your own. I already mentioned a total of 40lbs for all four corners. Wheels (or any parts of them) are rotational mass however and that equates to about 4 to 1 ratio against non-rotational weight (although some claims to be as high as 10 to 1, which I find to be too incredulous). Although I did erroneous misuse the term unsprung weight where as rotational weight is more appropriate to the context. In the end, if you were to believe the rotational weight ratio (as I stated in my original post), then replacing all 4 rotors and saving 40lbs off of rotational weight is equivalent of 160lbs sprung weight off.

gthal

Overkill IMO. The stock brakes are fine even with light track use. Yes, there might be a weight savings but, again, for normal daily driving it is not particularly relevant or worth the expense IMO.

bluejae

since ive already got pads and rear rotors and the amount of weight savings i may keep them...

how do i know if my oem rotors are going bad?

since i only have replacement rear rotors, would it be a problem to replace tge rear rotors and keep the front oem rotors and put the endless pads on the front... or are they not compatible?

The lighter brakes are like putting lighter wheels on the car they will change the dynamic of braking and acceleration maybe not so much that you'll feel it.. I changed mine at 28,000 miles stock rotors are like brand new... Mine where a good deal for 1,600 but sold them already
