Well I just had my new cross-drilled/slotted rotors and pads installed yesterday and they're great! I had slots on my car before this and they worked well but now I can really tell a big difference in this new set-up, especially the way I drive. They stop my car like you wouldn't believe which is good for me since I'm a late braker
I wanted to be a little different and went with a European product this time, Rofren pads and Bradi rotors. It's the same material that Brembo uses(from what I understand). The company that did these for me deals mainly with Euro cars but can make a rotor for just about anything on the road they told me. So if anyone cares to check them out just got to http://www.eurobraketech.com and ask for Dave if you call. You won't regret it!
Btw, I can take pics if anyone wants to see them. The ones in the link are my old slots.
