FRS BRZ GT86 GR86 Adjustable Front LCA

Just Engineering Adjustable Front Lower Control Arms - FRS / BRZ / GT86 / GR86

Engineered specifically for the rigors of lapping and road racing, the Just Engineering Adjustable Front Lower Control Arms (LCAs) are the ultimate suspension upgrade for the ZN6 and ZN8 platforms. These arms utilize a laser-cut steel construction designed to maximize structural integrity while maintaining the original arm’s clearance—a feat of engineering that balances strength and weight better than any other design on the market.

Built for maximum rigidity and durability, each arm features a 4130 billet bearing cup at the ball joint to ensure reliability under extreme cornering loads. Beyond simple adjustment, these arms feature an in-house ball joint assembly that corrects the lateral roll center, restoring proper suspension geometry on lowered vehicles for significantly improved handling and predictable feedback.

Key Features

• Advanced Construction: Laser-cut steel design provides superior strength-to-weight ratios while maintaining critical clearance.
• Roll Center Correction: Integrated ball joint assembly corrects lateral roll center to optimize geometry on lowered cars.
• Full Adjustability: Fine-tune your alignment with adjustable camber and caster settings for track-specific performance.
• Anti-Dive & Bump Steer: Includes integrated bump steer correction and spacers to allow for adjustable anti-dive geometry.
• Premium Components: Features high-load rated chromoly spherical bearings, forged chromoly rod ends, and a 4130 billet bearing cup.
• High-Grade Hardware: Assembled with custom machined chromoly adjusters and high-grade hardware throughout for maximum longevity.
