420motorsport. Wheel Center Caps & Hubcaps

What a center cap does on the wheel

A center cap sits in the wheel's center bore and covers the hub. It gives the wheel a finished look and, depending on the design, can shield the hub area from dirt and water. Among our wheel center caps you will find, for example, the BBS Center Cap in 56 and 70 mm, the Advan 73mm Flat Center Cap and caps from Gram Lights and SSR. Many caps are made for specific wheel models and therefore belong with wheels from the same brand. The category also includes brands such as Method Wheels, Kansei and Raceline.

How to choose the right center cap

Fitment matters more than looks. Check these points against your wheel:

Diameter: Caps are typically specified in millimetres, e.g. 56, 70 or 73 mm, and must match the wheel's center bore or holder.

Wheel model and size: Some caps are tied to specific wheels, e.g. the SSR MKII Center Cap for 13, 14 and 15-inch wheels with PCD 100-101.65.

Attachment: The number of retaining tabs, e.g. a 4-tab design, must match the wheel's mounting points.

Shape and colour: Flat and low caps such as Advan Full Flat or ICON Alpha Low Pro give a more discreet look, while options like black/gold, blue anodised or 3D logo can be matched to the wheel's finish.

Installation and care

Clean the center bore before installation and press the cap evenly into place so that all retaining tabs engage. If a cap sits crooked or loose, it can fall off while driving. Depending on the wheel, the cap may need to come off before you can reach the lug nuts and lug bolts. Wash the caps with mild soap, and be careful with strong wheel cleaners on anodised and chrome-plated surfaces. Other parts for your wheels can be found under tyre and wheel accessories.

Frequently asked questions

Does a center cap from one wheel brand fit another wheel?

Typically not without further ado. Diameter, retaining tabs and shape are often adapted to specific wheel models. Compare the cap's dimensions and the stated wheel model with your wheel before ordering.

How do I find the right center cap size?

Measure the diameter of the wheel's center bore or the old cap in millimetres, and count the retaining tabs. If the product name includes a wheel designation, e.g. 57CR / 57DR, you can use it to check that the cap fits.

Why does a center cap fall off while driving?

It is often caused by broken or worn retaining tabs, the wrong diameter or dirt in the center bore. Check the cap and the center bore, and replace a damaged cap instead of refitting it.

How do I clean center caps without damaging the surface?

Use mild soap and a soft brush. Strong acid- or alkaline-based wheel cleaners can dull or discolour anodised, chrome-plated and painted caps, so read the cleaner's instructions first.
