We fitted a full Maxton Design body kit to this BMW 330i, which included a front splitter, side skirts, rear quarter skirts, and a rear diffuser. The kit was installed using a combination of self-tapping screws and silicone for a secure, durable fit. Once fitted, we pressure-tested the kit to check its strength — it held firm and lined up perfectly with the bodywork, following the factory lines seamlessly.The BMW M4 came in with visible damage to its rear diffuser after a minor impact. We removed the damaged section, inspected the mounting points for any underlying issues, and fitted a brand-new OEM-style diffuser. The new unit restored the M4’s aggressive rear profile and factory-fresh finish — ready to hit the road looking as sharp as it should🚘 Audi Q3 2.0 TDI | Stage 1 Performance Calibration ⚙️

This Q3 came in for a performance boost and a full diagnostic inspection before mapping.
No engine codes were found, but the vehicle showed signs of a sticky EGR valve and is due an oil and filter service — something we always highlight during tuning.

We applied a Stage 1 performance remap via OBD, safely verified and tested.
The result? Sharper throttle response, smoother acceleration, and stronger torque delivery across the rev range.

140 → 185 BHP
320 → 410 Nm (+45 BHP / +90 Nm)

✅ No engine DTCs
✅ Smooth idle and consistent boost response
