Swiss Homologation Included

All BC Racing coilover kits available at www.touge-shop.ch come included with Swiss homologation documents. This ensures that your suspension upgrade is not only high-performance, but also fully legal for road use in Switzerland.

BC Racing BR Series – Street & Track Ready

The BR Series is BC Racing’s most popular and versatile coilover. Designed for daily drivers who also want solid performance on the track, this series strikes a perfect balance between comfort and control.

Key Features:

• 30 levels of simultaneous compression & rebound adjustment

• Ride height adjustment independent of spring preload

• Monotube shock design for better heat dissipation

• Custom spring rates available

• Fully rebuildable and revalvable

Ideal for: Street use, spirited driving, occasional track days

BC Racing DS Series – Digressive Track Performance

The DS Series builds on the BR platform but features digressive valving, offering increased low-speed damping force. This results in better handling and feedback, especially during corner entry and transitions — perfect for serious track enthusiasts.

Key Features:

• Digressive piston for enhanced track performance

• More responsive compression & rebound

• Same adjustability and build quality as BR Series

Ideal for: Aggressive street driving, track days, autocross

BC Racing RM Series – Inverted Dampers for Track Abuse

Key Features:

• Inverted strut design (front or rear, depending on vehicle)

• Increased strength under high lateral loads

• 30-way damping adjustability

• Separate height and preload adjustment

Ideal for: Track cars, drifting, race applications

BC Racing ER Series – 2-Way Adjustable Performance

Looking for more control? The ER Series gives you independent compression and rebound adjustability, allowing you to fine-tune your suspension to a high level of precision. It also features external reservoirs, increasing fluid capacity and improving heat dissipation.

Key Features:

• 2-way (independent) damping adjustment

• External reservoirs

• Ideal for extended track sessions

• Monotube inverted or upright, depending on vehicle

Ideal for: Time attack, endurance racing, high-level motorsport

BC Racing HM Series – Inverted with External Reservoirs

The HM Series combines the benefits of the RM’s inverted design with the external reservoirs of the ER Series. It’s the best of both worlds for those who demand strength and adjustability under race conditions.

Key Features:

• Inverted damper design

• External reservoirs

• 2-way damping adjustment

• Custom spec options available

Ideal for: Road racing, competitive motorsport, aggressive setups

BC Racing ZR Series – 3-Way Pro Level Dampers

Key Features:

• 3-way damping adjustment

• External reservoirs

• Highest level of tunability

• Fully custom-built to spec

Ideal for: Professional motorsport, full race builds, expert tuners

Front Camber Plates: Included When Applicable

BC Racing includes adjustable front camber plates on all coilovers for vehicles with MacPherson front suspension. This allows for quick and easy alignment adjustments, especially useful for aggressive setups or track alignment specs. If your vehicle’s suspension layout supports camber plates, they are always included in your kit.
