We can offer Vauxhall Signum suspension kits for most models including the 1.6i, 1.8i, 2.0i, 2.0Turbo, 2.2i, 1.9CDTi, 2.0DTi, 2.2DTi, 2.2CDi, 2.8i, 3.0i, 3.0CDTi and 3.2i.  The spring rates are increased to decrease the amount the car rolls when cornering and the ride height is reduced approx -30 mm to -50 mm depending on exact model.  The ride height drop lowers the cars centre of gravity this improves handling and road holding.  The kit also includes shock absorbers which are uprated to suit the lowering springs and in most cases include shortened piston rods.
