Lorentz violating effects would manifest themselves in gravitational waves travelling with a greater speed in the bulk than on the brane and this effect is independent of the signature of the extra dimension.8 pages, to appear in PLBGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
