I got a novistretch bra and it worked well for a while. Then I did a 3000 mile trip and it stretched too much on the sides causing to rub against the paint and leave marks. You can see it in my sig pic how it scrunches up on the corners near the wheels. At low speeds it probably would've been fine. But once you have some speed, air will get in there and make the material move around.
That being said I was sure glad to have it on that trip. It prevented a lot of crap from getting stuck in my radiator. The scuffs it left i was able to remove. In the future I'll probably move the velcro in the wheel well to keep the material from scrunching up like it did.
