2020–2023 Toyota GR Supra, 2019+ BMW Z4 (G29)

SPL RTA G29

Overview:

The SPL Parts Rear Toe Links are precision-engineered suspension components designed specifically for the 2020 and newer Toyota GR Supra (A90) and the 2019 and newer BMW Z4 (G29). These rear toe arms replace the factory components to provide enhanced stability, sharper response, and a significantly increased range of rear toe adjustment. Ideal for enthusiasts who have lowered their vehicles or require performance-oriented alignment settings, these toe links help maintain optimal tire contact and handling balance under dynamic driving conditions.

By eliminating bushing deflection common in stock rear toe arms, SPL Parts’ design ensures consistent alignment geometry, improving both track performance and street drivability. Whether you are pushing your Supra or Z4 on the track or seeking longer tire life and improved grip on the street, these rear toe links deliver precise control and durability.

Key Features:

Engineered for maximum adjustability and reliability, the SPL Parts Rear Toe Links offer the following key features:

• Wide range of rear toe adjustment to accommodate lowered ride heights and aggressive alignment setups
• Black anodized, gun-drilled 2024 aluminum main links for lightweight strength and reduced unsprung mass
• 360-degree rotating clamp design for quick, precise toe angle adjustments
• Blue anodized titanium socket head cap screws for secure, easy-to-access clamp tightening
• FK spherical bearings and rod ends manufactured in Connecticut with Teflon liners for smooth articulation and quiet operation
• Self-lubricating, self-cleaning PTFE liner eliminates bushing deflection and reduces friction under load
• High load carrying capacity with excellent dynamic wear resistance and temperature tolerance from -65º to high operating ranges
• Made, engineered, and assembled in the USA to ensure premium quality and performance

Construction & Design:

The rear toe links are crafted from 2024 aluminum, chosen for its exceptional strength-to-weight ratio and corrosion resistance. The black anodized finish not only provides a sleek appearance but also protects against environmental wear. The main links are gun drilled to reduce weight without compromising structural integrity, contributing to improved suspension responsiveness.

The innovative 360-degree rotating clamp system allows for effortless and precise toe adjustments, a significant upgrade over the factory eccentric bolt and washer setup. This design enables fine-tuning of rear toe angles to suit various driving conditions and suspension modifications.

At the heart of the assembly are FK spherical bearings and rod ends featuring a chemically bonded PTFE liner. This liner ensures smooth movement, reduces noise, and prevents the deflection issues commonly associated with rubber bushings, delivering consistent handling performance on both street and track.

Installation & Fitment:

These rear toe links are a direct fit replacement for the 2020–2023 Toyota GR Supra and 2019+ BMW Z4 (G29) models. Installation requires standard suspension tools and basic mechanical knowledge. The design allows for quick adjustment without the need for disassembly, making alignment tuning straightforward. No modifications to the vehicle’s suspension components are necessary, ensuring a hassle-free upgrade.
