The BC Racing BR Series Coilovers are popular among BMW E46 enthusiasts seeking improved handling, ride quality, and adjustability. These coilovers are designed to balance performance and comfort, making them ideal for daily driving and spirited track use.
Design and Build Quality
The BR Series Coilovers feature a monotube design, which provides superior performance compared to twin-tube designs due to better heat dissipation. The high-strength steel construction ensures durability and longevity, even in demanding conditions. The aluminium top mounts further reduce weight while maintaining rigidity. Each coilover is paired with high-tensile strength springs, delivering responsive handling without compromising ride comfort. The coilovers come pre-assembled with all necessary components, making installation straightforward for most DIY enthusiasts or professional mechanics.
Adjustable Features
The BR Series Coilovers offer 30 levels of damping adjustment, allowing users to fine-tune the suspension setup to suit their driving preferences. This adjustability affects compression and rebound, offering fine control over how the car reacts to various road surfaces. The ride height can also be adjusted independently of spring preload, lowering or raising the car without affecting spring tension.
This feature ensures you can achieve your desired stance while maintaining optimal handling performance. Additionally, the camber plates included in the kit allow for further suspension tuning, giving you control over how much camber you want to run.
Performance
The BR Series Coilovers are designed to improve handling by reducing body roll, improving steering response, and providing better grip. The suspension offers a more predictable and stable ride on the track, helping drivers maintain control during high-speed cornering or hard braking. On the street, the coilovers can be dialled down for a more compliant ride, absorbing bumps and potholes while still feeling sportier than stock suspension.
Comfort
Despite being performance-focused, the BC Racing BR Series Coilovers are versatile enough to deliver a comfortable ride for daily driving. The damping adjustment range allows you to soften the suspension on rougher roads or harden it for more spirited driving, making the BR Series coilovers suitable for both commuting and weekend track events.
