Nice car Amber. I actually like the Rims. I strongly suggest going with the D1SC from Pro-Charger. You will blow your BFs car away without a problem if you can keep the wheels from spinning through the first 4 gears.
I have an 01 Z06. We put the D1SC on it. Upgraded to full length headers, removed one set of cats and upgraded the fuel injectors and fuel pump. With custom tuning I am making 680 HP at the flywheel (579 RWHP). The best part is its just as good driving around town as it is when getting on it.
You could still spray on top of the super charger as well. They have full kits for that. Just make sure you tuner knows what that they are doing
A couple of pics.
Dyno supercharge vs. the stock pull
Remember the wave.
