Hobbyists and racers looking to sharpen handling can fit the XRAY 378095 Progressive Shock Spring for a measurable change in traction and steering feel. It is designed to slot into detailed setup work without overhauling the car.
The progressive rate gives softer initial compliance and increased stiffness under larger compressions, covering the C=1.4 to 1.9 span. That allows the suspension to stay composed under varied cornering loads.
Use this spring when tuning for improved corner exit or when seeking a more consistent front end through full travel. It complements adjustments to oil and mounting to dial in handling.
