D2 Racing D-BM-64-VACF-20D2-ACK03 RS Coilovers with Front Air Cups and Gold Tankless Control System

The D2 Racing D-BM-64-VACF-20D2-ACK03 combines the performance of D2's RS coilover platform with the on-demand height adjustment of an integrated front air cup system. Designed for the 1996–2002 BMW Z3 and 2006–2008 BMW Z4, this kit delivers the handling characteristics of a traditional coilover with the added flexibility of air-assisted lift at the front axle.

The front air cups are machined from CNC billet aluminum and feature a double-sealed piston design. With the press of a button, the front of the vehicle can be raised up to 2.0 inches in seconds, allowing lowered vehicles to navigate speed bumps, steep driveway inclines and declines, and trailer approaches without scraping or damage.

Gold Tankless Control System:

This kit features D2's Gold Tankless configuration, which eliminates the air reservoir tank and upgrades to a Viair 444C compressor — making it the ideal solution for builds where underhood or undercarriage space is at a premium. The system uses a 3-way IMI electronic valve controlled by an LED backlit switch that integrates cleanly into the vehicle's dashboard. Pressing the switch raises the vehicle to full height; pressing again releases air and returns the vehicle to its lowered stance.

What's Included:

• (2) Front Air Cups — CNC billet aluminum, double-sealed piston
• Viair 444C Compressor (tankless upgrade)
• IMI 3-Way Electronic Valve
• LED Backlit Control Switch
• All necessary fittings, relays, and air lines

Key Features:

• Compatible with D2 RS coilovers (front application)
• Up to 2.0-inch lift on demand
• Tankless design saves space compared to standard electronic kits
• Viair 444C compressor for reliable, high-output air delivery
• Simple single-button operation with LED-lit dash switch
• CNC machined billet aluminum construction for durability and precision fit

The D2 Racing RS Air Cup Kit is purpose-built for enthusiasts who want a slammed daily driving stance without sacrificing practicality. The tankless Gold system provides a clean, compact installation while delivering fast, repeatable lift performance on the front axle.
