There's some very light cross-hatching but nothing serious. The contact surface still look dar v. the picture of your rotors.
How many street miles did it take you to get them to feel seriously good?</TD></TR></TABLE>
I wouldn't worry about the fact that you had them mounted backwards. I think the buttons still perform the same function as every other rotor out there, it's just that the fingers are active only in one direction.
To answer your questions: It took at least a full season of street riding to get good power, I'd say over 6k miles. Like you, I remember thinking "these aren't so great". You need to break them in completely. The photo below is the rotors on my bike during the first year. You can see all the grinding marks, the marks that are perpendicular to the rotation of the rotors. You can also see the original carriers with the little pads.
Compare that photo to the one below it which is the same rotors a year later. The carriers were swapped out by Brake Tech (gold this time).
Now, my bike is an ST4 so I use it for touring and Blue Ridge Parkway sport riding. My usage is light compared to track day riding.
I would say that the brakes on my ST4 started working really, really well, with one finger power, after the grinding marks disappeared. On my bike that took a good 10k miles.
And for me the Platinum pads feel the best. I tried CP911* pads but they were AWOL in the rain. Platinum pads work best for me.
I wipe the rotors off with a cloth and some aerosol brake cleaner after every couple of long rides. And I pull the pads once a season and lightly flat sand them with 400 grit sandpaper.
You're going to love the iron rotors. Post back when you've had a chance to put some serious miles and heavy usage on them. Your rotors are brand new, and have an extreme pressure lube (Gun Kote) in all the low spots. Give it time.
