GS1-NIS002 · Grip Series Stage 1 Complete front & rear kit Springs + Sway Bars + Links
Whiteline Front and Rear Performance Suspension Kit - Nissan 370Z
GS1-NIS002
Most handling upgrades tackle one thing at a time. The Whiteline Grip Series Stage 1 does it all in one kit, performance lowering springs and a complete front and rear adjustable sway bar package, delivering a lower centre of gravity, flatter cornering, and sharper response in a single, cohesive upgrade designed to work together from the ground up.
Lowering the car reduces body roll. Bigger sway bars control what's left. Together they fundamentally change how the 370Z feels, more planted, more responsive, and more rewarding to drive.
The springs drop the front 25mm and the rear 35mm using a progressive rate coil design that improves both performance and appearance without harshness. The sway bar kit pairs a 27mm 2-point adjustable front bar with a 24mm 3-point adjustable rear bar, so you can dial in your exact handling balance on top of the lowered platform. Everything is engineered to work as a system, not a collection of parts.
