Toyota Supra A90 2019-2026 Coilover Installation Instructions
Welcome to the 2020–2024 Toyota Supra A90 coilover install instructions. This step-by-step guide is designed to make your installation process smooth and straightforward. We’ve included the recommended tools, factory torque specs, and key tips to help you get the best results. While this walkthrough highlights the Function and Form Type 3 Coilover kit, the same installation principles apply across similar suspension configurations. For reference, our test vehicle is a 2021 Toyota Supra A90 equipped with 255/35/19 front and 275/35/19 rear tires on factory wheels. Once installation is complete, we recommend scheduling a professional alignment after a short settling period to ensure proper handling, stability, and tire wear. A link to our video tutorial is available at the end of this post for those who prefer a visual guide.
The Toyota Supra A90, introduced in 2020, represents a modern return of an iconic performance platform. Built on a rigid chassis with near-perfect weight distribution and a rear-wheel-drive layout, the A90 Supra delivers exceptional balance, power, and driver engagement straight from the factory. Its advanced suspension design—featuring a MacPherson strut front and multi-link rear—provides a strong foundation for performance upgrades, especially when precision tuning is the goal.
Installing Function and Form Type 3 coilovers allows Supra A90 owners to fully dial in ride height, damping response, and overall handling character. With adjustable damping and performance-focused valving, the Type 3 system enhances cornering stability, reduces body roll, and sharpens steering feedback without sacrificing daily drivability. Whether you’re refining a street setup, preparing for spirited canyon driving, or building toward track use, coilovers are one of the most effective upgrades to unlock the A90 Supra’s full performance potential.
