I will present a toy inflating five-dimensional brane-world model with violation of four-dimensional Lorentz invariance. I will discuss possible effects of Lorentz violation on the generation of cosmological perturbations in this model and will demonstrate that at some range of the parameters the spectrum deviates, possibly strongly, from the flat spectrum even for pure de Sitter inflation.
