Any 9" wheel under ET35 is getting pretty aggressive. The B8 RS4 reps are just starting to hit the market, so I am sure you will start to see more (and they are now being offered in B8 fitment on the 2015 B8.5 S4).
Dig the Renn RS-51. Would have gone with those had I not already ordered a set of wheels.
I’d avoid ADV.1. I’ve read several bad stories about their wheels as well as their customer service. They have also been caught lying about certifications a number of times.
Have you ever considered CCW wheels? They are a very good compromise between extreme-strength!, light weight and $$$. Do a search on CCW c10’s or c14’s (Big in the Porsche / corvettes racing community).
Only sold by CCW.
Someone with decent precision machining knowledge like yourself would appreciate these wheels.

Here’s our new design. We didn’t have time to clean/finish the wheel before SOWO but it turned out pretty nice anyways - So the finish on it is completely RAW (it will not look like that when it’s done). It’s 19x8.5 ET45 on a MK7 GTI. Weighs 18.7 lbs is forged. We’ll look into more weight reduction, different offsets, sizes, concave, etc. Tons of brake clearance too.
I’m trying to see how viable these wheels would be. 18 lbs or so for 18x9 et 33 I believe, at a little over $300 per wheel http://www.getyourwheels.com/view-wheel/enkei-wheels/enkei-rpf1-silver-. They don’t make many with audi fitments, so I believe I’d have to run adapter rings which I’m not a fan of. Would run 265/35R18 R888 which would be a -1.6% rolling diameter difference from the stock 18" fitment. Advantage of that setup is I believe I could source R888’s from used track tire outfits. Not sure how positive you all are about that avenue, but tons of guys at the hpde’s I attended had used tires for around $400/set. Single heat cycled from a qualifying session. I’ll probably need to research how available that tire size is.
The other option would be tsw nurburgring wheels in 18x9.5 et 40 which would be a perfect fitment, come in 21 lbs. These would be only for the track, so I’d be trading looks for performance, since I think the tsw’s look a hell of a lot better than the rpf1’s.
