Ride Height Drop
Designed to improve handling while maintaining excellent street drivability.
| Position | Ride Height Drop |
|---|---|
| Front | 1.8 inches |
| Rear | 1.4 inches |
The slightly lower front stance helps improve turn-in while maintaining BMW’s balanced chassis characteristics and reducing excessive wheel gap.
Progressive Rate Spring Technology
Unlike many entry-level lowering springs, D2 PRO utilizes a progressive spring rate.
Benefits include:
- Comfortable daily ride
- Increased spring rate during heavy compression
- Reduced body roll
- Improved steering response
- Better braking stability
- More predictable weight transfer
- Enhanced cornering confidence
This design allows the suspension to remain compliant over everyday road imperfections while delivering greater control during spirited driving.
Premium 55 Chrome Silicon Spring Steel
Every D2 PRO lowering spring is manufactured from 55 chrome silicon spring steel, offering outstanding fatigue resistance and long-term durability.
Construction highlights include:
- Premium 55 chrome silicon steel
- Progressive-rate spring design
- Precision cold-wound manufacturing
- Corrosion-resistant finish
- ISO 9001 certified manufacturing
- TÜV-approved production facility
This combination helps maintain consistent ride height while resisting premature spring sag over years of use.
Improve BMW Driving Dynamics
The F30 and F32 chassis already provide outstanding handling, but lowering the center of gravity unlocks even more performance.
Benefits include:
- Reduced body roll
- Sharper steering response
- Improved cornering grip
- Lower center of gravity
- Reduced brake dive
- Reduced rear squat
- Better high-speed stability
- More aggressive factory-plus appearance
The result is a BMW that feels more responsive without compromising the refinement expected from a premium sports sedan or coupe.
Compatible with OEM or Performance Shocks
D2 PRO lowering springs are engineered for use with:
- Factory BMW shocks
- OEM replacement dampers
- Performance sport shocks
- Adjustable aftermarket suspension
While factory dampers remain compatible, performance shocks are recommended for enthusiasts seeking the best balance of ride quality and handling.
