  We present distance estimates for eleven peculiar Virgo cluster spiral
galaxies based on measurements of the stellar kinematics of their central 2
kpc. Stellar circular velocities were obtained using two-integral dynamical
models. Distances were obtained by comparing, at each radius, the stellar
circular velocities with synthetic H_alpha rotation curves derived from NIR
Tully-Fisher relations.The results show that most of our galaxies are located
within 4 Mpc of the core of the cluster. Three of these galaxies, previously
classified as "low rotator galaxies" or with "Truncated/Compact" H_alpha radial
distributions, have stellar kinematics-based distances that are discrepant with
HI-based distances by at least 60%, and are likely to be located within the
virial radius of the cluster. These discrepancies appear due to very truncated
gas distributions plus non-circular gas motions or gas motions not in the plane
of the stellar disk, perhaps as the result of gravitational interactions. Our
results show that environmental effects can significantly reduce the measured
HI linewidths for some disturbed cluster galaxies, thus affecting the accurate
determination of distances based on gas kinematics methods.
