I installed front and rear Z36 Power-stop kit with slotted rotors a few months ago on my 2019 and have not looked back! Very good upgrade. Look on Amazon, they have great prices and on sale a lot of the time.

they positively affected your brake performance 0%. You just reduced the rotor surface for your pad to bite into.

There's a whole lot more going on during braking than just surface area. Gasses roughly expand at a 1,000:1 ratio. The pads and rotors are an engineered pairing and work very well. I've come across several engineering designs that, from the outside looking in, appear to be less effective but are actually designed appropriately. Far exceeding what you'd believe to occur due to the entire system working as designed. Clearly the numbers powerstop is seeing on their brake dyno differ from your perceived value.

Where it does not lie is the race track. And there are no such designs in use on the race track. The only numbers powerstop are seeing are their bottom line. Its a marketing gimmick.

Race cars don't use them due to the much increased stress on the rotors. Sorry. Using that as an excuse is the same as saying we use the same brand oil as them when they don't use anything similar.

I'm sorry but you have that wrong. If there were an edge, the design would be used. No sense in arguing, spend your money how you see fit ?

No sir. We use 5 20 oil because it is optimum for our engines. Race cars use oil that is as thick as water. My race boat had very little in common with a normal boat. Two different uses. We don't use race tires either do we? BTW, most high end sports cars come with drilled and slotted rotors.

Ok we can argue. I use 20w50 in my race engine which is toleranced for it by my engine builder. It's a boutique oil not off the shelf. My BMW has drilled rotors. My race car has 100 tread wear tires. The brakes are 2 piece slotted rotors with aluminum hats, made in USA. Running 4 piston brembos with aftermarket vented pistons, titanium shims and high temperature seals. I run Castrol SRF brake fluid which is ultra high temp. My brake rotors can glow red and I will not lose my pedal, lap after lap.
Many many of the components and products used on street cars were developed on the racetrack. I promise you powerstop rotors aren't one of them. Show me one OEM that run drilled and slotted rotors.

Not to mention Powerstop rotors are made in China. But as I said it's your money, buy what makes you happy.

+1 on semi-metallic. Ceramic pads are about low dust and NOT performance.

Different use cases. A lot of race formulations need to be hot to perform. There are no free lunches.
Dozens of vehicles come out of the factory with drilled rotors. From BMW, Porsche, Mercedes, Lamborghini, Ferrari to Nissans. Surface cracking occurs on all rotors and isn't unique to drilled. I've pulled dozens of cracked OEM rotors off of vehicles.

The rotors on my 1998 Chevy Tahoe were warped at 28,000 miles and so I replaced them with high performance rotors and calipers and they were in great shape when I sold the vehicle with more than 170,000 miles on the odometer. The OEM parts were cast and the performance parts were machined and provided better ventilation.
The high performance parts cost me no more than the OEM cast parts purchased from the dealer.

Gosh, I can go back to 1985 on my Suburban with 50 gallon gas tank, 3 kids, the old lady, and packed to the gills for vacation. I was warping rotors right and left. I mention it to my bud, who built his own cars and raced them. He bought me a set new GM rotors, slotted them, added a hydraulic power brake booster, and I never warped another rotor. Went 340,000 miles in that truck.
Finally bought a new 1999 Suburban. It had no brakes whatsoever, but that is another story. Traded it for a 2000. Only put 200,000 miles on that one and never had to do slots and never warped a rotor. They had jettisoned the 50 gallon tank by then and I gradually jettisoned 3 kids to college, marriage, etc. The wife has yet to jettison me.
Still don't need nor run slots or holes on anything but the 2018 Z06 with carbon ceramics.
Speaking of carbon ceramics, no one has mentioned these but most have said they need more brakes. If someone truly needs more brake they will stop the BS and go full carbon ceramics. Conversation over.
