RoadSport

The elec-TRON RoadSport kit is engineered for drivers who want enhanced handling without compromising comfort or everyday usability. By retaining the factory top mounts and utilising a comfort-oriented spring and damping package, RoadSport preserves OEM suspension geometry while minimising noise, vibration, and harshness (NVH).

Ideal for fast road driving, it delivers improved vehicle dynamics while maintaining the refinement expected from a premium road car.

RoadSport Features

• Fully electronic damping control
• OEM top mount compatibility
• Comfort-oriented spring design
• Low NVH characteristics
• Improved road handling and ride quality
• Seamless BMW EDC integration

R1

The elec-TRON R1 is designed for drivers seeking maximum performance with minimal complexity. All damping adjustments are managed electronically by the elec-TRON control system, eliminating the need for manual damper adjustments while delivering exceptional adaptability on both road and track.

Each kit includes Nitron's adjustable top mounts and race springs, providing extensive suspension geometry adjustment and track-focused performance.

R1 Features

• Fully electronic damping control
• Adjustable top mounts included
• Race springs included
• No manual damper adjusters required
• Derived from the Nitron R3 platform
• Optional Front Axle Lift (FAL)

R3

The flagship elec-TRON system, the R3 combines Nitron's advanced electronic damping technology with independent manual high-speed and low-speed compression adjustment, giving experienced drivers and professional tuners the highest level of suspension control.

With 16 clicks of high-speed and 26 clicks of low-speed compression adjustment, the R3 allows the mechanical suspension setup to be tailored precisely before the elec-TRON system continuously fine-tunes damping in real time.

Available with piggyback or remote reservoirs for quick and convenient adjustment.

R3 Features

• Fully electronic damping control
• Independent manual high-speed compression adjustment
• Independent manual low-speed compression adjustment
• Piggyback or remote reservoirs
• Adjustable top mounts included
• Race springs included
• Optional Front Axle Lift (FAL)

Nitron elec-TRON Technology

At the heart of every elec-TRON suspension system is Nitron's proprietary proportional solenoid valve.

Unlike conventional electronically adjustable dampers, each shock absorber features its own independently controlled valve, allowing individual damping adjustment at each wheel. This enables the suspension to react instantly to changing driving conditions, delivering exceptional handling precision, stability, and ride comfort.

The proportional valve is mounted directly to the piston rod, where it precisely controls oil flow through the shim stack to regulate both compression and rebound damping. Combined with Nitron's gas-pressurised monotube architecture, this delivers exceptional consistency, fade resistance, and reliability under all driving conditions.

elec-TRON Technology Features

• Independent electronic damping control at each wheel
• Simultaneous compression and rebound adjustment
• Operating range: 300–1800 mA
• Ultra-fast 6–8 millisecond response time
• Piston rod-mounted proportional solenoid valve
• Gas-pressurised monotube construction
• Motorsport-derived engineering
• Full compatibility with BMW EDC systems

Intelligent Adaptive Damping

The elec-TRON control system continuously adjusts damping force in real time using multiple vehicle inputs, including:

• G-force and cornering loads
• Vehicle speed
• Road surface conditions
• Driver inputs

This intelligent control system constantly optimises suspension performance, providing:

• Improved grip
• Enhanced stability
• Sharper steering response
• Increased driver confidence
• Superior ride quality
• Greater consistency across changing road and track conditions

On R1, all damping adjustments are managed electronically for effortless performance.

On R3, the manual high- and low-speed compression adjusters establish the base suspension setup, while the elec-TRON system continuously fine-tunes damping to suit real-time driving conditions.

Optional Front Axle Lift (FAL)

Available as an option on both the R1 and R3 systems, the Nitron Front Axle Lift (FAL) adds everyday practicality to a lowered performance vehicle without compromising suspension geometry or handling.

At the push of a button, the hydraulic system raises the front axle by approximately 25 mm, allowing you to safely clear speed bumps, steep driveways, parking ramps, and other road hazards. Once clear, the suspension automatically returns to its normal ride height, preserving the performance characteristics of the suspension.

FAL Features

• Raises the front axle approximately 25 mm
• Typical lift time under 3 seconds
• Powerful 250W hydraulic pump
• Automatic shut-off function
• Illuminated in-cabin control switch
• Audible warning system
• Protects front splitters, lips, and underbody components

Complete FAL Kit Includes

• Hydraulic lift cylinders
• Hydraulic lines
• Hydraulic pump
• Wiring loom
• Controller
