WHY DOUBLE-ADJUSTABLE WITH A RESERVOIR MATTERS

The JRZ RS PRO Coilovers Toyota Supra A90 use a remote reservoir to deliver consistent damping under heat and sustained load — built around JRZ monotube technology that eliminates the fade you get from compact-body dampers on track. Independent compression and rebound let you separate bump response from body control, giving you the same tuning flexibility found in the 12 Series but with reservoir-grade thermal capacity for repeated hard laps.

• High-speed compression (14 clicks) — controls how the damper responds to kerbs, impacts, and surface changes. Sets the blow-off threshold so the tire stays planted without transmitting harshness to the chassis.
• Rebound (21 clicks) — controls how the damper extends after compression. Critical for weight transfer, corner exit traction, and overall chassis composure under load.

With 14 compression clicks and 21 rebound clicks, every adjustment is noticeable but proportional. You won’t waste time chasing changes that don’t exist — each click directly affects handling.

DIVORCED SPRING CONFIGURATION

This RS PRO kit uses a divorced spring layout on the rear axle. Instead of wrapping the spring around the damper body (coilover style), the spring mounts separately on the factory spring perch while the damper mounts independently. This preserves the factory rear spring mounting geometry and can be the better choice when rear fitment or clearance is tight — especially with aftermarket wheels, big brake kits, or trunk-mounted battery relocations.

The damper itself is identical to the rear coilover version — same valving, same reservoir, same adjustment range. The difference is packaging. If you want the spring on the damper body for a more traditional coilover setup, see the rear coilover variant (separate listing).

WHY THE SUPRA A90 BENEFITS FROM A RESERVOIR DAMPER

The A90 Supra’s B58 inline-six and short wheelbase make it responsive but demanding on suspension. Under hard track use, twin-tube dampers without a reservoir will heat-soak during a 20-minute session and fade — you lose consistency exactly when you need it most. The RS PRO’s remote reservoir adds fluid volume and cooling surface area, keeping damping forces stable from your first lap to your last.

The adjustable gas pressure also lets you fine-tune cavitation resistance based on your spring rates and driving style — something no sealed twin-tube can offer. For Supra owners pushing the car on track days, time attacks, or spirited canyon roads, the RS PRO delivers reservoir-grade performance without the complexity of a third adjuster.

JRZ RS PRO COILOVERS TOYOTA SUPRA A90 FITMENT

Fits 2019-2026 Toyota Supra A90 (all variants including 2.0T and 3.0T). Valving and spring selection are tailored to the Supra’s front-engine, rear-drive weight distribution and multi-link suspension geometry. We recommend a full four-wheel alignment and corner balance after installation at a shop experienced with performance suspension setups.
