Steering Noise Reduction Copper Shims

⚠️ Important Notice
This product is designed specifically for low-speed steering clicking and creaking noises associated with two-piece rotors. It is not a universal solution for all brake noises.

The Problem: Low-Speed Steering Clicking & Creaking on Two-Piece Rotors?

Are you hearing a rhythmic "clicking" or a low "creaking" sound from your front wheels when steering at low speeds? This is a common issue with two-piece rotors — affecting both floating and fixed designs.

The cause? Aluminum rotor hats and steel hubs have different friction properties. Under lateral load during a turn, the interface can micro-slip (clicking) or bind and release (creaking), generating that annoying noise. Our copper shims offer a simple, reversible fix for both.

Specifically Designed for Two-Piece Rotors with Factory Brake Setups

Our shims are engineered to address the exact contact-surface mismatch found in two-piece rotors — regardless of brand, size, floating or fixed. Perfect for vehicles running standard factory brake systems with two-piece rotor upgrades.

• Eliminates Both Clicking & Creaking: Targets the root cause — micro-slip and friction instability at the hub-to-hat interface.
• Designed for Factory Brake Setups: Works with standard calipers and stock brake systems (not limited to BBK).
• Preserve Original Geometry: 0.1/0.15mm thickness won't alter your wheel's offset or brake clearance.
• Reversible & Non-Destructive: No grinding, no drilling – just a simple, removable shim.

How It Works

Place the copper shim between the wheel mounting surface and the rotor hat. The soft copper deforms microscopically under pressure, increasing contact area and friction — stabilizing the interface and eliminating the micro-slip that causes clicking and creaking.

Copper Shim – Quick Guide

What is this for?

Stops clicking or creaking noise from two-piece rotors during low-speed turns.

How it works

Sits between the wheel hub and rotor hat. Stops the metal slip that causes the noise.

Installation

1. Remove wheel
2. Clean the hub mounting face and rotor hat contact surface — remove any rust, dirt, or debris
3. Place the shim onto the hub surface
4. Reinstall the rotor and wheel, torque to spec
