Hi my name is Matt and I am new to this site. I am looking into purchasing a new 2010 WRX. I have test driven and researched the car a fair amount, but would like to learn more about them. Does anyone know what the major differences are between the standard and sti models?? I can see the obvious things like the additional 40 hp, and a 6 speed gear box. I like the styling better on the std model, but I am interested in the best possible performance. Is there any mods to get the standard model over 300 hp without voiding my warranty?? I am not a mechanic so my warranty is important to me. Any input that you WRX owners could give me would be much appreciated. Thanks in advance.
