Two years ago, I first drove on this racetrack. At the time, the local Audi club chapter finally opened it up to solo signed off drivers with no instruction.
And of course, there was this still seared in my memory:

My brother took a bunch of pics, so I’ll have to get them from him. But here are some videos:

I absolutely love how the car handles around a race track. I do plan on getting stickier tires (and suspension mods).
One thing I did encounter, was brake heat issues… I boiled StopTech ST-660 fluid which resulted in me losing braking (for Turn 3 - which is a sharp off camber left turn after a down hill section). I was ready to take the car off the track but pumped the pedal a few times and got enough brakes to make the corner. I had built a big enough gap with the car behind me that I overtook so I could limp it back to the pits without causing a back up. Though when I got to the pits, the checker flag came out so I headed back out for a cool down lap.
So there I was bleeding my brakes at the race track using a can of brake fluid that I got from my friend (who works at Achtuning) and my friend’s power bleeder (I now have a track kit that consists of two cans of brake fluid and a power bleeder - as well as a bottle of motor oil - though the car doesn’t burn any oil). Fluid came out dark and bubbly (signs of very boiled fluid).
So with this, I’m going to have to address the overheating issues next. Tires and suspension should increase surface adhesion (which translates to less brakes), but I also need a bigger rotor (only Brembo has something out, and it does cost a pretty penny). Goes without saying that the dust shields will be coming off too… 
But as with all my other mods, it will come in increments (so I can feel them out on the racetrack).
I also found my jar of temperature paint, so I will be using that as well.
I do NOT ride the brakes. I brake short but very hard and trail brake quite a bit. There’s a hypothesis that I’ve been throwing around with the guys at Achtuning that the ASR might be using the brakes when I do not. So I might try a session without ASR, and then run a session like normal (driving style unchanged), and see how hot the paint gets. That or I’ll pull in and have my buddy shoot my brakes with a IR thermometer. It’s fun trying to figure these things out.
I do plan on keeping the RS5 for quite a while. And eventually, I’ll be trailer-ing it to track days too.
Anyways, enjoy the videos. I’ll post pics later.
