Subaru Impreza performance services
Choose upgrades that work as a complete package
MB Developments supplies, installs and develops Subaru Impreza performance upgrades from our specialist workshop in Darlaston, West Midlands. Whether the car is for fast-road, track or competition use, the specification should balance response, reliability, braking, chassis, cooling and engine management rather than chasing one headline figure.

Supply, installation, testing and tuning in one place
Dedicated workshop and engine-building facilities sit alongside our true synchronised 4WD rolling road. That lets us take a project from its initial specification and parts selection through installation, diagnostics and calibration without losing sight of how the individual systems interact.
We also stock genuine Subaru components and performance parts from established manufacturers for owners carrying out their own work.
