%X We present the prediction of the electroweak ρ parameter and the W boson mass in the CP-violating Next-to-Minimal Supersymmetric extension of the Standard Model (NMSSM) at the two-loop order. The ρ parameter is calculated at the full one-loop and leading and sub-leading two-loop order <i>O</i>(α+ α<sub>t</sub>α<sub>s</sub> + (α<sub>t</sub>+α<sub>λ</sub>+α<sub>κ</sub>)<sup>2</sup>). The new ∆ρ prediction is incorporated into a prediction of M<sub>W</sub> via a full supersymmetric (SUSY) one-loop calculation of ∆r. Furthermore, we include all known state-of-the-art SM higher-order corrections to ∆r. By comparing results for ∆ρ obtained using on-shell (OS) and ―DR renormalization conditions in the top/stop sector, we find that the scheme uncertainty is reduced at one-loop order by 55
