Vehicle Details
Make: BMW
Model: M4
Year: 2017
Status: Completed
The Challenge
The vehicle was already extensively modified for track use, but was still running a standard factory engine and driveline. While the car remained drivable, the original unit was not ideally suited to sustained high-performance use. After assessment, an engine replacement was recommended to better support the vehicle’s track-focused setup.
Components we fitted:
Very low-mileage S55B30A engine supplied and fitted
New performance oil filters installed
Fresh BMW M-spec engine oil added
Ancillary components inspected and transferred where required
Engine systems checked and verified after installation
Full testing carried out under operating conditions
The Solution
With the low-mileage BMW M4 engine installed, the vehicle now benefits from improved reliability and performance tailored for track use. Following thorough testing, the car was returned to the owner fully operational and ready for high-demand driving.
