Just installed them this week, did pad bedding yesterday. Brake feel isn't really changed compared to stock, or at least not in a way that is super noticeable like you'd get with dedicated track pads.
Car feels better overall due to the reduced unsprung weight and maybe a bit better accel. Dust wise, we'll have to see but yes in general I would expect far far less dust.
Took off the wheels and cleaned the inner barrels and gave them a good scrub (though once dry it was clear i need to touch up some spots) and we'll see, but I expect I'll effectively not really need to clean them again beyond spraying them down when I wash the car.
