Nitron elec-TRON RoadSport Coilover Kit for Aston Martin DB9

The Aston Martin DB9 was built to be driven, and the Nitron elec-TRON RoadSport coilover kit is developed around that expectation. Where most performance suspension upgrades push you toward a compromise between daily comfort and improved capability, the elec-TRON RoadSport doesn’t force that choice. It integrates directly with the DB9’s factory electronic damping system, using Nitron’s proportional solenoid valve and DCU-controlled damping to manage suspension response in real time without any manual adjustment required from the driver. The kit is designed around the factory OEM top mounts, keeping noise, vibration, and harshness in check so the car stays composed and comfortable on the road while delivering noticeably sharper handling over the stock setup. The hardware carries over core technology from the R1 kit, so there’s genuine engineering substance behind the comfort-focused brief. For owners who want to go further, the Nitron Spring Upgrade is available separately, lowering the DB9 with a slightly stiffer spring rate than OEM while keeping the ride compliance the car was designed around.

Nitron Spring Upgrade

• The Nitron Spring Upgrade for the Aston Martin DB9 is built for owners who want to sharpen the car’s road manners and bring the ride height down without committing to a full coilover conversion. The springs lower the DB9 between 20mm and 40mm, reducing body roll and improving stance, while a slightly stiffer rate over the OEM setup adds body control and responsiveness without stripping out the ride quality. The upgrade works within the existing suspension architecture, so the compliance and refinement the DB9 was designed around stays intact. It’s a focused change that improves the car without altering its fundamental character.

elec-TRON

• Each shock in Nitron’s elec-TRON system carries its own proprietary proportional solenoid valve, giving the DCU precise, independent damping control at every corner simultaneously. The system reads g-load, vehicle speed, road conditions, and driver inputs all at once, making damping corrections every six milliseconds. To put that in context, a blink of the human eye takes between 100 and 150 milliseconds. The suspension isn’t approximating what the road is doing; it’s keeping up with it in real time. elec-TRON is available in two configurations; OEM-Integration for vehicles that came from the factory with electronic damping, and Standalone Electronic Damping for those that didn’t.

Unique Technology

• Nitron builds every shock from precision components that go through a rigorous design and development process well before the unit reaches final assembly. The modular construction gives engineers the flexibility to work through each application properly without cutting corners on how parts are made or how they perform together under real load. Everything is machined to tight tolerances and checked individually by trained technicians; that level of quality control isn’t concentrated at the end of the process, it runs through all of it. New materials, finishes, and processes are put through extensive validation before they’re brought into production, with proprietary Nitron technologies integrated throughout to produce shocks that hold their own against the competition on road and track alike. That discipline in engineering is what the brand has stood on since day one.

Integration with OEM Electronic Systems

• The Nitron elec-TRON kit installs as a direct bolt-in replacement on vehicles equipped from the factory with electronic damping, picking up the OEM computer integration without any modification needed. Everything the factory system was designed to do continues to work exactly as intended; BMW’s EDC, Porsche’s PASM, and equivalent systems on other platforms stay fully operational, now with considerably more capable hardware behind them.

Bespoke Engineering

• Nitron doesn’t start with a generic damper and reverse engineer a fit. Every application is developed from scratch, with components, spring rates, and damping characteristics built around the specific platform rather than adapted from something in the same ballpark. The vehicle’s geometry, weight distribution, and suspension travel are factored into the design from the beginning, not addressed as afterthoughts. That’s the gap between a kit that happens to fit a car and one that was actually engineered for it.

Frequently Asked Questions

• Does the Nitron elec-TRON RoadSport coilover kit fit all Aston Martin DB9 model years? The Nitron elec-TRON RoadSport coilover kit is confirmed to fit the Aston Martin DB9 from 2004 to 2016. If you’re unsure about your specific build date or variant, we are happy to assist.
• How does the elec-TRON RoadSport integrate with the DB9’s electronics? The elec-TRON RoadSport integrates directly with the DB9’s factory electronic damping system, requiring no additional hardware or modification. Damping is managed entirely through the OEM system, so all factory features continue to function as intended with the Nitron hardware in place of the stock dampers.
• Does the elec-TRON RoadSport require manual damping adjustment? No. Damping is fully controlled by Nitron’s proportional solenoid valve and managed by the DCU. The system monitors g-load, vehicle speed, road conditions, and driver inputs simultaneously, making adjustments every six milliseconds without any input required from the driver.
• Does the elec-TRON RoadSport retain the OEM top mounts? Yes. The kit is designed around the factory top mounts, which keeps noise, vibration, and harshness in check and preserves the ride quality the DB9 was built to deliver on the road.
• What is the Nitron Spring Upgrade and is it included with the kit? The Nitron Spring Upgrade is available separately for DB9 owners who want to lower the car between 20mm and 40mm while running a slightly stiffer spring rate than OEM. It improves body control and stance while working within the existing suspension architecture, so the ride compliance the DB9 was designed around stays intact. It is not included as standard with the elec-TRON RoadSport kit.
• How does the elec-TRON RoadSport differ from the standard RoadSport kit? The RoadSport uses conventional passive dampers with combined 2-way manual adjustment across 24 clicks. The elec-TRON RoadSport replaces that with Nitron’s proportional solenoid valve and DCU-controlled electronic damping, managing suspension response automatically in real time without any manual input. Both kits retain the OEM top mounts and are built around road use, but the elec-TRON RoadSport adds the active damping layer for drivers who want the suspension to respond to conditions without having to adjust it themselves.
• Are droplinks included with the kit? No, droplinks are not included. The kit consists of four shock assemblies (+ four springs if upgrade is selected) covering front and rear.
• Is the Nitron elec-TRON RoadSport serviceable after purchase? Yes. Every elec-TRON RoadSport kit is fully serviceable. Nitron hand-builds each unit to order, and the design supports long-term maintenance rather than requiring full replacement when performance eventually needs refreshing.

About Nitron Suspension

Nitron Suspension has been at the forefront of precision suspension engineering since 1998, founded by Guy Evans with the goal of building high-performance shocks for enthusiasts and professionals alike. Over 200 dealers now carry Nitron products across Europe, Asia, the US, Australasia, and Africa. In 2008, the company moved into a dedicated facility in the UK’s Motorsport Valley, adding dynamometers, 5-axis CNC machines, and 3D CAD capabilities to support both growing demand and continued product development. A second expansion came in 2023 with a new office in Murrieta, California. The team behind every Nitron product draws from deep backgrounds in machining, materials technology, hydraulics, bike engineering, and F1 racing, with many engineers bringing firsthand experience as competitive drivers and riders. That depth of knowledge across both the technical and competitive sides of motorsport shapes every product Nitron develops.
