E39 Brakes & rotors

Hello:

I'm planning on changing out my brake pads and rotors on my 03 E39 530 (Sport) (about 130k kms). I've preliminarily decided to go with these pads:
Akebona EURO Ultra Premium Ceramic Brake Pads - Front (4-Pad Set)
Part No. EUR681

I'll also pick up the ECS coated rotors (these are the front, I'm looking at the similar for the rears..
http://www.ecstuning.com/BMW-E39-530...ors/ES2135689/


Would these be good choices? Would there be anything else that I should change out while I'm doing it ?? (I won't be doing it personally). I'd like to paint the calipers as well.

Any advice greatly appreciated.

Thanks

There are lots of opinions on brakes.
Ceramic pads generally have less dust and less initial bite/stopping power. Some people claim that the initial bite/stopping power is dramatically reduced with ceramic...so much so that they feel it to be unsafe. I guess that is subjective and would depend on what set-up you are using. I recently installed PBR deluxe pads (mild ceramic) and did notice slightly less bite but I am happy with the performance. I paired them with Zimmerman rotors. We'll see what the dusting is like in the summer.
Check out autopartsway.ca they have a few options for brakes and prices are reasonable.

Is there a significant savings over OEM stuff? I had WBR... World Brake Resource pads on the M5 and they were fine ... till I took it to the track. They died in just one day... about 60 km. Towards the end of the day, I noticed that there was about 1/8" thick film of brake dust on the front wheels but what really caught my attention was the warning ... low brake fluid.

OEM pads have survived 3 track days with no sign of excessive wear.

I have OEM now and they are "dirty", lots of dust. The Akebona, from what I've read on numerous sites, are a lot cleaner, if having a bit less bite.

I am a firm believer that the OEM M5 brakes are more than adequate for a stock performance car. I've done many laps on stock brake set up without ANY issues.
They do dust, but they are great.
I recently installed slotted rear rotors along with HAWK HP+ Aggressive brake pads. The squeal is unbearable. I am planning on putting OEM pads back on and running just slotted front and back with OEM pads.
The braking will be slightly improved over stock due to the better heat dissipation of the slotted rotors, with the comfortable and most importantly QUIET bite of the OEM pads.

At the risk of Hijacking this thread...

I overheated my M5's stock brakes at Cayuga. Not to the point where they were fading badly. They still worked but I was thinking about using two feet on the pedal! It was fine most of the day until an instructor started encouraging me to brake later and harder.... after a few laps I had to tell him that I couldn't brake any harder.

Anyone have a Brembo setup for sale??? Honestly, If I need to improve my lap times, I need to A: gut the car B: get a lighter car C: more lessons

How old is your fluid? That could have been too!
On a tight little track like Cayuga, I did not overheat my brakes.

Very fresh actually ... I changed it out after the WBR pads fiasco. Well, if not for the instructor, it prolly would have been fine.

Now that I think about it...maybe it wasn't overheating... maybe that's all the braking power available. Pedal wasn't soft at all and it didn't smell.
