as teamrx8 stated, this kit will require a big spacer for the wheels to clear the caliper....lots of brake kits out there now are somewhat counter productive......anytime you add a bigger heavyer rotor you almost always are going to affect stopping distances........the brakes will be more consistent because of more pistons in the calipers and bigger rotors....but the stopping distances will probably not improve over stock......the bigger components will just reduce fadding of the brakes.....Thats why the racingbrake bbk kits are the best out there in my opinion.....you are losing rotational unsprung weight of the rotor (3lbs) and the caliper as well (6 lbs).....so your stopping distances should be reduced as well as reduction of brake fade should occur.........

RotorManiac: Yes it is the AP4600 kit and it actually uses the CP6600 caliper unlike the RE-Amemiya Kit which uses a CP5200 caliper.

mazdaexe

which pads did it come w/?

Thanx

hogcar

What are you doing with the calipers that were removed?

RotorManiac

thanks... now lets see them on the car

This is what the Racing Brake 2pc rotor looks like (Calipers coming soon)





...And yes I know the wheel is dirty!

Silverarrow

Mazdaexe: It comes with the Ferodo DS2500 pads currently. As soon as the Mintex Xtreme pads are available I will be picking up a set of those.

Hogcar: You have a PM

takahashi

SA!!!!!!!

Look good mate.

What a choice of caliper ...

Let me know what it is like when you run in the pads.

Silverarrow

Thanks Taka, I can't wait to get them on, this weekend for sure! I'll post up pics on the car when I have them on. Might be putting on the new coilovers too...we'll see.

Congratulations, you've just purchased a set of Brembos wearing AP Racing logos. Still, they'll work great!

Silverarrow

...no, you're mistaken. These are AP Racing Calipers from AP in Coventry, UK.

Silverarrow

Alright fellas, I got them on! Here are a few pictures, I'll post a more detailed install later. No driving impressions yet, but I'll post those as soon as I get out to bed-in the pads.

All I can say is WOW!

takahashi

What spacer are you using for the kit?

Silverarrow

The spacer is an 18mm bolt on unit. My particular one is sourced from FEED.

takahashi

I think they are 18mm front and 23mm rear or something. No rubbing?

I have a +32 offset rim Wedsports TC105N for track. +40 Enkei RP03 also clears...

What is the clearance of the stock wheel after the spacer put in?

Silverarrow

Yeah, that's correct. No rubbing at all. Clearance on the tires or clearance on the brakes? Both have plenty of clearance. I'd say probably 7mm clearance on the caliper easy.

I'm definitely going to add Wedsports to the possible wheels once I start looking.

bruce_van

Those brakes do look pretty damn hot.

Did you keep the rear brakes stock?

takahashi

He has to, unless he does not want the e-Brake. .

I wish there is after market ones that ties with the eBrakes.

Silverarrow

Yeah, Taka is correct. The rear caliper is also cable operated for the emergency brake. So unlike the Evo/350z/almost any other performance car on the planet that has a drum in the hat of the rear rotor, we are stuck with what we have. You could potentially change the caliper out and add a second smaller e-brake caliper, but it probably wouldn't be worth all of that work.

So I kept it simple and got drilled/slotted rotors to match the front rotors.

RotorManiac

hmm, I didn't know that. thanks for the info silverarrow.
after you told me that the amemiya kit uses the 5200 caliper, I spent some time reading technical info at the official ap site... I still haven't decided what should I get, so I come across these 2 tables and I'm not sure I can fully understand the differences. have a look
http://www.apracing.com/roadcar/cali...?family=CP6600
http://www.apracing.com/roadcar/cali...?family=CP5200

ok, your caliper is just a bit heavier, but uses thinner disc, 30mm instead of 32, which means is lighter, right? does the disc thickness affect the braking? I really don't know, that's why I ask...
and something else. the offset of the 5200 one is smaller, so I think it protrudes less (or is it the opposite?). I'm just trying to find out if it will fit my car's +38 offset... can anybody else, experienced in brake upgrades, comment on this? thanks

takahashi

RotorManiac,

I have the same kit. I was told this is much thinner than the 5200 model. So I need less offset from the wheel for the spoke to clear.

The offset from the website is prob not for the wheel but for the disc??? I dunno to be honest.

My CP6600 is using stock size disc. 328x28 Project Mu disc.

In the past, the CP5200 will be the go because you can buy any pad in the word.
Just until recently, there are minimal pads made for CP6600. Now, you can get Endless, Project Mu, and Seido Ya from Japan. So now there is no difference.

Cp5200 is prettier, CP6000 is smaller.

In terms of clearance for real life, read a few post earlier

RotorManiac

oh, I didn't notice you writing this, thanks. this is good news, but maybe I should just email AP to be sure...

I have to agree with that.......

Silverarrow

Hey Rotor Maniac,

The only way to know for sure if it will fit your wheels is to check with the attached template. You just drop it into the back of the wheel and make sure you have enough clearance.

Also, I JUST got an email from STILLEN and they are doing a special on the RX8 brake kit! It is $277 Off! So now might be a good time to take the plunge.

I haven't gotten to the track yet but plan to get there next weekend for the Redline Time Attack at Fontana. I'll be putting them through a torture test there for sure!

So far in street driving the pedal is very easy to modulate and every nuance of your foot translates into instant stopping power. I had stainless lines before and that was a nice improvement in "immediacy" but this blows that out of the water!
