I have the 2007 C6 with the Z51 brakes. I am looking for new rotors and I wanted to see what everyone recommends.

Thanks

 

If you were satisfied with what you currently have for performance, then continue with OEM. Other than appearance, nothing else will make a difference.

BTW, welcome to the forum.

 

Thank you!

 

RockAuto online has them for 59.79 fronts each, rears are 38.89 each, AC-Delco..

 

I'm considering this kit with the Stoptech pads that come with it instead of the Hawk pads. That's only $110 per corner which is pretty good.

Just a note;
The OP should not consider these as he has a Z51 optioned car, which have larger diameter rotors.

 

Looks like the have a kit for the Z51 but is more expensive.

Thanks for the link, though I will use the OEM's @ $200 plus pads, when the time comes to doing my brake job soon, since I have about 44k miles. I have not need to upgrade as my car is used as a daily driver.

 

There are AC Delco "Professional" front rotors, GM P/N 19203421 (ACDelco P/N 18A2429) for $59.79.

There are also ACDelco "Original Equipment" front rotors, GM P/N 89060328, (ACDelco P/N 1770924) for $86.79.

Both are listed for use with Z51 (J55) heavy-duty brakes.

Has anybody compared these two rotors in person? Are they actually different?

 

DBA 4000 series slotted

 

Zinc plated slotted rotors in the J55 sizes will be fine if you not pushing the car too hard, plus you don't have to paint the hats from rusting in a few years like the Oem drilled rotors isntead.
To note, if you get the oem rotors, there is no left or right hand sides to the rotors. Hence the veins all all angled like they are all left hand side rotors isntead.




Two piece rotors are better if you are pushing the car hard instead.


Also, before you call the rotor's toasted, see if there is enough metal to just turn the rotors isntead. Yes, drilled rotors can be turned (just not so deep per pass, and they have to make sure to install the dampening belt around the rotors or use the brake lathe has dampening pads so the they don't end with a bunch of chatter.


On mine, I went through brake pads in 30K, but the rotors had enough meat still on them to be turned to get 60K/second set of brake pads out of them instead.

And yes, took the time to paint the rotor, but need to be touched the paint up now that I have some miles on them again.


And yes, running Z51 HD pads, and you can see by the barrels dusting, hence these pads to dust more, but worth it for the initial bite, feed back, and working temps of the pads that they offer isntead.

Lastly, when you do have the rotors off, take the time to adjust the rear brake shoes correctly as well.

I highly recommend Brake Performance Cross-drilled & slotted rotors w/their Premium Semi-metallic pads. I had them installed to replace the stock brakes on my 2008 Coupe I had before. The brakes are top notch in quality w/a price tag that beats out about everything out there that I had found. ( http://brakeperformance.com/brake-ro...=impact.radius )

 

Really lost on the whole drilled and slotted thing (since you gain nothing but looks).

Drilled rotors helps the dust /gassing clear, and allows the rotors to cool due to the added vent holes, but the drilled holes also cause heat stress points that will allow the rotors to crack if they get too hot instead.





So for racing rotors where the heat is going to build up in the rotor, then slotting clears the dust/gassing (what drilled holes do a well), But you don't using any drilled holes so you don't have the cracking placement problem isntead.

 

You bring up some great points Dano. Those were some things I was considering when I decided on the Drilled & Slotted from B.P. (I wasn't planning on racing my car, so that was also a factor) The drilled & slotted had a lot fewer holes than the straight drilled rotors that they offered. The drilled & slotted rotors seemed like they would hold up better than the straight drilled ones. On an equal cross section of rotor there would be a lot less metal holding together the drilled ones.

 

Baer makes a really nice rotor for the Z51.
