  With the prospect of improved Higgs measurements at the LHC and at proposed
future colliders such as ILC, CLIC and TLEP we study the non-custodial
Randall-Sundrum model with bulk SM fields and compare brane and bulk Higgs
scenarios. We compute the electroweak precision observables and argue that
incalculable contributions to these, in the form of higher dimensional
operators, could have a non-negligable impact. This could potentially reduce
the bound on the lowest Kaluza-Klein gauge boson masses to the 5 TeV range,
making these states detectable at the LHC. In a second part, we compute the
misalignment between fermion masses and Yukawa couplings caused by vector-like
Kaluza-Klein fermions. The deviation of the top Yukawa can easily reach 10%,
making it observable at the high-luminosity LHC. Corrections to the bottom and
tau Yukawa couplings can be at the percent level and detectable at ILC, CLIC or
TLEP.
