First off, I drive a wrx
.
If you want a car to make all out power, the STi is the wrong car. It isnt meant to make massive power like a Cobra is. I think that is pretty obvious from just looking at the engine choices. That being said, I think comparing the two cars is a valid thing to do, they cost relatively close to each other, and have similar performance stock v stock. Staying strictly stock, the STi is the winner in performace per $. However when we start talking about modding, the Cobra is the obvious winner, as you can do pretty much anything and everything that you can think of to a Mustang.

That’s the only answer your gonna get here, I mean what do you honestly expect. But why? For me there are 3 main reasons: 1) i would rather put the power to 2 sticky 315s in the rear than 4 215s any day. Over steer is more fun for me, and I prefer the higher cornering threshold. 2) Its a 4 door... that’s all i have to say (not performance related but when is the last time you took 3 friend for a lap around willow spring?) 3) Power, I don't care how well a wrx handles, it will not make up for the 100hp/tq deficit in anything faster than an auto-x.
