As others have mentioned, your rotors look fine.
As far as other suggestions, for rotors I have used the stock VW rotors or OEM replacement with zero issues since I bought the car. ~10-12 track days per year + 15K DD. The biggest issues I have had to address is pads/fluid. After 3 years with DS2500's and loving them, I have had to switch to higher temp Ferodo DS 3.12 Front and 1.11 rear which have been fantastic. DS 2500's were starting to give up the ghost at the end of long warm sessions after going to stickier tires (Cup2's, Falken 660's) and also pushing later and later braking. I don't think FCP carries the pads, but as you mentioned, you can get the lifetime warranty on the stock rotors.
