What Stillwater drivers book
The Upgrade Shop is not a tire warehouse and not a dealer quick lane. Stillwater customers come for performance upgrades, general repair, and engine swaps when the local pack will not touch a turbo, a European chassis, or a rebuild.
- Performance upgrades. Turbo, exhaust, suspension, brakes, and ECU work for European, exotic, and seriously built daily drivers.
- General repair. Diagnostics, brakes, suspension, drivetrain, and maintenance for drivers who want the same shop that builds engines.
- Engine swaps and rebuilds. Cylinder head work, complete rebuilds, and engine swaps for cars that deserve more than a used long-block from a catalog.
