The Dinan 12-18 BMW 320i Coil Spring Set is a performance suspension upgrade designed for the F30 320i and 328i/330i models. Crafted with CNC wound high tensile chrome silicon wire and shot-peened for stress relief, these springs offer enhanced durability and consistent performance. The set provides greater control over body roll through carefully calibrated spring rates, resulting in improved handling and stability. Additionally, the springs lower the vehicle by 3/4 inch in both the front and rear, optimizing suspension geometry and delivering a more aggressive stance. The 30% increase in stiffness reduces suspension compression during acceleration and braking, offering a more controlled and confident driving experience. This upgrade also enhances grip at high speeds and improves responsiveness, making it suitable for spirited driving and performance-oriented use.

Designed to fit 2012-2018 BMW 320i, 328i, and 330i models with rear-wheel drive, this coil spring set is a direct replacement for the factory springs. It is ideal for street and performance driving, providing a noticeable improvement in handling, stability, and stance. The installation is a bolt-on upgrade, requiring no additional modifications. The kit includes the set of coil springs, engineered to deliver long-lasting performance and durability. Suitable for enthusiasts seeking to enhance their vehicle’s suspension dynamics, these springs improve overall ride quality and cornering capabilities while maintaining daily drivability.

Part #: D100-0909

Overview

The Dinan 12-18 BMW 320i Coil Spring Set is a high-performance suspension upgrade designed specifically for the F30 320i and 328i/330i models with rear-wheel drive. Crafted to enhance handling dynamics and improve the vehicle's stance, these springs are ideal for enthusiasts seeking a more responsive and confident driving experience. By carefully calibrating spring rates, Dinan's springs help reduce body roll, resulting in sharper steering and improved cornering stability. The lowered ride height of 3/4" in both the front and rear not only provides a more aggressive appearance but also optimizes suspension geometry for better control and balance during spirited driving. Constructed with CNC wound high tensile chrome silicon wire and shot-peened for stress relief, these springs are engineered for durability and long-lasting performance. The increased stiffness of approximately 30% helps minimize suspension compression during acceleration and braking, offering a more controlled and composed ride. Whether you're navigating tight turns or cruising at high speeds, these springs support enhanced grip and handling, inspiring greater confidence behind the wheel.

Key Features

Dinan's coil springs are designed with precision materials and manufacturing techniques to deliver consistent performance and reliability. Key features include:
  • Manufactured from CNC wound high tensile chrome silicon wire for strength and durability
  • Shot-peened for stress relief, ensuring long-term performance
  • Lowered ride height of 3/4" front and rear for improved stance and suspension geometry
  • Calibrated spring rates to reduce body roll and enhance handling response
  • Increased stiffness to improve grip and stability during high-speed driving
  • Engineered for use on BMW F30 320i and 328i/330i (RWD) models

Construction & Design

The springs are CNC wound with high tensile chrome silicon wire, a material chosen for its excellent strength and fatigue resistance. Shot-peening treatment further enhances durability by relieving internal stresses, ensuring the springs maintain their performance over the vehicle's lifespan. The precise design and manufacturing process result in a component that supports improved handling characteristics while maintaining ride quality.

Driving Feel & Feedback

These coil springs provide a more responsive steering feel and reduce body roll, making your BMW feel more agile and connected to the road. The lowered stance enhances the vehicle's visual appeal and improves suspension geometry, which contributes to better overall handling and driver confidence at both low and high speeds.

Installation & Fitment

Installation should be performed by a qualified technician familiar with BMW suspension systems. Proper alignment after installation is recommended to maximize handling benefits and tire wear.

What’s Included

The package includes a set of four coil springs designed specifically for the BMW 320i and 328i/330i (RWD) models from 2012 to 2018, providing all necessary components for a complete upgrade.
