Fitment Guide
Correct fitment is not optional. A part that does not fit precisely is not a part — it is a liability. This guide explains how to verify compatibility before you order, and what to do if you are unsure.
Wheels
To confirm wheel fitment, you need four measurements:
-
Bolt Pattern (PCD) — The number of bolts and the diameter of the circle they sit on. Example: 5x112 means 5 bolts on a 112mm circle. This is non-negotiable — it must match exactly.
-
Offset (ET) — The distance in millimetres between the wheel's centreline and its mounting face. A higher ET pushes the wheel inward; a lower ET pushes it outward. Incorrect offset affects handling and can cause rubbing.
-
Hub Bore — The diameter of the centre hole. The wheel's hub bore must be equal to or larger than your vehicle's hub diameter. If larger, a hub ring is required.
-
Width and Diameter — Confirm that the tyre size and wheel diameter are compatible with your vehicle's arch clearance and brake caliper clearance.
Body Kits & Aero Parts
Aero components are chassis-specific. Before ordering, confirm:
- Your exact chassis code (e.g. F30, B9, W205)
- Your bumper variant (M Sport, AMG Line, S-Line, standard)
- Whether your vehicle has parking sensors and their configuration
- Whether your vehicle has adaptive cruise control or front radar
Many aero parts require professional installation and may need modification for sensor integration. This is noted on individual product pages where applicable.
Floating Centre Caps
Floating centre caps are fitment-specific by centre cap diameter and spigot size. Confirm the outer diameter of your existing centre cap and the spigot diameter of your wheel hub before ordering.
Still Unsure?
