This needs to be stickied ASAP!
Thank you for writing this! I was just about to grab a set from them, thank god I didnt'! If you are looking for some quality drilled and slotted rotors, check out 88rotors. They have warranties that cover one year for premature warping and lifetime against cracking! I'm not sure were they are manufactured and what not but I've had them on for about a year now on my e90 and other friends of mine said they haven't even gotten close to having the rotors warp or crack even after 5 years of harsh racing conditions. Its only around 300 for the front and rears! The only problem that I seen with them is if you spray off the anti corrosion coating, it really does rust
Other than that, they're amazing. I've went thru 2 brake pad changes and it only has a tiny tiny lip. They don't wear out fast like oem but fit to oem specs 100%. They're ready for direct swap even on stock pads and calipers etc.
