BC Racing BR Series Coilovers – BMW 1 Series E88 Convertible 2007-2013

Upgrade the suspension of your BMW 1 Series E88 Convertible with BC Racing BR Series Coilovers, designed to provide a strong balance of performance, adjustability and everyday usability.

The BR Series is BC Racing’s recommended all-round setup for drivers who want improved chassis control for fast-road and track use while retaining a good level of ride comfort for regular road driving.

For this application, the kit is available with one spring-rate configuration only:

• Front: 5.5kg/mm
• Rear: 10kg/mm

5.5 / 10kg/mm Spring Rates

This BMW E88 Convertible application is supplied with:

• Front: 5.5kg/mm
• Rear: 10kg/mm

This combination is designed to provide a balanced setup for the heavier convertible chassis, giving improved body control while remaining suitable for mixed road and performance use.

It is well suited to:

• Fast-road driving
• Daily use
• Occasional track days
• Lowered road builds
• Drivers wanting improved control without an excessively harsh setup

Balanced for Road & Track

The BR Series is designed to offer a compromise between handling performance and ride quality.

A properly configured setup can help improve:

• Body control
• Steering response
• Cornering stability
• Chassis balance
• Weight transfer control
• Driver confidence

Adjustable Ride Height

BC Racing BR Series Coilovers allow ride height to be adjusted to suit your preferred stance and intended use.

This gives greater control over:

• Vehicle height
• Wheel fitment
• Arch clearance
• Centre of gravity
• Overall stance

Ride height should always be set with sufficient suspension travel and clearance for safe road or track use.

Adjustable Damping

The BR Series provides damping adjustment, allowing the suspension response to be tuned around:

• Road conditions
• Tyre choice
• Driver preference
• Vehicle setup
• Track use

This gives greater flexibility than a fixed spring and damper arrangement.

Everyday Usability

One of the key strengths of the BR Series is its ability to improve handling while retaining a usable level of ride comfort.

This makes it suitable for E88 owners who want a more capable suspension setup without turning the car into an uncompromising track-only build.
