Nitron - elec-TRON ER3 Coilover Suspension Kit - BMW F82 M4

The evolution of the Nitron range is here - combining world-renowned quality and obsessive attention to detail with the latest in electronic valve technology. 

The elec-TRON ER3 coilover kit combines the Nitron proportional solenoid valve with independent manual compression control. R3 kits include our adjustable top mounts and race springs, and are designed for drivers looking to extract the most performance potential from their car on road or track. Piggyback or remotely mounted reservoirs allow for quick and simple independent adjustment of both high and low-speed compression, while the DCU handles active overall damping adjustment.

Nitron elec-TRON Range
The Nitron elec-TRON system combines our proven suspension engineering with precision electronic valve control to deliver exceptional handling, stability, and ride comfort. At its core is Nitron’s proprietary proportional solenoid valve, allowing independent adjustment of compression and rebound damping at each wheel. This enables the suspension to react instantly to changing conditions, with a rapid 6-8 millisecond response time and a wide adjustment range of 300 to 1800 mA. The system continually adjusts damping force based on inputs such as g load, vehicle speed, road surface, and driver control, resulting in a highly responsive and confidence inspiring drive. 

OEM EDC Integration
elec-TRON integrates directly with the OEM system, allowing full use of the original in car controls and driving modes. Rather than replacing the factory setup, it works alongside it to deliver sharper response, greater damping precision, and a more composed ride in every mode. The result is a suspension solution that complements the character of your BMW, enhancing performance and control without sacrificing the usability and comfort you expect from the ultimate driving machine.

Nitron “Fast Road” Spec
A road-biased performance setup with enough capability for occasional track use. Designed for drivers who are primarily on public roads with occasional track use, emphasizing comfort while still being performance-oriented.

Fast Road Core characteristics

• Driver Profile: 80% street/20% track
• Softer spring rates
• Softer damper valving
• More compliance over bumps/street imperfections
• Works well at near OEM ride height or mild drop
• Prioritizes ride quality + usable grip on imperfect roads
• Intended use: Daily driving/canyon runs or occasional HPDE or track day (few times per year)

Nitron “Track Day” Spec
A track-focused setup that sacrifices comfort for control and performance. More focused on track performance with stiffer springs + valving and lowered ride height. This is where the car starts to feel “on edge” (in a good way on track) but can be harsher on the street.

Track Day Core characteristics

• Driver Profile: 50%+ track/aggressive street
• Stiffer spring rates
• More aggressive damper valving
• Better body control, braking stability, and transition response
• Less forgiving on rough roads
• Intended use: Frequent track days and Aggressive driving/pushing the limit and for drivers prioritizing lap time over comfort

• Height adjustable (F/R: 10-35mm)
  
• 3-Way Independent Adjustment
• Factory EDC Adjustable w/ included manual high and low-speed compression adjustment
• 16 clicks high-speed and 26 low-speed clicks, setting the baseline for the semi active system
