Well, since you asked...
how have those wheels held up? any problems....
I've noticed that the corrosive brake dust from the Audi brake pads seems to be adversely affecting the semi-gloss black finish on the sides of the spokes. As time has gone by, I've noticed that the black paint finish in the areas where the brake dust collects most heavily appears to be deteriorating (for lack of a better word). It's hard to describe, but essentially it's as if it's wearing thin almost like they didn't apply enough coats of paint when they made the wheels.
The deteriorating black paint is more prevalent on the front wheels than the rear. I'm guessing this might be because more brake dust accumulates on the fronts, and we all know how corrosive brake dust can be. However, I wash the brake dust off quite regularly in an effort to try to prevent the brake dust from causing any type of corrosion on the wheel finish. I've also applied wax a couple of times for protection. Fortunately, you can't really see the problem from a distance. But, it is noticeable when I get up close to the wheel (like when I'm washing them).
I notified Wheel Experts about the issue and they contacted Work, who in turn, said they would look into it to see if any other Varianza T1S customers had reported this problem. Apparently, Work have sold a lot of those wheels to places like Senner Tuning in Germany, but supposedly no one has reported any problems with them.
Since the wheels are custom made to order, it could be that I happened to get a guy at the factory who was lazy and didn't apply enough layers of paint or clearcoat. That's my thinking anyway. So, I'm just continuing to monitor the situation. If it continues to get progressively worse, then I'll have Wheel Experts get back in touch with Work to get me a new set of wheels under warranty.
