I'm a big fan of aggressive kits when done right with suspension/wheels. I bought my vert with a stock RB20 in it and decided to do body/paint/suspension/brakes before I began going for more power. Now that I'm finishing up with my new turbo setup, the car already has everything I need to put the power to the ground. So no, I don't think there is anything wrong at all with modifying the car in the order you want to.
Look into OEM aero. It has the clean factory look with the durability of urethane, far more resilient than any fiberglass kit
