RS Prestige comes standard with air suspension, DRC (Dynamic Ride Control) is option on the Prestige but is standard on the Performance version that came out with the facelift in 16 (C7.5). The module installs bypassing the factory air and uses a re-pinned can-bus to allow the user (me) to vary the air suspension settings however they’d like. The Auto, Comfort and Dynamic settings can all be pre-set with whatever level of raise or drop up to about 50MM. Once you’ve set the mode you only need to switch to it on the drive select and the suspension will adjust to whatever settings you pre-selected. Those settings aren’t permanent either, they can be changed and re-set at any time. It also has a setting called “Show Mode”, this is what you see in my picture above, that is a lower than drivable drop, about 2 inches, that I only use at shows or when parking the car, ECU sends suspension too low faults if you try and drive that low. Its an awesome little device and I’ve been experimenting with different suspension heights at the track as well to see what gives me the best 60’.
