Re: In Defense of J55 Brakes
 

Pads make a big difference. When I autocrossed all the time, I put on new pads every year and once accidentally switched from Hawk HPS pads to HP+. I daily drove the car and the HP+ likes a little heat. The first stop or two of the morning commute the brakes were plain weak. After 6 months of scaring myself and a close call or two I gave up and switched back. The Plus pads technically had better specs but weren?t best for my application. The HPS pads didn?t stay hot in autox they way they would have for track day use and worked better than Plus at everyday temps Lately I?m using HPS 5.0 on the ZR-1 and am happy so far.

Just be prepared to go through rotors faster. Benz uses soft rotors to begin with, which further enhances the braking performance.

I picked up some Brembos that are better

Re: In Defense of J55 Brakes
 

when i put the brembo's and ccb rotors on my 2007 z06, i put the z06's brakes and wheel/tires on my 1991 zr-1. have not done any comparisons but they work.
#1 c6 z06 caliper vs c4 j55 caliper
#2 c6 z06 brake assy on c4
#3 rear z06 rotor vs c4 rotor

ps. how do i rotate a picture cw/ccw?

Be sure to install the DRM bias spring. It makes a noticeable difference.

What wheels are you using

Re: In Defense of J55 Brakes
 

As my Z still has the factory installed rotors and pads I'm thinking about some modernization, too, maintaining the stock setup. Powerstop Z26 would be the stuff of choice for me. Just one consideration: are these slotted and drilled disc's really anything as close to "quiet" as powerstop claims?
I used to have drilled rotors in the past in one of my Audi's and these were an awful choice as they caused buzzing/humming noises and even slight but noticeable vibrations up to the steering wheel.

When speaking about stock brakes also noise is a consideration as my Z is a Sunday Sunday afternoon bullet and not a track tool...

The Z26 package has been quiet as a mouse for me. I?ve been using it over a year now and no noise of any kind. The rotors are zinc plated, so it is a nice touch and good to know you don?t have to look at rusted parts of the rotor not in use. Low dust pads. The only thing that you might even consider an issue is on the rare cases there is enough pad dust accumulated that gets wet from say driving in the rain, it can run out onto the wheel and dry out. It requires some extra effort to remove from the wheel but a very minor issue.

Great, thanks for that insight. Then I will order my set! Seems to be a wise upgrade.

If u are going to go w 18/19? wheels like the OEM C6Z 5 spoke, the stock calipers and rotors look puny.
What I like about the bigger brake, beyond the aesthetics, is how light the pedal pressure needs to be to stop in typical driving situations. I end up stopping sooner than I think I will.
