How to Measure for the Perfect Wheel Setup

To get the perfect wheel setup you need two things: your current wheel specs and a measurement of how much space you have left inside the arch. Once you have those numbers, we can build forged wheels to your OEM spec or push them outwards for a flush or aggressive fit — just like running a spacer, but without stacking hardware.

1. Gather your wheel info

• Wheel width (inches)
• Offset / ET
• Tyre size
• Spacer size (if fitted)

Offset is usually stamped inside the wheel. Lower ET sits further out. Higher ET sits further in.

2. Measure your outward clearance

Use masking tape and string to create a vertical reference line down from the arch lip. This tells you how much room you have to push the wheel outward.

• Hold the tape measure at the tyre’s widest point
• Measure to the string — this number = remaining space

If you measure 15mm, you can:

• Run a 15mm spacer
• Drop offset by 15mm
• Order forged wheels 15mm more aggressive

Leave 3–5mm if the car is daily-driven to allow for tyre flex.

3. Running wider wheels?

Wider wheels grow inward and outward, so check clearance to suspension too — not just the arch.

You can increase wheel width and reduce offset so inner clearance remains the same. The extra width then moves outward, closer to the arch instead of the strut.

Example: +25mm wheel width → reduce offset ~12–13mm → inner clearance unchanged, remainder pushes outward.

We build forged wheels to your measurements so you don’t need to guess or rely on spacers.

What affects fitment?

Still unsure what will fit?

Check wheel specs used by others with your car — Facebook forums are useful for this. Just make sure their car isn’t running extra camber, different suspension or a stretched tyre, as those change results.

Once you have a target spec, we can manufacture forged wheels tailored to your measurements — mild, flush or aggressive.
