Choosing the correct wheel size and fitment is important for both performance and appearance. Use this measurement guide to help determine the right specifications for your vehicle. If you’re unsure, we offer free fitment advice—simply contact us before placing your order.

Our fitment guide can be found here

Diameter (Inches)
The overall size of the wheel. Common diameters include 18”, 19” and 20”. Larger diameters fill the guards more and change the overall stance, while smaller diameters offer more tyre sidewall for comfort.

Width (Inches)
How wide the wheel is from inner to outer barrel (e.g., 9.5J). Wider wheels provide more grip and a wider stance but require correct offset to avoid rubbing.

Offset (ET)
How far the wheel face sits in or out relative to the hub.
• Higher offset (ET35–ET45): wheel sits further inside
• Lower offset (ET20–ET30): wheel sits further out
Offset affects brake clearance, poke, stance and fitment. If you’re unsure, contact us for recommendations.

Bolt Pattern (PCD)
The stud pattern of your vehicle (e.g., 5x114.3, 5x120). Your wheels must match this exactly. We can machine almost any PCD to suit your vehicle.

Centre Bore
The size of the centre hole that fits over the vehicle’s hub. We machine your wheels to your exact centre bore for a perfect hub-centric fit.

Tyre Fitment
Choosing the correct tyre size prevents rubbing and ensures proper load rating. We can advise on whether to use:
• Standard fitment
• Slight stretch
• Aggressive fitment
• Widebody fitment

Brake Clearance
Big brake kits require specific spoke designs and offsets. If you have Brembos or aftermarket brakes, let us know so we can ensure proper clearance.

If you’re unsure about any measurement, we can recommend the best wheel specs for your vehicle based on your goals, suspension setup and intended appearance.
