SPL Parts Rear Upper Lateral Links

2020–2023 Toyota GR Supra & 2019+ BMW Z4

SPL RUA G29

Overview:

The SPL Parts Rear Upper Lateral Links are precision-engineered suspension components designed specifically for the Toyota GR Supra (2020–2023, A90) and BMW Z4 (2019+, G29). These adjustable rear upper arms significantly expand the range of camber adjustment, making them essential for high-performance track and street applications, especially on lowered vehicles. By replacing the OEM links, they allow you to achieve proper rear camber alignment that the factory eccentric washers cannot provide, ensuring optimal tire contact and handling balance.

Ideal for enthusiasts seeking improved rear suspension geometry, these links enhance vehicle stability under aggressive cornering, acceleration, and braking. They deliver a direct, responsive feel by eliminating the compliance and deflection common in stock rubber bushings.

Key Features:

Engineered for strength, precision, and ease of use, the SPL Parts Rear Upper Lateral Links offer the following benefits:

• Extensive camber adjustment range beyond OEM capabilities for precise alignment
• Gun drilled 2024 aluminum center links, clamps, and clevises for lightweight durability
• Blue anodized titanium socket head cap screws for corrosion resistance and strength
• 360-degree rotating clamp system enabling quick, accurate adjustments without disturbing bearing orientation
• FK spherical rod ends with Teflon-lined PTFE bearings for smooth articulation and reduced friction
• Elimination of soft, worn-out OEM bushings to minimize suspension deflection under load
• High load capacity and excellent dynamic wear resistance for long-lasting performance
• Simple locking mechanism using a 3/16" Allen key for hassle-free alignment maintenance
• Wide operating temperature range from -65º to high heat environments, ensuring reliability in all conditions
• Proudly designed, engineered, and assembled in the USA

Construction & Design:

The Rear Upper Lateral Links are crafted from premium 2024 aluminum, chosen for its exceptional strength-to-weight ratio and resistance to fatigue. The components are meticulously gun drilled to reduce weight without compromising structural integrity. The use of blue anodized titanium hardware not only enhances corrosion resistance but also adds a sleek, durable finish.

The innovative 360-degree rotating clamp system allows the spherical rod ends to be precisely oriented and securely locked in place with minimal effort. FK spherical rod ends incorporate a chemically bonded PTFE liner that provides quiet operation, low friction, and smooth articulation while eliminating bushing deflection under high loads. This design ensures consistent suspension geometry and improved handling precision.

Installation & Fitment:

These Rear Upper Lateral Links are direct-fit replacements for the Toyota GR Supra (2020–2023) and BMW Z4 (2019+), requiring no modifications to the vehicle’s suspension. Installation is straightforward for experienced enthusiasts or professional mechanics, with all necessary hardware included. The adjustable design allows for fine-tuning camber settings to meet specific alignment requirements, particularly beneficial for lowered cars that exceed OEM adjustment limits.

What's Included:

• Rear Upper Lateral Links (left and right)
