i have the oem brembos and w2 pads. they still dust but not nearly as bad as oem. They seem to be pretty good for autocross and they dont squeal

Most pads will be noisy with the AP Sprint kit, unfortunately.

Have you tried shims + brake grease with the W3? That may help, as long as you don't get the W3 so hot that you burn off the grease.

Just want to clarity. You are using this on the ap racing sprint kit?

Nope didn't realize it made much of a difference vs pad choice.

Anyone running AP racing sprint with winmax W2 for street? Care to share your experience? I'm running carbotech 1521 and it's relatively quiet on street but I want something more aggressive without squealing.
Winmax w3 are squealing like crazy.

Did you bed the pads in properly? There's nothing inherent to our AP Sprint Kit makes it any more prone to squeal than any other brake kit. In the vast majority of cases, squeal goes away to a great extent after a good pad and disc bed-in.


Here's the bed-in video we did years ago...sorry for the crummy quality!

Here's a related one on swapping pads. It gives some good insight into the reasons behind squeal:

Prior to bedding, the brakes were quiet until u start using them. 1-2 times is enough to make them squeal like crazy.

I went to bed the brakes using the following procedure.
Using 60-80% of pedal pressure, decrease the car speed from 80 km/h (50 mph) to 20 km/h (12 mph). Repeat this process 7-9 times.
Do not drive the car to a complete stop as this will increase rapidly the temperature of the pad.
Repeat the procedure from 120 km/h (75 mph) to 80 km/h (50 mph), and from 120 km/h (75 mph) to 20 km/h (12 mph).

After bedding they SCREAM!!

The rotors looked like this after I cooled them down by driving on the freeway for 10 min

I'm not sure if this means the pads are overheating or I need to continue the bedding process.

Any ideas?

I have AP Racing endurance kit on my FR-S with Carbotech XP8 pads. They sounds like a screaming banshee no matter on street or track and no matter how hard I tried to bed them in. But the combo works great on track, I have zero brake fade with 30-min sessions at Laguna Seca and the rotor wear is minimal.



For street driving (which I rarely do on my 86 now), I currently use StopTech Sports 309 pads (yes there is a pad shape matches AP racing calipers) and they are almost silent on street. They should withstand higher temperature than Carbotech 1521 pads and they are almost half the price. The parts numbers are:



Front (for CP8350 caliper): 309.80210 (which is usually under $60)

Rear (for non-brembo 86): 309.11240



I do have to remove the shim came from front brake pads to make them fit but still they are almost silent on street. Hope this info helps you.
