RS*R M115D Down Sus Lowering Springs

The RS*R M115D Down Sus Lowering Springs are a vehicle-specific performance lowering spring set engineered to reduce ride height while maintaining everyday drivability. Designed with careful attention to factory suspension geometry, shock dampening rates, and OEM spring characteristics, the Down Sus lineup delivers a meaningful drop without sacrificing ride quality or causing premature wear on stock shock absorbers.

These springs provide a mild-to-moderate lowering drop that tightens up the stance, reduces fender gap, and lowers the center of gravity for improved cornering response and road feel.

Key Features:

• Approximate Front Drop: 30–35 mm (approx. 1.2–1.4 in)
• Approximate Rear Drop: 30–35 mm (approx. 1.2–1.4 in)
• Front Spring Rate: 6.00 kgf/mm
• Rear Spring Rate: 4.04 kgf/mm

The M115D is a bolt-on upgrade that delivers a sportier stance and sharper handling characteristics straight out of the box.
