If you have to save the money to get the good stuff then do it, its well worth it. I like Nuespeed bars.
But I want to agree. Class is the best bet. I want to take one so bad, but I dont have the time or money either right now. So maybe later.
Also, study up, and test settings. Learn what kinda adjusting you can do on your car to make it handle better. I.E. Tire air pressure, suspension damper settings, downforce, etc. All of these things can make a big difference in the way your car handles and are usually cheap to come buy.
