Subaru Impreza WRX Type R STi Ver.VI

The last version of the GC WRX was introduced in September 1999. There is no change in the mechanical specifications. Added features are newly designed alloy wheels, color-coded mirrors and door handles, remote central locking, intermittent wipers with a timer and map lights.

The European GT model received further upgrades in the form of more parts from the STI range. The front brakes became Subaru branded four-pot calipers with 294 mm (11.6 in) discs, the wheels having become 16-inch lightweight alloys. The STI 4 high-level wing was fitted to the sedan, and STI-style front bucket seats and firmer suspension were also fitted. The "Phase 2" engine now fitted developed 160 kW (218 PS; 215 bhp), an increase of 5 kW (7 PS; 7 bhp) over the previous model.

To counter the grey imports of high-performance Japanese variants, Subaru UK commissioned Prodrive to produce a limited edition of 1,000 two-door cars in Sonic Blue, called the WRX "P1". Released in March 2000, they were taken from the STI Type R lines and used for the P1. The car was the only coupe version of the WRX STI GC chassis to receive ABS. In order to allow for ABS, the DCCD was dropped. Engine output was boosted to 276 bhp (206 kW; 280 PS), and the suspension optimised for British roads. Options were available from Subaru consisting of four-piston front brake calipers, electric Recaro seats, 18-inch wheels and a P1 stamped backbox. The P1, or Prodrive One, is echoed in the name of the Prodrive P2 concept car.
