  We discuss how the full dynamics of top condensation models can modify the
relations between the physical top mass, the amount of custodial $SU(2)$
violation and the weak gauge boson masses. It is emphasized that it is possible
to get phenomenologically acceptable relations between $\Delta\rho$, $m_t$ and
$M_W$ and that in addition the scale of new physics can be chosen to be ${\cal
O}(TeV)$ such that a fine--tuning problem is avoided.
