and the V-6 1LE is two seconds quicker around the track at GM’s Milford Proving Grounds than the fifth-generation SS.


Ummmm.....wow....

For track duty quite often is better to not have slots and for sure you do not want drilled rotors. Too big of a chance of cracking. If Plain Jane rotors work fine fade free there is no point.

Drilled are definitely a bad idea. Slotted, though...there is some use for slotted. The C7 Z51 rotor is slotted and the Z06 is drilled. The rules may be different for a carbon ceramic rotor.

I've read/heard many times that a slotted rotor helps with outgassing, which keeps the pad from pushing away from the rotor when it heats up.

You know that any components from the factory are going to be top of the line quality wise and have been tested, thoroughly. I don't think you have anything to worry about if you use the GM slotted rotors at the track. It was probably a move to save $ and keep the cost of the car as low as possible. People are going to chew through rotors that track it regularly anyway, so I don't think it's a big deal. They do look pretty nice though.

I'd be more concerned with a proper track pad vs the rotor. And changing out the fluid

Slots provide more for keeping the pad-to-rotor surfaces clean and also a tuning aid in pedal feel. From what I understand, and this is coming from a conference I went to put on by one of the major racing brake pad companies, that, YES, even new pads do create some gasing that is beneficial to eliminate in high levels of competition. In lower levels and for track days, it isn't much important as the amount of gas is considerably less than what it was many years ago when the hype for drilled an slotted rotors started.

Solid face rotors will do 99% of what is needed, the most reliably. If you need more for one of the three reasons above, move to a slotted rotor. Stay away from drilled rotors. The only ones worth anything are the expensive ones that have a lot of engineering behind them. Otherwise they are a big risk in failing on track.

Does the patented treatment on the rotors from GM make them last any better than regular rotors?

Did I miss something? What is GM's patented treatment?

OK so they've been using it sing 2008. I guess if you don't track your car that'll definitely extend the life span of a rotor.

[6spdhyperblue]

Ah good info, never knew what it did specifically

[BaylorCamaro]

I wouldn't be worried about slotted rotors, especially factory slotted. I have nearly 1,000 track miles on my '16 C7 Z51 with a very very aggressive race pad and I'm still on the original rotors.

Seconded.

Change your fluid...and the car will likely out-drive you, until you get better...
