Maserati GranTurismo & Quattroporte Wheel Spacers (5×114.3) – Precision CNC Machined

Brightstone Engineering’s Maserati hubcentric wheel spacers are engineered for all 5×114.3 Maserati models including the GranTurismo M139, GranTurismo MC/M145 Facelift, and Quattroporte M139 & M156. Each spacer uses the correct 67.1 mm hub bore and 5×114.3 PCD for a perfect OEM-grade fit.

By widening the vehicle’s track width, these lightweight billet aluminium spacers improve cornering grip, stability and steering response, while giving your Maserati a more aggressive and purposeful stance. Ideal for both road and performance applications.

Every spacer is CNC machined in the UK from aerospace-grade 6082-T6 aluminium and finished in a deep black anodised coating for long-term corrosion protection. Each kit includes extended M14 × 1.5 high-tensile bolts matched to factory specifications for Quattroporte and GranTurismo models.

Whether you are enhancing stance, fitting wider tyres, or creating clearance for brake upgrades, our Maserati 5×114.3 spacers provide the perfect blend of precision, performance and UK-made engineering.
