Question about R1 Concepts Rotors and Pads
 

Thinking about ordering a set. I have two questions for anyone who has them:

What's the difference between OEM Design Aluminum Hat and Optional Design Full Cast rotors? These will be replacing BMW stock rotors.

What type of brake pads do you recommend?

R1 concept suck, they warped on me within a few months. Contacted the vendor and they were silent. Now I know why their price is so attractive.

So they are all show no go, great if you have a show car and just want to have some cool looking brakes.

Agree with Boost7, Basically they advertise that it's made by so & so. But what they do is get these in bulk from China. Then they pay for packaging and print.
