Learn More about elec-TRON RoadSport

In all Nitron systems you find exquisite machining and finishes, carefully detailed components and a COMPLETE system with nothing left to fetch or find.  Quality at every level inside and out down to the oil selection.  This results in reliability, strength and performance that are impossible to match at this price point and easy of use.

The Nitron elec-TRON RoadSport (eRS) coilover kit offers many of the same benefits of the eR1 kit but is more road orientated, optimizing comfort and daily usability, while integrating with your noise reducing OEM top mounts while still allowing height adjustability.  The eRS system is a purely electronic damper that utilizes the Nitron solenoid valve with all damping control being adjusted by the electronic controller (EDC, PASM, DSC etc).  The eRS kit installs into the factory harness for ease of use and is compatible with factory systems and interfaces.

Designed to withstand the abuse of the track, all Nitron systems are also reliable for the street enthusiast who drives long miles on public roads.  Whether you daily drive or track your setup the full range of Nitron systems are up for the job in all environments.

This kit is compatible with the BMW EDC system so no additional products are required.

Frequently Asked Questions

Which spring package do I want?

The Performance Street spring setup is designed to provide a sporting, but comfortable ride.  Performance on the road is very high, but may require the dual purpose springs if you intend to track your vehicle regularly.

The Dual Purpose spring setup provides track support for the enthusiast who drives to the track or still uses the car on aggressive drives.  HPDE on 200TW tires are ideal here and modest or no aero cars.  This will help keep tires from edge wearing on track due to excessive roll without killing roadworthiness.  Ride will be more taught, but can still be reasonably smooth.

The Track spring setup is for those who use slicks, have a bit more aero and just bias more completely towards track performance.  Obviously you can drive anything on the road, but you will have a firm ride with the track setup.  With the damping control offered by Nitron, this is not always a bad ride which matters over curbing and on bumpy tracks.

How does the electronic valve work?

The eR1 and eR3 have an electronic valve in the rod assembly controlled by the control unit instead of an adjuster knob. There is a piston and shim stack like the standard R1 and R3, but instead of a knob that adjusts a needle and seat with a fixed fluid bypass across the piston there is a dynamically controlled bypass.  This allows for seamless integration with the factory controllers or customizable control with an aftermarket unit so that you can have different adjustment settings under different conditions specific to your controller’s ability.  It’s like having an electronic gnome turning your shaft adjuster while you are driving.
