Superpro Complete Poly Bushing Upgrade Kit - 3 Series E90/E91/E92/E93 All but M

BMW 3 Series E9x Polyurethane Suspension Bush Kit - Non M

Transform the way your BMW 3 Series drives with a complete polyurethane bush upgrade for the E90, E91, E92 and E93 platform. This uprated suspension bush set sharpens steering response, stabilises geometry under braking and cornering, and reduces unwanted movement from tired rubber components. Ideal for fast road use and track days, it delivers precision, consistency and confidence mile after mile.

Why upgrade to polyurethane bushes

• Sharper steering feel and improved front end bite
• Consistent alignment for better grip and even tyre wear
• Great durability with excellent resistance to heat, oils and road grime
• Carefully engineered for minimal increase in noise, vibration and harshness
• A genuine fit-and-forget solution for long term performance

What makes this kit special

Manufactured from a high-grade polyurethane elastomer, these precision moulded bushes control deflection far better than ageing rubber, keeping your chassis geometry where it should be. The material blends the compliance you want with the rigidity you need, so your 3 Series feels planted and predictable without the downsides of overly harsh race parts.

Vehicle compatibility

Suitable for BMW 3 Series E90 saloon, E91 touring, E92 coupe and E93 convertible models that are not M3. Perfect across the E9x non M range for drivers seeking a handling upgrade and long lasting replacement for worn factory items.
