IMPORTANT

DO NOT USE A RATTLE GUN OR IMPACT GUN.

If your wheel has raised bumps around the stud holes, you MUST shave 3–4mm from the back of the cap before installation.

Failure to do this may crack the cap.

STEP 1 — CHECK YOUR WHEEL

Some wheels have raised bumps between the stud holes instead of a flat mounting surface.

If your wheel is not completely flat where the cap mounts, the centre cap must be modified before installation.

STEP 2 — MODIFY THE CAP (ONLY IF NEEDED)

Tools Required

Marker
Ruler
File, sandpaper, or grinder

Preparation

1. Turn the cap over and inspect the back
2. Measure and mark a line 3–4mm from the bottom edge
3. Remove material evenly around the cap
4. Continue until the surface is flat and even

Check Fitment

The cap should:

• Sit flat
• Not rock
• Have no visible gaps

If the cap does not sit flat, remove a small amount of material and test again.

STEP 3 — INSTALL THE CAP

Required

60-degree tapered wheel nuts
Wheel brace or ratchet
Torque wrench

Stage 1 — Positioning
Place the cap onto the wheel and hand-tighten the wheel nuts while ensuring the cap remains centred.

Stage 2 — Tightening
Tighten the wheel nuts evenly using a star (cross) pattern.

Stage 3 — Final Torque
Torque all wheel nuts to your vehicle manufacturer’s specifications using a torque wrench.

TROUBLESHOOTING

Issue	Solution
Cap flexing during tightening	Stop immediately, loosen all nuts, re-centre the cap, and tighten evenly again.
Cap still moves after tightening	Install skull cap rubber gaskets to improve clamping pressure and remove movement. VIEW RUBBER GASKETS
Cap does not sit flat	Remove additional material from the back of the cap and test fit again.

IMPORTANT NOTES

• Re-tighten wheel nuts after the first 100km
• Periodically check wheel nut tightness during regular maintenance
• If something does not feel correct during installation, stop and inspect before continuing
