Suspension Needs!!

Well I've had my LS1 Z28 for about a month now and i have added cat back and a ypipe but now that its fast and all i need to have better handling.
I am looking at spending up to 500 dollars to get this beast planted around corners. What do you guys reccomend. I was looking at a drop spring kit, sway bars, strut tower brace, and shocks but i dont know which would be the best bet and most worth my time. Thanks for the help

Subframe connectors. Nothing else needs to be said. Makes a huge difference. Tightens up the car and gives it the feel it should have had from the factory. Will run you about $100 plus installation.

When I dropped my car I had excessive body roll, enough that my stock sized tires (245/50/16) would rub my fenders. Nobody that I've talked to ever had this problem. Springs will run you around $200.

A sway bar kit will make a huge difference. Front and back sway bars run around $400 for both I beleive. I don't have sway bars yet, so I'm not sure.

An adjustable panhard rod. Huge improvement over stock handling. This is a must if you want your car to handle well. Will run around $100 or so.

Lower control arms can help with handling depending on what type you get. Can run anywhere around $100-200 for a pair. Relocation brackets aren't necessary, but highly recommended for a lowered car to fix the geometry of the suspension (LCAs should be parallel or pointed slightly downward to the ground).
