’05 Impreza WRX STi Type-UK In Detail

Sure to appeal to enthusiasts, a driver’s control centre differential (DCCD) becomes standard on the WRX STi.

The DCCD is operated via a switch mounted next to the handbrake and allows the driver to manually select the torque distribution front to rear, reverting to automatic mode every time the ignition is turned off.

For example, he or she can choose between having a sharper cornering turn-in or more stable straight-line running.

However, on the new 2005 Impreza WRX STi, the system is further upgraded by the fitment of a yaw-rate sensor and new front helical limited-slip differential.

The new front LSD is quicker-acting than the previous type and improves steering stability when cornering near the limit. It also improves the car’s steering behaviour on slippery surfaces with less side-to-side tug.

Meanwhile, the yaw rate sensor enhances the balance between straight-line stability and turn-in.

The car, of course, continues to employ Subaru’s much-admired symmetrical, full-time all-wheel drive system with a rear LSD.
