Little update. So it turns out BC does not make coilovers for the model S RWD, only the AWD. All the adds online are incorrect or at least they're not available anymore. This was confirmed by the tuning shop I went to this morning who spoke to BC directly. Good news was they were able to contact D2 racing (I know, confusing with all the acronyms) and they had coilovers made for the RWD model. I ended up placing the order which should take a week so hoping for the install next week. Fyi, D2 is huge in the JDM world because they specialize is air suspension systems.
