The G54 15 mm Billet Wheel Spacers for 4 x 100 PCD applications provide a useful middle ground between subtle fitment correction and a noticeably wider wheel stance.
With a thickness of 15 mm, each spacer moves the wheel 15 mm further out from the hub. This gives a more visible change in wheel position, helping reduce the recessed appearance often seen with factory wheel offsets and creating a stronger relationship between the wheels and bodywork.
The spacer uses a 4 x 100 PCD, meaning four wheel bolt positions are arranged on a 100 mm diameter circle. PCD stands for Pitch Circle Diameter and is the measurement used to identify the wheel bolt pattern.
G54 manufactures the spacer from billet 6082 aluminium, chosen for its high strength to weight ratio and suitability for precision machining. Extensive pocketing removes unnecessary material from the component while maintaining structural integrity.
This focus on weight is deliberate. A wheel spacer adds mass directly to the rotating wheel assembly, so minimising that mass helps preserve suspension response, steering behaviour and acceleration.
The hub centric centre bore provides accurate and secure location against the hub, helping the wheel remain correctly centred after the spacer is fitted. Tapered wheel bolt holes make bolt alignment easier, particularly when supporting the weight of the wheel during installation.
G54 has also machined access pockets into the side of the spacer. These provide a practical point for easing the spacer away from the hub after extended use, avoiding the frustration commonly associated with basic flat sided spacers.
An anodised finish protects the aluminium against corrosion and contributes to long term appearance.
For enthusiasts searching for 15 mm wheel spacers with a 4 x 100 bolt pattern, this G54 option combines improved stance, greater inner clearance and a wider track with carefully considered lightweight engineering.
