SuperPro Poly Bush Kit - Polyurethane (Urethane) Suspension Bushings for BMW 1 Series F20/F21, Complete Front & Rear Set, Performance Handling & Chassis Upgrade, Fast Road & Track

Polyurethane Suspension Bush Set for BMW F20 and F21

Transform the way your BMW F20 or F21 drives with a premium polyurethane suspension bush package designed for sharper steering response, improved stability and long lasting performance. This comprehensive urethane bush bundle replaces tired factory rubber mounts to keep your alignment consistent under load, helping the car feel tighter, more precise and more predictable on fast road and track.

We have installed this set in house and the results speak for themselves. Customers report a more connected front end, better turn in, reduced flex and a confident, planted rear. It is the ideal suspension refresh for enthusiasts who want reliable handling gains without constant maintenance.

Why choose this polyurethane bush set

• Increased chassis control for confident cornering and braking
• Durable polyurethane resists wear, fluids and heat better than OE rubber
• Consistent geometry under acceleration and lateral load for predictable grip
• Fast road and track day friendly while keeping day to day use civilised
• Direct replacement components engineered for the F20 and F21 platform
