  We study the effect of bulk fermions on electroweak precision observables in
a recently proposed model with warped extra dimensions and no custodial
symmetry. We find that the top-quark mass, together with the corrections to the
Zbb vertex and the one-loop contribution to the T parameter, which is finite,
impose important constraints that single out a well defined region of parameter
space. New massive vector bosons can be as light as 1.5 TeV and have large
couplings to the t_R quark, and suppressed couplings to the t_L, b_L and
lighter quarks. We discuss the implications for searches of models with warped
extra dimensions at the LHC.
