I've got the HPSs in my Brembos. The fronts make a half-second sqeak once every two weeks or so. I did have to grind the sides of the backing plates a tiny bit to make them fit. The rears are quiet but clunk around in the caliper when I change from going forward to reverse. As in, back up, brake, ::clunk::, put it in 1st, go forward, brake, ::clunk::, then they're fine.

I bedded mine in like a ****. I found the most agressive bedding procedure and went with that. The whiplash was worth it. The next week, with 150 lbs out of the car and a light tank of gas (putting the car's weight at just under 3,000lbs), I could stop in an average 93 ft 60-0. That's 5 runs, 3 one way, 2 the other, best stop was 86ft, worst was 99ft.

Sorry, just thought I'd share. Also, when I bring her down from 60+ to 0, my speedo is still reading 20-25 mph when the wheels stop moving. This car stops faster than gravity can make that thing fall!

edit-sorry, this was also on the RE040s too.

 

I have them in the front. They squeek at low speeds (i.e. coming to a stop) more often than not. They were installed at Speed Image and Eric broke in the pads for me; therefore, I'd assume the break-in procedure was properly followed. They are not that unbearable b/c I usually drive with my windows closed. Also, the exhaust note and the music may contribute to the fact that the squeeking sound doesn't bother me as much as they do others.

 

after reading this maybe I will get my dealer to put mine on. do they charge much to install

 

of course they squeak, theyre high performance brake pads. 99& of performance brake pads are going to squeak, theyre metallic, and our stock pads arent.

 

Same thing here. Lots of low-speed squeal until a track event, then quiet as OEM pads.
