My .02 here is find avenues where you can enjoy your car, where you can throw your car around in a controlled setting like autox. Try it with your stock set up, learn from it like how to handle your car, how it reacts, like what they say the best mod you can do is the driver. Then you can opt to do some suspension work... So when the day comes for you to buy your wrx or sti you will be somewhat a step ahead....
