Nissan – D2 Racing Sport Coilover Kits

Summary & Key Benefits

D2 Racing Sport coilovers for Nissan S/Z/Skyline and R35 platforms deliver predictable grip with daily usability. The 36-step damping window and lower-mount height adjustment preserve spring travel, enabling a functional drop without compromising bump control.

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; many MacPherson fronts accept camber plates. Materials include SAE9254 spring steel and 6061 aluminium housings/brackets.

Applications include S13/S14/S15, 180SX, 350Z Z33, 370Z Z34, Z RZ34, Skyline R32/R33/R34 and GT-R R35. Drift setups differ from time-attack in rear camber/toe targets; adjust gradually and log changes. Verify ABS/loom brackets and anti-roll link positions during installation.

Selection Criteria

Pick exact fitment and choose top mounts to match use—rubber for NVH control vs pillowball for feedback. Start damping mid-range and adjust 1–2 clicks per change. Typical street drop: -50 to -60 mm vs OE; too much drop harms geometry and reduces travel. For extra negative camber, add plates up front and eccentric bolts/arms at the rear.

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 perform a full wheel alignment after settling. After hard use, re-torque hardware and inspect dust boots.

Clunks at full lock often indicate binding or excessive preload—return to baseline and consider a spring bearing. Winter protection (rinse and spray) extends thread life. Warning: incorrect preload and extreme lowering can cause damage and unsafe handling.

FAQ

Streetable on a 370Z?
Yes—36 steps let you bias comfort or response; rubber mounts feel closer to OE.

How low is sensible?
-50 to -60 mm is typical. Excessive drop hurts geometry and bump travel.

Drift vs grip setup?
Rear camber/toe differ—adjust in small steps and log results.

Clunks at lock—fix?
Reduce preload, check mounts, add a spring bearing if needed.
