The F95 X5 M and F96 X6 M carry serious performance hardware from the factory, but their tall SUV ride height undermines the S63M's capabilities with avoidable body roll and sluggish geometry. Dinan's Performance Spring Set drops both trucks 1-3/8" (35mm) front and rear — a significant correction that brings the suspension geometry into the range where the S63M can do its best work.
Each dual-rate spring is CNC wound from high-tensile chrome silicon wire, shot-peened for stress relief, and preset to eliminate sag. The 20% increase in spring stiffness front and rear directly attacks body roll under hard cornering, reducing squat under acceleration and dive under braking for a much more composed dynamic.
