I have a set of RS5 ventilated cross-drilled brake rotors for the front wheels. These are the quintessential "wave"rotors. These are used, but in great condition. I believe that thickness on these is around 34mm new. These measure at 33.81 on both rotors and minimum thickness is 32.4mm. So, you can see that these have tons of lift left (approximately 85%).

A great OEM+ upgrade or if you are going with an R8 or RS5 look.

Retail is around $1800 for a new set. Asking $850 + shipping.
