RS5 Transformed: KW DDC Coilover System


Redline Speed Worx (RSW) recently had the opportunity to work with an avid track enthusiast on both upgrading and fine tuning the chassis of his 2014 Audi RS5!

The owner came into our facility already well aware of the capabilities of the KW DDC Coilover System upgrade, and wanted our skilled help in both the technical installation of the product as well as fine tuning the vehicle's new suspension system for optimal balance of road & on track performance.

What is KW Suspension's DDC Coilover Technology with Electronic Damping Control?

With the new Dynamic Damping Control, DDC, KW has designed a new coilover suspension, which uses the original 3-way button to adjust the damping. KW combines the individual height adjustability of the coilover suspension with the adaptive OEM damping control.

The driver can choose between 3 modes: "Comfort" for bad road conditions or just a relax ride, "Normal" for sporty daily use as the best compromise between performance and ride comfort or "Sport" for best handling and response.

Individuality by the push of a button.

The KW DDC coilover kit allows an individual lowering and three different damper setups by the push of a button for an easy adaptation to the respective road conditions. It can be chosen between a basic setup for sporty driving on normal roads, a comfortable setup for un-even/poor road surfaces and the extra sporty setup for maximum driving dynamics on well maintained roads and race tracks.

The different damper settings will be controlled electronically with a proportional valve that regulates the flow of oil in the damper in milliseconds.  The KW DDC coilover kit is available as "DCC Plug&Play" solution for VW cars with standard electronic damping control for an easy replacement of the series dampers.  With the KW DDC coilover kit "DDC ECU" an electronic damping control system can be upgraded, which also may optionally be controlled and programmed via an app.

KW coilover kit DDC "Plug & Play"

The Plug & Play solution of the KW DDC (Dynamic Damping Control) coilover kit was developed for VW / Audi models, which have a standard Electronic Damper Control (VW / Audi DCC). The standard dampers can easily be replaced by the KW DDC coilover kit.

The existing control unit and the interior switch that was installed for the operation of the damper control will be kept. For the first time the KW DDC coilover kit combines the advantages of a KW coilover kit and the comfort of standard damper control. By pushing a button, the driver can choose between Comfort-Normal- and Sport-setup. Also the KW coilover kit allows an individual lowering in the TÜV-tested adjustment range.

KW DDC coilover kit "DDC ECU"

The KW DDC (Dynamic Damping Control) coilover kit with ECU (Electronic Control Unit) was developed for individual lowering and installation of an electronic damping control system. The scope of delivery contains a KW inox-line coilover kit with electronically controlled dampers, a high-performance control unit, the car specific cable set with control switch and a detailed manual for an easy installation.

The KW DDC coilover kit has three car specific developed damper settings. By the push of a button the driver can choose between the Sport basic setup, a very Sporty and performance-oriented Sport + setup and the Comfort mode for un-even/poor road surfaces. The height adjustment of KW coilover kits also allow an individual lowering within the TÜV-tested adjustment range.

KW "DDC App" (only for DDC ECU)

Optional for KW DDC ECU solutions available damping control for iPhone, iPod or iPad. With the DDC app you can also save up to five own individual setups programmed by yourself, and share them with your friends via e-mail. A variable damper setting of 0% (maximum comfort) up to 100% (maximum Sport+), as well as the separate damper setting for front and rear axle is possible and will be transmitted via iPhone within milliseconds to the dampers. For the communication between iPhone and KW DDC control unit, a KW DDC W-LAN module is required.

The KW DDC APP is available for free in the App store.

Some Assembly Required.

During the course of the installation of KW DDC Coilover upgrade on the Audi RS5 we also took this time to install & complete a few additional upgrades to further enhance the abilities of the RS5. The first of which was a set of SPC Adjustable Upper Front Control Arms. As every AUDI owner knows, there is limited ability (on stock components) to dial in both camber and caster.  The adjustable upper SPC units solve exactly that problem, and when setting a vehicle up for both optimal road & track day driving characteristic's this is a crucial component.


Upon completing the installation of the upgrade on the Audi RS5, the vehicle went right onto our Hunter Engineering Hawk Eye Alignment Rack to perfectly dial in the Audi's front & rear suspension geometry!

Audi RS5 Alignment

Due to the customer being an avid track enthusiast we wanted to ensure his newly equipped RS5 was 100% dialed in, therefore we opted to complete a full precision corner balancing service.  Setting ride heights via measurement on a level surface was just not going to be enough, we had to very accurately measure the weight on all four wheels at the same time.

Audi RS5 KW DDC Corner Balance

What’s the point? Well the amount of weight or pressure on each tire will affect the amount of grip that tire has. Ideally all cars would have 25% of their total weight on each corner.  This would give completely neutral handling during cornering, acceleration and braking. Unfortunately it is rarely true apart from exotic mid engine cars where the designer has not had to compromise weight distribution due to other design constraints.

The finished product, aligned, and corner balanced sitting at final ride height.
