Brake discs R1 Concepts or DBA

Its been just under a week after installing R1 Concept's Geomet drilled/slotted rotors and ceramic pads, I am impressed. Extremely quiet and smooth ride but once they're hot, they get aggressive.

I bought R1 Concepts front rotors for my Lexus IS250 at 85k miles. My car sits at 143k miles 5 years later and they have been the BEST rotors i have ever used. I chose their Geomet coating, and they are so rust resistant it is ridiculous. I have zero rust on the veins or hub of my brakes at all after all this time. I have used Powerstop rotors in the past on numerous vehicles, but I find the zinc coating will always rust after a few years. The R1 Concepts geomet coating is the best in my experience.

I have R1Concepts Geo-Carbon series rotors (2nd vehicle I’ve used them on), absolutely no complaints from my Giulia. I’m rocking them with Porterfield R4-S pads and the bite in dry is very nice and feels the same in wet.

R1 concepts slotted drilled rotors and pads along with some GoSpeed traction drop springs and alignment.

I’ve ran the R1 concepts D/S with OE Pads, steel lines, MOTUL 660 fluid. I’ve got them pretty hot on mountain road runs many times, no issues.

I just installed front axle drilled and slotted rotors, and new pads, all from R1 Concepts, and total cost shipped (Amazon) was $56. Tax, delivery, shims, everything but silicone grease.

Got a 2017 lancer and did the R1 concepts. Good results after only the first two weeks. Mind you! I had two seized calipers in the back and had to replace those as well. What is stated about drilled rotors is true about the cracking if you’re using them aggressively, I bought these specific ones because I read they have the better rating out of most and since I’m using them in the winter I’m not concerned with them getting too hot to crack (please correct me if my logic is not correct) but I assumed that since the vehicle was primarily being used for cold weather it would be best to go with a more reputable brand for safe stopping power.

Got the R1 concepts for the rotors and pads. Impressed by the braking power

R1 concepts are fine not the best.

I bought new set of rotors DBA 5000 T3, (floating rotors) and paired them with ebc rp1 pads. I have rbf600 fluid (around 1,5y old) and braided brake lines. Car is 370z.

Did the bedding in procedure, all good. Rotors have 300km, all works perfectly.

Today i went to a track day and did several very powerful brakings, but also did a cool down lap. And on that first stint, my pedal got soft. Ok, fluid will change.... But stopping in the paddock, the brakes were smoking a bit. I immediately rushed out and did a few km outside, cca 80-90kmh to cool the brakes down. Worked well, they were cool. But then i checked paint markings, all changed colors, indicating rotors exceeded 630°C.

And that was one short stint. So later when i drove, i was very gentle, all good...but i feel slight judder around 120kmh, and when i brake, the steering wheel shakes a bit.

Did i really manage to ruin completely new rotors in ONE stint?
