OP, try rallyx and enter SA (stock AWD) class.
You will gain new appreciation for driving control. A few years ago some dude used to do well in his class with a POS stock Altima automatic with regular stock like tires. Rallyx has taught me how to "have fun" with a fricken van and a Toyota Yaris. By "fun" I don't mean "fast"; I mean the challenge of driving consistently within set limits, a lot of similarities to momentum driving. I realized long ago that the secret to going fast when you actually do have a performance car is still about being able to consistently drive up to a limit; whether or not that limit is an actual physical limit (like at the track) or artificial limit (like 5/10ths). When you can get consistent with control like this, you end up being fast when you actually get to drive a performance car in the proper venue (ie track).
That being said, maybe you should put stiffer springs and better tires on your Impreza... makes a huge "feel" difference.
