the brake rotor is warp and shaking easily at high speed

I have always buy OEM genuine brake parts as I used to believe what I pay is what I get. Now I realize that Acura is dong business like Printer company - cheap printer but expensive cartridge. Acura OEM brake rotors are so easy to warp at high speed. I agree Acura SUV is fairly affordable price and they make it up by selling expensive OEM replacement parts. Now I realize Acura OEM parts is even more expensive than Lexus - I own another Lexus car now. I am very disappointed with Acura about this.
