D2 Racing D-BM-70-VACF-20D2-ACK03 RS Coilovers with Front Air Cups and Gold Tankless Control System

The D2 Racing D-BM-70-VACF-20D2-ACK03 combines the performance of RS coilovers with the convenience of an air cup lift system, delivering a hybrid suspension solution for BMW 3-Series and 4-Series RWD owners who refuse to compromise. Designed to integrate directly with D2 RS coilovers at the front axle, this kit provides on-demand height adjustment without sacrificing the handling characteristics and reliability that coilover enthusiasts expect.

The air cups are CNC-machined from billet aluminum and feature a double-sealed piston design capable of raising the vehicle up to 2.0 inches at the push of a button — giving lowered vehicles the clearance needed to navigate speed bumps, steep driveway inclines and declines, and trailer ramps with ease.

Gold Tankless Control System:

This kit features the Gold Tankless ("Tankless") configuration, which eliminates the air reservoir tank entirely and upgrades to a Viair 444C compressor — making it ideal for builds where underhood or trunk space is at a premium. Control is handled via a 3-way IMI electronic valve paired with an LED backlit switch that mounts cleanly into the vehicle's dash. Pressing the button raises the vehicle to full lift height; pressing it again returns the suspension to standard ride height.

Kit Includes:

• (2) Billet Aluminum Air Cups — CNC-machined with double-sealed piston, up to 2.0" of lift
• Viair 444C Compressor — high-output, tankless-compatible unit
• IMI 3-Way Electronic Valve — precise air management
• LED Backlit Dash Switch — easy single-button lift/lower operation
• All necessary fittings, relays, and air lines for a complete installation

Designed for compatibility with D2 RS Coilovers on the front axle, this kit is the perfect upgrade for enthusiasts who want the daily drivability of air lift technology integrated into a proven performance coilover platform.
