Why Upgrade to an IRS System?
IRS (Independent Rear Suspension) allows each rear wheel to move independently of the other. Unlike a traditional solid axle where both wheels react together, IRS dramatically improves handling, stability and ride comfort.
Key Benefits of Independent Rear Suspension
- Superior ride comfort on uneven roads
- Improved cornering and stability
- Reduced unsprung weight for enhanced performance
- Better rear-end traction under acceleration and braking
- Modern rear geometry with improved camber & toe control
- Ideal for high-performance street cars and custom builds
