Scion – D2 Racing Sport Coilover Kits

Summary & Key Benefits

D2 Racing Sport coilovers for Scion (tC, xB/xA, iM/iA, FR-S ZN6) balance predictable handling with daily comfort. The 36-step damping range and lower-mount ride-height adjustment preserve spring travel, enabling a usable drop without losing compliance.

Technical Basics

A coilover consists of a threaded damper body, spring, adjustable lower mount and a model-specific top mount. Set ride height at the lower mount to maintain preload. Many MacPherson fronts can add camber plates for alignment headroom. Materials: SAE9254 spring steel and 6061 aluminium housings/brackets.

The FR-S ZN6 (Toyota 86/BRZ) benefits from careful front camber and rear toe control; city-first tC/xB builds usually prefer softer damping. Wide wheels demand clearance checks after each change.

Selection Criteria

Pick exact fitment—tC AT10/AGT20, xB/xA, iM/iA, FR-S ZN6. Choose rubber top mounts for NVH control or pillowball for sharper feedback. Target a -50 to -60 mm street drop; more can harm geometry. For extra negative camber up front, use plates; the rear may need eccentric bolts/arms.

Installation & Maintenance

Clean interfaces, apply copper grease to threads and set height via the lower mount. Torque to OE specs and book a full wheel alignment after settling. Re-torque hardware and inspect dust boots after hard use.

Clunks at full lock usually mean binding or excessive preload. Return to baseline, re-check torque and consider a spring bearing. Winter care: rinse and protect threads.

FAQ

Is an FR-S comfortable on these?
Yes—36 steps let you bias comfort; rubber mounts keep NVH low.

How low can I go?
-50 to -60 mm is typical for the street; more risks geometry issues.

Do I need camber plates?
For track targets, plates expand front camber range.

Noise at full lock—why?
Often excessive preload or spring binding; check mounts and add a spring bearing.
