Whiteline Grip Series Stage 1 Suspension Kit for Select 2008-2014 Subaru Impreza & WRX (GS1-SUB005)

Fits select 2008-2014 Subaru Impreza and WRX models (Base, Limited, Premium, Sport, and WRX submodels). This Whiteline Grip Series Stage 1 Kit (GS1-SUB005) is a comprehensive suspension solution designed to eliminate body roll, improve turn-in response, and provide a lowered, aggressive stance without sacrificing ride quality.

The kit features progressive rate lowering springs that provide a 25mm drop front and rear, utilizing spring rates of 4.9kg/mm (274lb/in) at the front and 3.7kg/mm (207lb/in) at the rear. To manage lateral loads, the package includes 22mm heavy-duty sway bars: a 2-point adjustable bar for the front and a 3-point adjustable bar for the rear. These bars are paired with adjustable drop links featuring heavy-duty steel ball joint ends that allow for on-car length adjustment up to 25mm to eliminate sway bar preload.
