Love the faux-Sube WRX STI black headlights, roof hood scoop, mudflaps and even the blue & yellow livery. No big wing. The cage looks very sturdy but makes any 'open' airflow, very dirty. Still recommend a clean 'closed' sedan.
A large front dam is a good start. (Getting a cheap used SRT front clip?).
Many ecomodders here, have already done this DIY. Home Depot deep front/side skirts, with garden edging.

Coroplast panels (used political signs) for sealing any/all openings.
If you got any sheckels, fabrication skills & ambition left, a DIY 'fastback'.
