2003-2008 BMW Z4 E85 Traction Plus Ultra Coilovers

Fine-tune the handling, balance, and driving dynamics of your 2003-2008 BMW Z4 E85 with Riaction Traction Plus Ultra Coilovers. Developed specifically for enthusiasts seeking greater chassis precision, Traction Plus Ultra combines advanced digressive damping technology with extensive adjustability to deliver exceptional control on the street, during spirited canyon drives, and on the race track. Built around our latest digressive piston valving, BMW Z4 E85 Traction Plus Ultra Coilovers provide firm low-speed damping to reduce body roll, sharpen steering response, and improve braking stability while allowing the suspension to remain composed over uneven pavement and high-speed impacts. The result is a more predictable chassis, improved cornering confidence, and consistent grip through every transition. Every Traction Plus Ultra coilover system is constructed using premium materials for long-term durability. Nickel-coated shock bodies provide outstanding corrosion resistance, while the hex screw preload collar locking system securely maintains spring preload during repeated high-load driving. Signature orange-coated non-MacPherson components add protection and a distinctive appearance, and pillowball upper mounts are included where applicable to maximize steering precision and suspension articulation. With 32 levels of damping adjustment and independent full-length ride height adjustment, drivers can precisely tailor suspension response without affecting spring preload. Whether you're building a balanced street car, preparing for autocross competition, or refining a dedicated track setup, Riaction Traction Plus Ultra Coilovers for the BMW Z4 E85 deliver the performance, consistency, and confidence serious enthusiasts expect. Every Traction Plus Ultra system is backed by our 2-year factory warranty. 🔧 Traction Plus Ultra Coilover Features Fits 2003-2008 BMW Z4 E85 Full-Length Ride Height Adjustment 32-Level Damping Adjustment Digressive Piston Valving Mono-Tube Damper Design Nickel-Coated Shock Bodies for Superior Corrosion Resistance Hex Screw Preload Collar Locking System Signature Orange Coating on Non-MacPherson Components Pillowball Upper Mounts (Where Applicable) 44mm High-Flow CNC 6061 Aluminum Piston CNC 6061 Aluminum Floating Piston Polyurethane Oil Seals SAE9254 Cold-Wound Performance Springs Multi-Thickness Valving Shim Stack Low Gas Pressure Internal Design Premium 7.5W Compounded Suspension Fluid Fully Rebuildable Coilover Assembly Why Choose BMW Z4 E85 Traction Plus Ultra Coilovers?
