Toyota MR2 W3 Lowering Suspension Cusco H&R
Toyota MR2 Roadster (W30 / ZZW30), choosing between Cusco and H&R depends on whether you want a full adjustable coilover setup or a simplified spring upgrade for the street.
1. H&R Sport Lowering Springs
H&R is the industry standard for those who want to improve the MR2’s stance and handling without the complexity or harshness of coilovers. These are designed to work with the factory shocks or “Sport” inserts like Koni Yellows.
-
Part Number: 29399
-
Lowering Drop: * Front: ~30mm (1.3″)
-
Rear: ~30mm (1.2″)
-
-
Spring Type: Progressive (softer during initial compression for comfort, stiffer during hard cornering).
-
Best For: Daily driving, “OEM+” look, and maintaining a comfortable ride quality while reducing body roll.
-
Note: If your factory shocks have high mileage, installing lowering springs may accelerate their wear. Pairing these with fresh KYB or Koni struts is recommended.
2. Cusco Suspension (Coilovers & Bracing)
Cusco offers high-end Japanese engineering focused on track performance and chassis rigidity. For the W30, their most popular line is the Street Zero A.
| Feature | Cusco Street Zero A (Coilovers) |
| Adjustment | 40-way adjustable damping (fine-tune stiffness). |
| Height Adjust | Full-length adjustable (change height without affecting spring preload). |
| Lowering Range | Front: -15mm to -45mm / Rear: -15mm to -55mm. |
| Spring Rates | Typically 5 kgf/mm Front / 8 kgf/mm Rear (Customizable). |
| Best For: | Spirited canyon driving, track days, and achieving a specific “stanced” look. |
Additional Cusco Upgrades for W30:
Because the MR2 W30 is a mid-engine convertible, chassis flex is a known issue. Cusco’s bracing is often paired with their suspension:
-
Type OS Front Strut Bar: Improves steering precision.
-
Lower Arm Bar (Version II): Connects the lower control arm mounts to prevent subframe flex.
