We present new gravitational lensing models for giant arcs in the Frontier Fields galaxy clusters, incorporating cluster- and galaxy-scale substructure to improve the model fit. From these models we are able to reconstruct the un-lensed properties of the arcs, including morphology and total luminosity. Combining this information with 2D kinematic data from MUSE spectroscopy, we are further able to construct a high redshift (z > 1) Tully-Fisher (TF) relation, which -- when compared to its lower redshift counterparts -- can be used to probe the evolution of the TF relation over cosmological time.
