WHY THE 11 SERIES IS THE MOTORSPORT ENTRY POINT

The JRZ 11 Series Coilovers Toyota Supra A90 — a double-adjustable motorsport damper built around the JRZ 8060 piston — the same valving platform found in the 12 Series and used in professional racing. Independent compression and rebound adjustment gives you direct control over how the car responds to both inputs and surface conditions, without the complexity of a triple-adjustable system.

• Compression — controls how the damper resists being compressed under braking, turn-in, and over bumps. Higher compression damping reduces body roll and pitch; lower settings improve compliance over rough surfaces.
• Rebound — controls how quickly the suspension extends after compression. Faster rebound keeps the tyre loaded through successive bumps; slower rebound prevents the car from feeling unsettled on smooth pavement.

The A90 Supra’s front-engine, rear-drive layout makes it particularly responsive to compression and rebound tuning. Two independent adjustments let you balance body control against ride quality — stiffening compression for corner entry without making the car harsh over kerbs, or slowing rebound on one axle to shift the balance from understeer to oversteer.

THE 8060 PISTON AND BLOW-OFF VALVE

The 11 Series shares the JRZ 8060 motorsport piston with the 12 Series — a valving platform designed for linear damping force progression across the entire stroke. Linear damping means each click of adjustment produces a proportional, predictable change in damper behaviour. There are no dead spots in the adjustment range and no sudden transitions in force.

The integrated blow-off valve adds a safety margin for unsprung mass control. When shaft velocity exceeds a threshold — a sharp kerb strike, a pothole, or a sudden surface change — the blow-off valve opens to prevent excessive force from reaching the chassis. This protects the damper internals, prevents wheel hop, and keeps the tyre in contact with the road surface through high-energy events.

JRZ 11 SERIES COILOVERS TOYOTA SUPRA A90 FITMENT

Engineered for the 2019-2026 Toyota Supra A90 platform (all variants including the 2.0 and 3.0). Every set is valved by Meisterschaft to a Supra-specific spec that accounts for the A90’s weight distribution and chassis dynamics. Quick disconnects are included on the front as standard; rear quick disconnects are available as an optional add-on for easier damper removal at the track.

Camber plates (p/n 99 033 A90 01) and rear top mounts (p/n 95 60 07 52) are available separately — both are JRZ-specific components designed to work with the 11 Series damper geometry.
