Overview:

The Superpro Front Lower Inner Control Arm with Caster Bushing Kit is a precision-engineered suspension upgrade designed specifically for the Subaru BRZ (2013–2024), Toyota 86 (2017–2020), and Toyota GR86 (2022–2023). This component plays a critical role in the vehicle’s front suspension system by providing a durable pivot point that enhances handling dynamics and steering response. Ideal for enthusiasts seeking improved road feel and cornering performance, this control arm kit introduces an offset bushing that adds positive caster to the front suspension geometry, delivering tangible benefits without compromising ride comfort or tire wear.

Whether you are upgrading your vehicle for spirited street driving or track use, the Superpro control arm offers a reliable and performance-focused solution that enhances stability, steering precision, and overall driving confidence.

Key Features:

Superpro’s Front Lower Inner Control Arm with Caster Bushing Kit incorporates advanced design elements and materials to improve suspension performance. Key features include:

  • Offset polyurethane bushings that increase positive caster for enhanced straight-line stability and improved tracking.
  • Dynamic camber gain during steering, allowing tires to maintain optimal contact patch through corners for better grip and control.
  • Improved steering weight and feedback, providing a more connected and responsive driving experience.
  • Polyurethane construction that outperforms traditional rubber bushings in durability and longevity.
  • Maintains OEM levels of noise, vibration, and harshness (NVH) isolation for a comfortable ride.
  • Resistant to extreme temperatures, oils, water, and coolant, ensuring reliable performance in all conditions.
  • Designed and manufactured in Australia with nearly five decades of suspension expertise.
  • Lifetime warranty for peace of mind and long-term reliability.

Construction & Design:

The control arm features Superpro’s proprietary engineering-grade polyurethane bushings, which provide superior strength and resilience compared to standard rubber components. This material choice ensures that the bushings maintain their shape and performance characteristics even under harsh driving conditions and exposure to environmental contaminants. The offset design of the bushings is carefully calibrated to add positive caster without introducing adverse effects such as increased tire wear or compromised ride quality.

Manufactured with precision and durability in mind, the control arm assembly is built to withstand the rigors of both daily driving and aggressive cornering, making it a dependable upgrade for performance enthusiasts.

Performance & Sound

By increasing positive caster, this control arm kit enhances straight-line stability and steering return-to-center behavior, reducing driver effort during highway cruising. The dynamic camber gain improves tire contact during cornering, resulting in better grip and reduced tire shoulder wear. Additionally, the enhanced steering weight and feedback provide a more engaging and predictable driving experience without introducing unwanted noise or harshness.

This Superpro Front Lower Inner Control Arm is a direct fit replacement for the specified Subaru BRZ, Toyota 86, and Toyota GR86 models. Installation requires standard suspension tools and basic mechanical knowledge. No modifications to the vehicle’s chassis or suspension geometry are necessary, as the offset bushings are designed to bolt directly into the OEM mounting points. Proper alignment after installation is recommended to maximize the benefits of the added caster angle.

What's Included:

  • Front Lower Inner Control Arm assembly
  • Offset polyurethane caster bushing kit
  • Installation hardware as required
