you paid money for lowering bolts? you can get the car so low on stock bolts and cutting one rib off the bushing that you scrape almost everything, dead animals, bumps on the freeway, you name it. HPfiend got one a few months ago and my car side by side his is almost 4" lower.
good call on the intake, i love mine. the headslamps need HID's though, they suck. there is a kit on corvetteforum for under $300 and they are awesome.
good call on the car, your going to love it.
