Uhh... Have you ever modded a car before? Do you not care about money? Do you have preferences? What are you trying to acquire? You are leaving a very vague request here. You can always build your own kit rather than paying a high priced kit that is put together for you.
Step 1 - Lower it
Step 2 - Do some research.... APR stage 3 is nice but also $$$
Step 3 - Learn how to type in sentence form ok so you dont continually run on and confuse everyone while you ask questions
how long you plan keeping the car? do you plan to race, pink slips, track the car, autocross?
if you do a stage 3 def do a lmtd. slip.diff, n def a big brake kit so u cant stop as well, jus as important.
