Toyota – D2 Racing Sport Coilover Kits

Summary & Key Benefits

D2 Racing Sport coilovers for Toyota harmonise daily civility with track-day precision. Coverage includes GR Yaris GXPA16, GR86/GT86 ZN8/ZN6, Supra A90/A91, Corolla (including G16E-GTS GR), Celica T23, Yaris and mainstream sedans/SUVs. The 36-step damping range and lower-mount ride-height adjustment preserve effective spring travel for predictable grip.

Technical Basics

A coilover comprises a threaded damper body, spring, adjustable lower mount and a model-specific top mount. Adjust ride height at the lower mount to maintain preload and bump travel. Materials include SAE9254 spring steel and 6061 aluminium brackets/housings; many MacPherson fronts can add camber plates to widen alignment windows.

Model notes: the GR Yaris GXPA16 short wheelbase dislikes excessive rear stiffness; the Supra A90/A91 multilink rear benefits from travel preservation. On adaptive-damping cars, a cancellation accessory may be required. Excessive lowering harms geometry and reduces travel—adjust in small steps and verify clearances with wider wheels.

Selection Criteria

Pick exact fitment by generation. For commuting choose rubber top mounts; for time-attack choose pillowball mounts. A streetable drop is -40 to -60 mm vs OE. If you need extra negative camber, use plates up front and eccentric bolts/arms at the rear; always recheck toe after changes.

Installation & Maintenance

Clean mating faces, apply copper grease to threads and set height via the lower mount (not spring compression) to avoid excessive preload. Torque to OE specs and book a full wheel alignment after settling. After spirited use, re-torque hardware, inspect dust boots and fine-tune damping based on tyre temperature and surface.

FAQ

How low can I drop a GR Yaris for the street?
Roughly -30 to -50 mm is typical; more risks geometry issues and bottoming.

Is an A90 Supra daily-friendly?
Yes—36 steps let you bias comfort, with rubber mounts keeping NVH low.

Do I need camber plates on a GR86?
They help reach front camber targets for track days; the rear may need eccentric hardware.

Noise at full lock—what’s wrong?
Often binding or too much preload; re-check torque and consider a spring bearing.
