Dinan's performance spring set raises spring rates to take control of body roll and lowers the front of the car 1/2 in. while leaving the rear at stock height, which tightens up suspension geometry and gives a more aggressive stance. The stiffer rates cut front dive under braking and rear compression under acceleration, so weight transfer settles faster and the steering answers driver input more directly from parking speeds to the top of the range. Each spring is CNC wound from high tensile chrome silicon wire and shot peened for stress relief, then preset at the factory to prevent sag over the life of the car. With camber plates fitted the front rides 1/4 in. higher than that, for a 1/4 in. net drop.
