Ok...shop quoted me >$400 to replace with oem the rears. I want to keep budget under $450.

I occasionally autox, but not often at all. I more care about show now. I would like crossdrilled/slotted rotors that will stay as beautiful as ETs (which, btw, I'd like to see how he does that but can't find it).

On to rotors - I want no squeal, good grip, and little/no dust. I hear the Hawk HPS pads are good, but would like to know how much dust they put out. LESS IS MORE!!!

Finally....what do you guys think about those ebay rotors?

In closing, thanks!

 

If you can do the work yourself get the Napa D&S rotors for$55 each

 

Any brake pad that is really good at stopping is going to have a higher level of dust and noise. I know the Hawk HP+ dust a lot and the the Hawk DTC-70 are crazy.

If you want less dust Hawk makes a "performance" ceramic.

BTW - I would not recommend cross drilled rotors if you are doing Auto X. Cross drilled rotors have less surface area for the pad to bite on and also have a greater chance on cracking.

 

and changing the rotor is easy. Basically 2-21mm bolts and maybe a retaining clip or 2.

 

yeah I'm going to do it all myself. The ebay d/s rotors are cheaper than napa...are napa zinc bathed?

I thought ceramic brakes caused alot of noise? Would those Hawk Ceramics be noisey at all? What are their downsides?

Don't worry about the autox part...if they don't perform well I'll just get a different setup which I'll switch the day of.

 

ceramic pads make least amount of dust and I believe they do not make noise. I have never run them because they happen to have the least amount of stopping power and for what I do it doesn't make sense.


With the rotors if you understand the D/S are more for show then anything else then that is your choice.

The only concern with the eBay rotors is if there are made in China or not. If they are then for them. The NAPA ones come from Canada which most good rotors come from. I use the blank NAPA rotors for daily and for HPDEs. They are good quality.

 

IMO the ac delco drilled and slotted rotors and ceramic brakes are fine for starting HPDE’s, and great for the street Cheap, quite, low dust (I don't think its a problem). Check Fred Beans they have pretty good prices.

I’m just starting HPDEs this year and that combo has held up pretty well. I’m just beginning to experiment with different brake pads, so can’t compare them to other pads. However, if your just starting out in HPDEs or autox then you have a lot to learn before upgrades to the brakes will help out. Or at least I do IMO you'll find out what you need after some experince balanced with input from others.

The ac delco rotors are usually kept shinny by using a high temp paint, at least 1200 degree paint. Some use clear and some use a aluminum or similar color on the hats (the center portion and on the edges. Don’t try any paint rated less than 1200, I tried 500 and it cooked to a fine brown color the first HPDE day, on the auotx it was ok.

If you are comfortable with the seller on e-bay and you know that you are buying genuine reputable parts, then e-bay is ok. What made sense to me was the speculation that cheap rotors or poorly manufactured drilled and slotted rotors were to blame for the reputation for limited longevity. Why would they put drilled and slotted rotors on the C6 if they were a source of problems? But buyer beware!

 

Ceramic pads are the worse pads for stopping. Why would you want to run a HPDE with pads that will not stop you. If you were not ready for a race pad (It took me about 10 or so track days until I moved up) then at least go to a pad that is an aggressive street pad or a street/race pad. At the same time I would change to better brake fluid that will not boil.

There are plenty of articles on the web that state drilled and slotted rotors are not good for racing events.

Here is direct quote from Tirerack

"IMPORTANT REMINDER: Slotted, drilled or dimpled rotors offered as OEM replacements should not be considered appropriate for high-speed track use.

While grooved, drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they are not designed to withstand the extreme temperatures that are produced on the racetrack. If they are used on the track, it is very important that the rotors be carefully inspected and should not be driven on if even minor signs of deterioration are seen. Note, too, that if any products are used on the track they are not warrantable."

Here is a quote from S2K website

"A few words about drilled/slotted rotors… These are supposed to make your brakes more effective because they presumably cool better than solid rotors. While this is probably somewhat true, these should almost never be used in performance applications. A drilled rotor is a weakened rotor and is much more likely to crack under high temperature conditions. The holes also reduce the surface space for the pads to make contact with and therefore reduce friction. (stopping power) While slotted rotors are definitely stronger than their drilled counterparts, they too offer the disadvantage of reduced surface area and therefore less stopping power. For high performance/racing applications, solid OEM rotors will stop you as well or better than just about anything out there.

 

So what of the Hawk HPS pads or the Hawk Ceramics? What are the +/- of those?

 

Ordered the SportBrakes rotors and Hawk Performance Ceramic pads...I'l post how they work out after the install!
