Spend $3,000 on wheels then spend another $3,000 on mods to get back to stock times.
It's not all about quickest times...a lot of mods for the G improve the sound of the car. The PopCharger with a Z-tube and an MREV2 at 6k rpms sounds like mechanical heaven.
And to throw your figures off a little (100-150 per additional HP)...Forced Induction will be about $50 per HP. ($6k for a vortech which will give you about +120HP at the crank)
