I got the EBC solid rotors which seemed fine - in the 10 miles before they warped (calliper issue BTW)...
The Premiums looked great but are probably noisy, I had grooved R1s on my WJ before and they are did make a fair bit of noise. Numerous people here reported having noises from drilled/grooved rotors. I found the HPS pads a little noisy too.
R1 concepts rotors are great though, I'd recommend their premium solid rotors and EBC Green Stuff pads or another brands ceramic pad.
