SPL Parts Non-Adjustable Front Caster Rod Bushings

Fitment: 2014-2023 BMW M3 (F80)

Part #: SPL CRBN E9X

Overview

The SPL Parts FKS Series Non-Adjustable Front Caster Rod Bushings are high-performance suspension components designed specifically for the BMW M3 (F80) from 2014 to 2023. These bushings replace the stock rubber bushings with low-friction, articulating spherical bearings, providing a significant upgrade in suspension response and handling precision. Ideal for enthusiasts seeking improved steering feel, reduced bushing deflection, and enhanced feedback during aggressive driving or track days, these bushings help maintain optimal suspension geometry under load, contributing to more predictable and confident vehicle behavior. Crafted for durability and performance, they are an excellent choice for drivers aiming to elevate their M3’s handling capabilities.

Key Features

Designed with performance in mind, these bushings feature massive 1" FK Racing Bearings with self-lubricating Teflon liners, ensuring long-lasting smooth operation and resistance to wear. The use of high-quality materials and precision machining results in a product that supports consistent suspension geometry and reduces unwanted deflection. The spherical bearing design eliminates the flexibility of rubber bushings, providing a more direct connection between the suspension components and the chassis. This translates into sharper steering response, improved feedback, and enhanced overall handling dynamics. Made in the USA, these bushings are built to withstand demanding driving conditions and provide reliable performance over time.

Construction & Design

The bushings are constructed using durable materials with a focus on structural integrity and friction reduction. The spherical bearings are engineered to articulate smoothly, supporting precise movement and load transfer. The design ensures minimal deflection and maintains suspension alignment, even under aggressive driving loads.

Installation & Fitment

Installation involves replacing the factory bushings with these high-performance spherical bearings, typically requiring standard suspension tools and procedures. Proper fitment should be verified against the vehicle’s specifications and the part number provided.

What’s Included

The package includes the non-adjustable front caster rod bushings with spherical bearings, designed for direct replacement of the stock components. Hardware and additional mounting accessories are not included and should be sourced separately if needed.

Ideal For

This product is ideal for BMW M3 owners looking to improve handling response, steering feedback, and suspension durability. It is well-suited for track enthusiasts, performance drivers, and anyone seeking a more engaged driving experience with their F80 M3.
