Looking into replacing my rotors here soon, the lip is starting to get noticeable lol
Question is, stock, powerstop, or other options I have not heard of?
Currently using powerstop’s z26 pads as they are a must have for getting rid of the excessive brake dust, and am going to continue using them with a new set.
Just not sure of powerstop’s drilled/slotted rotors. Really dont care for the drilled and slotted look and whatever benefit they may give, but they are lighter on the wallet than the stock rotors, any thoughts, recommendations, and input would be greatly appreciated!

I would go stock. How long did they last you? Ambiguous I guess - as it depends on your driving habits, but still, how many miles?

I have heard/read that the drilled and slotted rotors have a pulsing feel to them when braking. Is that true?

Have had drilled on two c6 vettes over 90k miles total. Never had pulsing. Supposed to cool better.

Thx, was just curious. I've read that the slots in the rotors causes pulsing. I've never had drilled & slotted rotors, but I'm thinking this spring I'm going to put on the PowerStop kit

Assuming you're gentle on them with only normal street driving you'll likely be fine either way and at that point it's really just personal preference. But, if you're doing any heavy braking on the street or track use I'd stick with stock rotors for the following reasons:

1) Stock rotors have more mass and are better at handling the heat generated from braking because of it. They'll last longer than anything slotted or drilled, so keep that in mind when comparing prices.

2) Drilled and/or slotted rotors don't have any real performance/cooling benefit unless you're running a serious brake setup on track with aggressive track pads. The voids in the rotor create stress concentration points which turn into fracture creation points, especially with drilled rotors. The thinned-down portions will also heat up and cool down at slightly different rates than the solid-face rotors which can also lead to premature warping.

I have used Centric rotors on all my vehicles for the past 10 years. Great value and better corrosion control.
I have not put them on the Camaro yet, but this video confirms they are available. Saw it on the internet, so must be true!

stock is just fine

When the time comes, I'll go with stock

You will definitely hear audibly and feel in the pedal the difference between flat and slotted rotors.

It may not be a "pulse" as some would associate that feeling with warped rotors etc.. but you can feel it in the pedal.

Rotors with a lot of surface area removed for slots and holes have less area to stop your car and that less surface area only becomes better than flat when you are exceeding the temperature needed to cause outgassing of the pads and overheating of the rotors (frequent high speed braking). For normal braking, you'll notice they cause worse braking performance and higher pad wear than necessary. So if you're not tracking the car, you're getting them more for looks than anything else.

i'd suggest the flat kind unless you're really keen on the looks or tracking the car.


something to consider with even flat rotors is how they are vented. Super cheap rotors may have visibly less venting (as seen from the edge of the rotor) than more expensive rotors. So cheaper rotors will tend to warp when used in vehicles that rely on really good braking due to the weight of modern vehicles or performance.

(edit, i'd be wary of slotted/drilled rotors being cheaper than flat rotors you're looking at because they may be using rotors with less venting and likely cheaper stock (less quality steel even) to boost their profit margins - which can lead to cracked rotors or warping)

Great info...! Point 2 maybe exactly why people post that drilled and slotted rotors have pulsing.

Sounds like it might just be better to switch to the PowerStop pads, but leave the OEM rotors.

Much appreciated, think I’ll get a new stock pair then

Been running the z26 kit (pads and slotted/drilled rotors) for the last 6 mos. and they are a significant upgrade imo. Perhaps not for daily driving (although outside of less brake dust I've noticed no difference) but I live near the smokie mountains and visit the Tail of the Dragon and other roads in the area twice a month on average. Here you will notice a difference. My first trip up there in the Camaro, the OE brakes faded like crazy and started to smell strongly after just 2 passes, causing me to lose faith in the car and leave early. Immediately ordered the z26 kit and haven't encountered the problem since. Now I did swap fluid and lines as well, so keep that in mind, but I'd definitely recommend the PS kit over the stock rotors/pads if you do any aggressive driving. Those holes aren't just there for looks, they dissapate heat very well. The slots don't but they do "scrape" the pad clean of dust and induce better pad/rotor contact. There's a reason Porsche and BMW use these type rotors.

Yes the brake pedal does feel slightly different, but it doesn't pulse nor feel like there's anything wrong. It's just different.
