AST Suspension Adjustable Lowering Springs – 2019+ Toyota Supra A90 / BMW Z4 G29 | EDC Models

Lower and fine-tune the stance of your 2019+ Toyota Supra A90 or BMW Z4 G29 with AST Suspension's Adjustable Lowering Springs — engineered specifically for EDC (Electronic Damper Control) equipped models. AST's adjustable design offers a unique advantage over conventional lowering springs: ride height can be fine-tuned even after installation, giving you the flexibility to dial in your exact stance without removing the springs. Crafted from premium materials on advanced Wafios coiling machines in the Netherlands, these progressive-rate springs lower the center of gravity while preserving the comfort and compliance expected of an OEM-quality spring on the shared B58-platform A90/G29 chassis.

Key Features

• EDC (Electronic Damper Control) Compatible: Engineered specifically for Toyota Supra A90 and BMW Z4 G29 models equipped with EDC — compatible with the EDC damper system for a complete, integrated lowering solution without disabling or conflicting with the electronic damper control system
• Adjustable Ride Height – Post-Installation: AST's unique adjustable design allows ride height to be fine-tuned even after the springs are installed — unmatched flexibility compared to conventional fixed-height lowering springs
• Progressive Spring Rate: Progressive spring design balances a lowered stance with improved handling performance — softer initial rate for everyday comfort, firmer rate under load for improved body control and cornering performance
• Lowered Center of Gravity: Reduces the A90/G29's center of gravity for improved handling dynamics and a more purposeful stance — while maintaining the comfort characteristics expected of an OEM-quality spring
• Shared A90/G29 Platform Coverage: Fits both the 2019+ Toyota Supra A90 and BMW Z4 G29 — engineered for the shared B58-platform chassis used across both models
• Wafios Coiling Machine Precision: Manufactured on advanced Wafios coiling machines for consistent spring rate, precise free length, and superior quality control
