VDCAUDIA49401 is the Vertical Doors, Inc. vehicle-specific Vertical Door Conversion Kit for the 1994-2001 Audi A4 sedan. The system retains the original doors and creates the traditional VDI movement: each door opens outward first, then raises vertically. This conversion is also commonly described as a Lambo door kit or scissor door kit.
Give the B5 Audi A4 a More Dramatic First Impression
The clean proportions of the first-generation A4 make the upward door motion especially noticeable without changing the car's understated character.
The B5 sedan's compact doors and straight beltline keep the conversion visually clean. With the doors closed, the A4 keeps its familiar understated shape; with the doors raised, the car takes on a completely different parked presence.
The vehicle-specific VDCAUDIA49401 system is listed for the 1994-2001 Audi A4 application described on this page. It retains the original doors and uses a vehicle-specific hinge system instead of a universal weld-on conversion.
Keep the classic B5 profile and make the entrance the detail people remember.

1994-2001 Audi A4 Fitment
This kit is made for the 1994-2001 Audi A4 sedan range listed by VDI. The B5 family was also sold as an Avant, so confirm that the vehicle is a sedan before ordering.
Audi introduced the B5 A4 sedan in 1994, but North American model-year availability began later. Owners of early-production or non-North-American cars should confirm the exact year and body configuration with VDI.
Important fitment note: The trim, model, package, engine, drivetrain, and platform names on this page help identify vehicles sold within the listed range. They do not confirm that every configuration automatically uses the same Vertical Doors hinge application. Confirm the model year, exact body style, and door configuration before ordering when fitment is uncertain.
Contact Vertical Doors, Inc. first if the vehicle has aftermarket fenders, widebody components, custom bodywork, previous collision repair, a body conversion, replacement hinges, or another modification near the hinge and fender area.

How the Vertical Door Conversion Works
After installation, open the A4 door outward until it reaches the hinge system's stopping point, then raise it vertically. The gas shock assists during the upward movement.
This outward-first movement allows normal entry and exit before the door is raised. Proper installation and adjustment are essential for door alignment, latch operation, wiring clearance, surrounding panel clearance, and consistent opening and closing.
Installation Requirements
The VDI hinge system is designed around the vehicle's factory hinge area. Bolt-on describes the vehicle-specific mounting design; it does not mean the installation is modification-free. Installation commonly requires body-panel removal, non-visible trimming or clearance work, wiring management, and careful final alignment.
Before loosening or removing the original hinges, use 2-inch painter's tape to mark the door's factory alignment. Place tape across the door and adjacent body at several reference points, including near the hinges and firewall, then draw matching alignment lines across the tape. These marks help preserve the door's original horizontal and vertical position during installation.
- Support the door safely throughout the installation.
- Follow the supplied instructions for hinge stops, gas-shock installation, wiring, and panel clearance.
- Check the latch, weather sealing, wiring, and surrounding body panels before road use.
If you are not experienced with door alignment, drilling or tapping where applicable, body-panel removal, trimming, and wiring clearance, use a qualified automotive customization or body shop.

Frequently Asked Questions
Is VDCAUDIA49401 a universal Lambo door kit?
No. VDCAUDIA49401 is a vehicle-specific Vertical Doors, Inc. application for the listed 1994-2001 Audi A4. It is not a universal weld-on hinge system.
Does VDCAUDIA49401 fit every Audi A4 trim and body style?
No blanket all-trim or all-body claim should be made from the model name alone. The trim and configuration names on this page are identification context. Match the exact model year, body style, and door configuration to the VDI listing and contact VDI when anything is uncertain.
What chassis or platform is associated with this A4 range?
The vehicle history for this listing is associated with Audi B5 (Type 8D). Platform information helps identify the vehicle but does not prove that another model on the same architecture uses this kit.
Does the conversion replace the factory Audi doors?
No. The original doors are retained. The Vertical Doors hinge assemblies and gas shocks change how the doors move.
How do the converted doors open?
The doors open outward first to the hinge system's stopping point. They can then be raised vertically with assistance from the gas shocks.
Is trimming or adjustment required?
Yes. Installation commonly requires body-panel removal, non-visible trimming or clearance work, wiring management, hinge adjustment, and careful final door alignment.
Can I install VDCAUDIA49401 myself?
A mechanically experienced person with the proper tools, safe workspace, patience, and door-alignment experience may install the kit. Use a qualified installer if you are not comfortable with body-panel removal, trimming, wiring clearance, hinge adjustment, and final alignment.
Can the vehicle be returned to factory hinges?
The original doors and factory hinges can generally be reinstalled, but trimming, drilling, tapping, or other application-specific work may need repair if an exact factory restoration is required.
Can Vertical Doors, Inc. help after I buy the kit?
Yes. VDI provides fitment, installation, adjustment, operation, replacement-parts, and product support before, during, and after the purchase.

“Just an awesome experience today at Vertical Doors! This company takes care of their customers! Thank you for making our son's day. You all rock!”
“Vertical Doors Inc is the original name in the game when it comes to Lambo Doors. I had the pleasure of buying their kit for my 2014 C7. I highly recommend getting the install done by them as the process is quite extensive! They had me in and out in one day. No door gaps to speak of and the hinges feel smooth and strong. Don't try doing the kit at home, let the pros do it for you. They also gave me a deal on some beautiful true carbon fiber skirts made in house! Shout out to their sibling company California SuperCoupes.”
“I was having trouble with my C8 Door after a terrible attempt at install by another company (Eikon Motorsports). I called Vertical Doors and Danny was able to be a hugeeeee help. He got me in right away, told me exactly what the problem was, knowledgeable, extremely responsive, and communicated with me the whole way through. I cant say enough of the team there. I wish I would have come to them in the first place.”
Ordered my 2018 SS Camaro kit during the COVID crises. The team worked hard to get my kit to me during this critical time. I am so pleased with the new look. It took my Camaro to a new level. Great craftsmanship and best kit anywhere. - TJ from Florida
