I do not have any of the R1's on my jeep but I do have a set on my 300C and I am happy with them. I had the same problem with my OEM rotors warping and once I got the R1's the problem was solved. I combined the R1's with some hawk brake pads and it helped my stopping power tremendously.
I dont know what the OP is talking about.......Ive had my R1's on for about 6 years, ALOT of hard breaking and ALOT of time on the dragstrip. Matter of fact, the last two years my R1's have been stopping me after going through the traps at 141mph......guess what.....still not warped. lol.
