2014-2020 BMW M3 / M4 F80 / F82 / F83 (3-Bolt) Traction Plus Ultra Coilovers

Dial in precise chassis control and consistent load management in your 2014-2020 BMW M3 / M4 F80 / F82 / F83 (3-Bolt) with Riaction Traction Plus Ultra coilovers. Designed specifically for 3-bolt top mount configurations, the TPU system improves braking stability, reduces body roll under heavy lateral load, and delivers more predictable rear traction during aggressive acceleration. Traction Plus Ultra is built around our new digressive piston design, engineered to provide firm low-speed damping for stronger roll resistance and sharper steering precision while maintaining composure as suspension velocity increases. On the F8X chassis, this translates into improved mid-corner stability, flatter cornering under sustained load, and greater consistency during repeated high-performance driving. Each kit features a nickel-coated shock body for corrosion resistance and long-term durability. The hex screw preload collar locking system secures spring preload during track use and high-load conditions. Signature orange-coated non-MacPherson components add protection and a distinctive performance finish. Pillowball upper mounts are included where applicable and designed to integrate properly with the 3-bolt mounting setup for maximum steering precision and suspension articulation. Every Traction Plus Ultra system is backed by our 2-year factory warranty. 🔧 Traction Plus Ultra Coilover Features: 3-Bolt Top Mount Configuration 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 Signature Orange Coating on Non-MacPherson Components Pillowball Upper Mounts (When Applicable) 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: 14K 📧 International Orders: For international shipping inquiries, please email us at info@riactionshocks.com Deliver controlled high-load performance and precise steering response in your 2014-2020 BMW M3/M4 F8X (3-Bolt) with Traction Plus Ultra coilovers, engineered performance shocks from Riaction Performance Shocks.
