The Thunder Lane suspension systems for the Toyota GR platform are engineered for drivers that demand real performance, consistency, and tuning precision. This collection includes built-to-order coilover and chassis solutions for GR Supra A90 and GR86 to maximize mechanical grip, usable suspension travel, and predictable damping behavior.
Whether it is street performance, autocross, or serious track use, every system in this collection has been configured around how that car is actually driven—not some generic spring and damper package. Spring rates, valving, and chassis balance are selected to work together as a complete system.
Included Platforms
Toyota GR Supra A90 - TL-ONE and TL-PRO coilover systems
Toyota GR86 / GT86 / SUBARU BRZ - TL-ONE Grip Kit with coilovers and sway bars
Toyota MR2 / MRS ZZW30 - TL-ONE coilover system
GR Supra offerings range from the refined, street-and-track-focused TL-ONE to the TL-PRO 3-way adjustable system with remote reservoirs for advanced tuning and competition use. The GR86 Grip Kit combines TL-ONE coilovers with adjustable sway bars to address the entire chassis and deliver balanced, confidence-inspiring handling.
All Thunder Lane GR suspension systems use monotube dampers, application-specific valving, and are fully rebuildable—so that your setup can evolve as tires, alignment, and driving goals change over time.
