2012-2018 BMW 3 Series F30/F31 RWD Non-M Traction Plus Ultra Coilovers

Transform the handling character of your 2012-2018 BMW 3 Series F30/F31 RWD Non-M with Riaction Traction Plus Ultra coilovers. Designed specifically for rear-wheel-drive configurations, this system enhances front-end grip, improves chassis rotation, and delivers greater control during aggressive corner entry and throttle application. The Traction Plus Ultra platform is built around our new digressive piston design, engineered to provide firm low-speed damping for improved body control and steering response while maintaining compliance as suspension velocity increases. This gives the F30 chassis a more planted feel through transitions without sacrificing real-world usability. Durability and precision are central to the TPU system. Each kit features a nickel-coated shock body to resist corrosion and environmental wear. The hex screw preload collar locking system ensures preload consistency under spirited driving conditions. This RWD Non-M configuration includes front-only pillowball camber upper mounts, allowing accurate camber adjustment for optimized tire contact and sharper steering input. Non-MacPherson components receive our signature orange coating for added protection and a distinctive finish. Every Traction Plus Ultra system is backed by a 2-year factory warranty. 🔧 Traction Plus Ultra Coilover Features: Full-Length Ride Height Adjustment 32-Level Damping Adjustment New Digressive Piston Valving Mono-Tube Damper Design Nickel-Coated Shock Body for Corrosion Protection Hex Screw Preload Collar Locking System Front Pillowball Camber Upper Mounts (F-Only) Signature Orange Coating on Non-MacPherson Components 44mm High-Flow CNC 6061 Aluminum Piston CNC 6061 Aluminum Floating Piston Polyurethane Oil Seals SAE9254 Cold-Wound Performance Springs Multi-Thickness Valving Shims Low-Gas Pressure Internal Design 7.5w Compounded Suspension Fluid Fully Rebuildable Coilover Assembly ⚙️ Factory Spring Rates: Front: 8K Rear: 12K 📧 International Orders: For international shipping inquiries, please email us at info@riactionshocks.com Maximize alignment control and sharpen RWD handling in your 2012-2018 BMW F30/F31 Non-M with Traction Plus Ultra coilovers,precision-built performance shocks from Riaction Performance Shocks.
