For those who have already modified their Mk2 Focus ST or RS models with basic bolt-on modifications and now want to take it up a level, we offer a series of well proven, drive-in, drive-out, big power packages; the DD500, DD600 and DD700 builds.
We have developed each of these comprehensive packages carefully over time to ensure reliable, effective and usable power, thanks largely to an improved torque biasing traction control system included in the package for all our 500+bhp builds.
