Nice looking car, I like it a lot better than the current/now soon to be previous version. I owned a '90 GS-T from new back when they came out and it was fun.
From that nice pic, I would have to lower the car to reduce that huge gap between the top of the tires and the wheel arch. Of course you could do that with lowering springs and suffer ride comfort, or go with adjustable coilovers at much greater expense. The wheels look OK, but to make it personal and more unique, I always like a nice aftermarket wheel. If you are not going to seriously hammer on the car on a road course, I would stay away from aftermarket brakes for a while till you feel out what you have. The brakes are adequate for normal applications. While some like the looks of drilled rotors, they are notorious for cracking when used hard.
When the warranty runs out, hopefully by then somebody will have a turbo or supercharger kit developed for this car
