Focus ST225 / XR5 Turbo

400bhp from a Focus ST225. The 2.5 five-cylinder, finally let off the leash.
The ST225 came of age years ago. Buying one of these brilliant 2.5-litre five-cylinder cars is now easily affordable and the number being tuned grows by the day. Since the ST Mk2/XR5 launched in 2005 we have been big fans of the car, of the sound and, most of all, of how it responds to tuning.
Stage 1 to the mighty Stage 4, fitted in-house or shipped worldwide
We have seen and tuned an extremely high number of these cars over the years. Stage 1, Stage 2, Stage 3 and the mighty Stage 4 packages have all been fitted in our workshop and sent out by mail order across the world.
