How to choose the setup
Choose the spring package around tire grip, track frequency and the intended ride quality. FRS means Fast Road Specification; TDS means Track Day Specification. These are spring/build choices, not electronic driving modes. The supplier base part number alone does not capture every ordered configuration.
Factory electronic damping
This is a manually adjusted suspension kit. If the car has factory electronically controlled dampers, confirm the appropriate cancellation or conversion hardware with the installer. The listing should not be interpreted as retaining factory electronic damper adjustment.
Installation and ordering
Provide the model year, chassis, factory suspension equipment and intended use when specifying the order. Have the installer verify the mounts, usable travel, wheel clearance and any required electronic hardware. Confirm lead time for the selected configuration; catalog availability is not a promise of immediate dispatch.

Product FAQs
Can I adjust compression separately from rebound on R1?
No. Manual NTR R1 uses a combined adjustment. R3 provides independent controls if separate tuning is a priority.
What should I evaluate before changing the damping setting?
Start with tire pressures, alignment and a consistent baseline. Assess one change at a time rather than using damper adjustment to compensate for an unresolved chassis issue.
What Supra details should I provide when selecting the kit?
Provide the model year, A90/A91 application, steering side, factory damping equipment and any existing suspension changes.
