2013–2020 Subaru BRZ / 2017–2020 Toyota 86 / 2022–2024 Toyota GR86
KCA435
Overview:
The Whiteline Roll Center Adjuster Kit & Bump Steer Correction is an essential upgrade for owners of lowered Subaru BRZ, Toyota 86, and Toyota GR86 models. Designed to address the common suspension geometry issues that arise when lowering these vehicles, this kit corrects roll center height and bump steer for improved handling precision. By raising the front roll center, the kit enhances front roll resistance and reduces suspension compression on the outside front wheel during cornering. This leads to more balanced weight distribution, better tire contact with the road, and ultimately increased front-end grip and cornering performance.
Ideal for enthusiasts who demand sharper steering response and improved vehicle dynamics, this Whiteline kit optimizes suspension geometry to reduce understeer or oversteer tendencies, making it a must-have for track days, spirited driving, or any lowered setup.
Key Features:
This roll center and bump steer correction kit incorporates advanced engineering and durable materials to deliver tangible handling benefits:
- Specifically engineered ball joints and tie rod ends designed to correct roll center geometry
- Raises front roll center to increase roll resistance and reduce outside wheel suspension compression
- Improves tire contact patch for enhanced front-end grip and cornering speeds
- Optimizes toe alignment to reduce uneven tire wear and correct inherent understeer or oversteer
- Protective E-Coat finish provides superior corrosion resistance and durability in harsh conditions
- Includes detailed installation guide for straightforward fitting
- Precision-engineered to maintain factory suspension travel and ride quality
- Compatible with lowered suspension setups without compromising safety or performance
Construction & Design:
The Whiteline Roll Center Adjuster Kit is crafted from high-strength materials engineered to withstand the rigors of aggressive driving and track use. The components feature a robust E-Coat protective coating, which forms a hard, corrosion-resistant skin far tougher than conventional paint finishes. This ensures long-lasting durability even in wet or salty environments.
Each ball joint and tie rod end is precision-machined to exact tolerances, ensuring seamless integration with the vehicle’s suspension system. The design focuses on maintaining optimal suspension geometry while allowing for the necessary adjustments to roll center height and toe alignment, resulting in improved handling without sacrificing ride comfort.
Installation & Fitment:
The kit is designed for direct fitment on the following vehicles: Subaru BRZ (2013–2020), Toyota 86 (2017–2020), and Toyota GR86 (2022–2024). Installation requires moderate mechanical skill and basic tools. Whiteline includes a comprehensive installation guide with step-by-step instructions to assist with proper setup and adjustment.
No major modifications to the vehicle’s suspension are necessary, making this kit an accessible upgrade for enthusiasts looking to enhance handling characteristics on lowered cars. Proper alignment after installation is recommended to maximize the benefits of the roll center and bump steer corrections.
