what is the slip diferential on the 04 as far as front to back and left to right if any one knows. And is there anything you can do to or about the traction control to bring more power to the rear rather than the front...for more of a drift effect kkkkkep rokin
The WRX 5 speed has a viscous type center and rear differential. The front diff is open. There are no adjustments for it. If you want an adjustable center diff to send more power to the rear you will need to get an STi or install the STi tranny into your WRX (expensive). The DCCD in the STi tranny allows you to change the power split with a knob on the center console.
