Lowering Specifications

Godspeed Traction-S springs provide a sporty ride height designed to improve handling without creating excessive clearance issues.

*Actual ride height may vary depending on engine configuration, factory suspension package, and vehicle condition.

The moderate lowering height gives the E90 a cleaner factory-plus appearance while preserving everyday drivability.

Premium SAE 9254 Spring Steel Construction

Godspeed manufactures each Traction-S spring using one of the industry’s preferred performance spring materials.

Construction highlights include:

• SAE 9254 high-tensile spring steel
• Cold-wound manufacturing process
• Multi-stage heat treatment
• Precision-balanced spring rates
• Powder-coated corrosion-resistant finish
• Designed to resist long-term spring sag

The manufacturing process strengthens the steel before coil formation, producing springs capable of maintaining their ride height and handling characteristics for years.

Improve BMW Driving Dynamics

BMW’s E90 chassis is already known for excellent balance, but lowering the suspension further enhances its capabilities.

Benefits include:

• Faster steering response
• Reduced body roll
• Improved turn-in
• Better cornering stability
• Lower center of gravity
• Improved weight transfer
• Reduced brake dive
• Increased driver confidence
• Aggressive European sport sedan stance

Whether commuting, enjoying mountain roads, or attending weekend BMW meets, the suspension feels more responsive and connected.

Comfortable Daily Driving

Unlike many extremely stiff lowering springs, the Traction-S series is designed to maintain ride comfort suitable for everyday use.

Drivers can expect:

• Smooth highway ride
• Controlled suspension movement
• Reduced float
• Better chassis composure
• Improved road feel without excessive harshness

The result is a suspension upgrade that complements the E90’s luxury-sport personality.

Compatible with OEM or Performance Shocks

Godspeed engineered these springs for compatibility with:

• Factory BMW shocks
• OEM replacement dampers
• Performance sport shocks
• Adjustable aftermarket suspension

Although OEM dampers may be retained if they remain in good condition, pairing these springs with performance shocks provides the best combination of comfort and handling.

Precision Engineered for Quiet Operation

Each Traction-S spring is precision manufactured and inspected to minimize unwanted suspension noise.

Designed to help prevent:

• Spring rattle
• Suspension clunks
• Coil binding
• Rubbing under normal suspension travel

This attention to detail helps maintain the quiet, refined driving experience expected from a BMW.
