more drift or more race build - what do you drive and why?

I tend to run track differential, track suspension, and race tires. It obviously makes a huge difference, where just the components alone will alter your acceleration and max speed by at least 10-20%. On top of that, if you were trying to spec to drift, you would be using a single turbo or any of the superchargers that give greater power output at lower speeds, as opposed to dual turbo on a race spec. Needless to say, it amounts to quite a huge difference, putting aside the fact that a drift spec makes it far more challenging to drive in a straight line :D
