Bilstein B16 (iRC) suspension kits feature ride height adjustability with standalone electronically adjustable dampers in an OE quality direct fit package. This suspension kit allows the driver to electronically select between a Comfort or Sport setting via the iRC smartphone app and an in cabin mounted button. The iRC app allows the user to fine tune the parameters which controls the switching from Comfort to Sport on the electronic dampers. An accelerometer built into the control module provides the app with a graph of the g-forces while driving. This graph allows a user to choose the exact moment the electronic dampers will activate to provide an active suspension experience! Switching between Comfort and Sport modes can still be operated manually with the Bilstein Sport button. B16 (iRC) suspension kits are made in Germany and feature technology tested on the famed Nürburgring. Compatible with iOS only.
