need traction help

Ok,
I have a 1998 z28 convertible with an ls6 conversion (heads, intake, cam) kook long tube headers, ARE reduction pully, Magnaflow cat back, and an SLP lid with a K&N filter, and an LS1 edit tune.
My question for you guys is this; How do I put my power to the ground?
I have 16" wheels and tires now and when the tires wear out I am going to replace them with 17" wheels and tires. I am looking for the most cost effective way to get the tires to hook up. I also don't want my car to look fast. I just want it to be fast.
Thanks in advance for any suggestions.

well, drag radials are the first step seeing as you are buying tires anyway. next up would be the trailing arms, relocation brackets, panhard rod, shocks, to start off with.
