Alright. Before this gets to about 5 pages of guessing. Here she is.

2001 Corvette Grand Sport. 60k ish miles.
And the reason I said over 400hp is because it has had head work done to it. As well as headers.
My plan of attack. .
-Powder coat these wheels black.
-Eibach Pro Kit (1-2" drop)
-RK Sport Rear Spoiler
-LED Tail Lights (smoked)
-HID Headlight conversion (If possible. . need to do some research)
-Smoked/led parking lights
-Possibly darker windows
Those are the mods I have in mind right off the back after looking at some accessories for the car. The inside has a yellow shift knob and boot. Those will go. Going all black interior. The door sills are a chrome with black circles. I am not feeling those. Going back with some stock black ones. The gauges are aftermarket white ones. Not a fan of that either. Going with some new black gauges. Not factory. But something sexy. no power mods since those have already been taken care of. the seats are a little bit worn. Maybe some brand new stock seat covers later on. Those are expensive. Should look very mean once its done.
