Swift Springs Spec-R Lowering Springs – Toyota GR Supra (A90/A91)

OVERVIEW

Swift Springs' Spec-R line uses the company's signature small-ID, high-travel spring design for a more linear rate through the shock's travel than a typical high-ID lowering spring. Designed for the A90/A91 GR Supra chassis, the Spec-R kit lowers ride height for street and track use while working with the factory adaptive damper valving.

SPECS

• Front spring rate: 4.8 kgf/mm
• Rear spring rate: 12.0 kgf/mm
• Front drop: approx. 1.2 in
• Rear drop: approx. 1.2 in
• Swift small-ID, high-travel spring construction

PARTS INCLUDED

• Front and rear Spec-R lowering springs (set of 4), as supplied by Swift Springs

TECH RESOURCES

Required Parts

• None. Swift Springs specifies no additional hardware beyond the factory strut/shock assembly for installation.

Notes

• Swift Springs does not publish an installation PDF or a vehicle-specific install video for this kit; installation follows standard spring-compressor procedure onto the factory struts/shocks.
• Swift's product page describes fitment as "designed for the A90 and A91 chassis" without splitting by engine; this listing is scoped to the 3.0L B58 model consistent with the rest of Speed Logic's Supra catalog. Confirm with Swift before assuming B48 2.0L fitment.
