Dinan 20-26 Toyota GR Supra (A90/A91) Performance Spring Set

Dinan's Performance Spring set for the GR Supra provide greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the car for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot-peened for stress relief to last the life of the car. The increase in stiffness will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip for high-speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at low speeds up to the top speed of the vehicle. A90 / A91

Upgrade the handling and stance of your 2020-2026 Toyota GR Supra with the Dinan D100-0938 Performance Spring Set. Designed for A90 and A91 chassis vehicles, these performance springs use carefully calibrated rates to reduce body roll, improve steering response, and provide a more controlled feel during acceleration, braking, cornering, and high-speed driving. The lowered ride height also enhances suspension geometry and gives the GR Supra a more aggressive appearance.
The Dinan performance springs are CNC-wound from high-tensile chrome silicon wire and shot-peened for stress relief, helping deliver consistent performance and long-term durability. Preset construction helps prevent spring sag over time, while the increased stiffness reduces rear suspension compression under acceleration and front suspension dive during braking. The result is more responsive handling and improved driver confidence without sacrificing the engineered balance of the vehicle.
For 2.0T GR Supra models, the set lowers the vehicle approximately 1.1 inches at the front and 0.5 inches at the rear, with spring stiffness increases of 71 percent in front and 38 percent in the rear. For 3.0T GR Supra models, the vehicle is lowered approximately 1 inch in front and 0.7 inches in the rear, with a 25 percent increase in spring stiffness at both ends. The kit includes two front and two rear linear-rate springs. A separate Ride Quality and Handling Kit is sold separately. Compatible with select 2020-2023 Toyota GR Supra applications and designed for use through the 2026 model range where fitment is confirmed.
