Whiteline GS1-SUB001 Grip Series Stage 1 Suspension Kit - Sway Bar & Lowering Spring Kit

The Whiteline GS1-SUB001 Grip Series Stage 1 Kit is a complete performance suspension upgrade combining adjustable sway bars, performance lowering springs, and drop links into one cohesive package. Engineered to deliver a balanced improvement in handling, cornering stability, and ride comfort, this kit is the ideal entry point into serious suspension tuning.

The performance lowering springs reduce ride height approximately 30mm in the front and 25mm in the rear, lowering the vehicle's center of gravity to sharpen cornering response and improve overall appearance. Spring Rates: front springs are rated at approximately 3.5 kg/mm (196 lb/in) and rear springs at approximately 3.3 kg/mm (185 lb/in). The progressive-rate coil design improves performance while maintaining safety and ride quality. Springs are developed and manufactured in Europe to the finest tolerances for guaranteed exact fitment, and are engineered for optimal compatibility with both OEM and aftermarket shock absorbers.

The kit also includes Whiteline's signature adjustable front and rear sway bars. The 22mm 2-point adjustable front sway bar and 22mm 3-point adjustable rear sway bar allow precise tuning of understeer and oversteer balance, minimizing body roll without sacrificing ride quality. High-quality sway bar drop links and all necessary mounting hardware are included for a complete, straightforward installation.
