Please tell us you don't hit them with a hammer. LOL
In fact, our wing mounts are rather robust compared to, say, those on a B4.
There has been much "discussion" within the company about wing mounts. Because of their shape, it was a very expensive mold to make and it's an extremely expensive mold to run, requiring constant attention and work from the press operator.
But we want the wing stable, not flopping around, so that all the downforce is transmitted to the car. We want to use the largest legal wing to generate maximum effect, believing there is no such thing as too much traction. (Remember that astro and grass tracks are the exception, not the rule.)
Therefore the wing should be stable, and that means a stiff mount with a wide stance. Any mount like that will be a bit brittle. You can't have a plastic part that refuses to bend yet is not brittle unless you spend a ton of money on exotic materials which are usually full of expensive carbon fiber.
I believe the AE mounts mentioned above are made of nylon, one of the cheapest and easiest to work with materials available. Ours are made of polyeurethane containing 40% (!) fiberglass -- far stiffer and stronger, but more brittle. We could save a lot of money with the cheaper material, but tests show this makes the car perform better.
Racing is all about making choices. The best illustration is an automobile tire. If I make a really soft sticky tire I"ll get a fabulously safe tire with tons of grip, but it will wear out in just a few miles. If I use a compound that's hard as a rock it will last 100,000 miles but when my wife slams on the brakes it won't stop. So, in the tire business a designer must look at where the tire will be used and design a compromise that works in that setting.
X Factory is a pure racing company -- we assume that nobody ever runs one of our cars in the back yard. So we make decisions rather like an F1 tire designer. Our wing mounts are a bit more brittle than AE's, but the car is faster.
Another advantage of X Factory wing mounts: The mounting point, with nipple and body clip, is tucked in behind the shock tower where the air flow is already turbulent. This gives clean air in the center of the wing = more effective.
