Whiteline GS1-SUB007 Grip Series Stage 1 Front & Rear Sway Bar and Lowering Spring Kit

The Whiteline Grip Series Stage 1 Kit (GS1-SUB007) is a complete front and rear suspension upgrade combining performance lowering springs and adjustable sway bars into a single, tuned package. Engineered as a cohesive system rather than a mix of brands, this kit delivers meaningful improvements in handling, body control, and driver confidence without sacrificing daily drivability.

The kit bundles two Whiteline sub-assemblies: the complete lowering coil spring set (WSK-SUB007) and the front and rear sway bar kit (BSK019), together providing a fully integrated suspension solution.
