Alright guys so it's time to replace my rotors and pads and had a couple of brake setups i was contemplating. My C63 is a daily driver which gets some spirited driving () At this point i'm debating if should upgrade to 2 piece rotors front and rear or just stick with the fronts. Would upgrading to 2 piece even be worth it for me?

OEM 1 piece rotors, pads (front and rear): $939.00
OEM (P30) 2 piece rotors (front only), pad (front and rear): $2163.00
RB Brakes 2 piece front rotors, pads + oem 1 piece rear rotors, pads: $1943.00

I'd say either keep them 1 piece stock with something like the Porterfield pads or if your really want to go 2 piece, go with something aftermarket. Vendors on here will help you out. I have no experience with any of the 2 piece rotors so I won't send you any particular direction. But aftermarket will be lighter, probably cheaper, and offer more options. And IIRC, the P30/31 2 piece rotors can't simply replace the braking surface but aftermarket units often can (ie-you keep the aluminum hat)

I didn't know there were OEM rear two piece rotors.

itzjonjon69

oops sorry i meant front and rear pads! OEM 2 piece is only available in the front

Ingenieur

The $939 is a good price
Where did you find it?

I'd stick with the 1 piece unless you track the car

itzjonjon69

www.oediscountparts.com free shipping too! i ordered my ROW airbox covers from them.

Ingenieur

Thanks
Book marked for future reference lol

+1. unless you're into the coolness factor, one piece is fine for the street. heck, I am even considering using one piece oem's to replace my p30 rotors when the time comes.

abcut973

Yeah if you do not plan to track the car OEM 1 pc are just fine for daily driving and some spirited moments.

Ingenieur

A $1200 difference for marginal track advantage and no street advantage
For the difference if you replace the 2 piece every 80k miles you do the 1 piece every 40k and still be way ahead

Before I get the 'cheap *******' BS I can afford it but don't squander my hard earned cash

m a x i m u s

cheap *******! jk. I'm on the same page as you.

itzjonjon69

Alrigh guys so i think i'm gonna stick with the OEM 1 piece rotors. Now what brake pads do you guys recommend?

Also... I was on ECS tuning and i noticed they said that rotor screws aren't included. Do these need to be replaced or something or can i reuse the ones i have now?

Ingenieur

I prefer 'frugal *******'


Heck $1200 is a set of good tires

Ingenieur

I'd stick with oem
A bit dusty but easy on the rotors and good cold bite
They are smooth in application and transition nicely
Get the srews you 'cheap *******' jk lol
You will probably bung them up getting them out
Use a bit of anti-sieze on the new ones

itzjonjon69

lol damn... anyone know how many bolts i need?

abcut973

One on each corner.
As for brake pads OEM are fine but endless ME20 pads are not too bad and less dusty.

itzjonjon69

I'm looking at a picture and it looks like each rotor requires 5 screws, so 20 screws in total? i was thinking of going with the Porterfield R4S pads...

abcut973

Which screws are you talking about? I only see one?



Porterfields are a good choice as well.

abcut973

The 5 holes you see are for your lug bolts.

itzjonjon69

oooh ok! i thought those 5 holes were for the rotor screw!

itzjonjon69

What do you guys think about Centric rotors? Don't they make all the stuff or stoptech?

m a x i m u s

no opinion on centric, but I was told brembo made the p30 rotors.

m a x i m u s

and you can probably reuse the set screws.

Ingenieur

I never had much luck with them
Much swearing and cursing involved when they strip

If you do
Let sit with some penetrating oil squirted on them
Insert key and tap lightly to break loose
Then make sure the tool is seated fully and apply gradual pressure

Then throw a fit when it strips lol
E-Z out tools should be on hand
Or drill the head off and remove the shank with vice-grips
Either way you'll still need a screw

You can, as it has no set tension on it because the lug bolts carry all of it. They should be buttery loose when you go to remove them.

I do brakes on BMW's all the time (exact same single set screw) and it comes out with a tiny bit of force on a 3/8th wrench. Actually did the brakes and discs on a Range Rover sport (exact same brakes and very similar rotors), and it was also easy.

But throw some copper anti-seize on them when they go back in.

The head might be a bit corroded, so when you insert the hex bit, give it a smack with the ratchet to make sure it's seated.
