I ordered front/rear drilled/slotted rotors from R1 Concepts Yesterday (Thurs 8 May) and I got them today (9 May)...Thats what I call fast svc...

 

Awesome

I just now got done upgrading my slotted to cross-drilled Brembo rotors. I am not sure why I didn't get drilled to begin with last year when I installed the brakes the first time [>:]

Nice bro, they make a huge diff. I noticed a diff before I left the driveway. The car cam to abrupt stops vs smooth stops because the pads weren't gripping but rather sliding. The slotted parts hleped out alot with that to keep the pads clean. The drilled helps with highway abuse. I love'm and will never go back. I may however not be so keen to putting them on my winter car as they are prone to crack with excessive hot/cold. Slotted one's are best for all temps. Drilled/slotted for warm outrageous abuse...lol Enjoy!!!!
