For E46 M3 owners chasing fast-road compliance, track-day adjustability or show-car stance-without welding, coding or compromise. This is the full AirRex V1 system, built for N54/N55-era expectations but tuned and proven on the E46’s unique geometry.

• E46-specific: Front struts use OEM top mounts and lower control arm pickup; rear units clear ZHP subframes and M3 trailing arms-no spacers, no trimming
• Stage 2-ready: Viair 444C compressor + 3-gallon moisture-trap tank handles repeated drop-and-rise cycles at track days or car shows
• Pressure-based control: Wireless touchscreen controller with All Up/All Down, individual corner presets, and Rise-on-Start-no OBD dongles or app dependency
• Fast-road damping: 12-click monotube front/rear dampers, height-adjustable bodies, triple-bellow fronts and slim double-bellow rears for arch clearance
