VDCALFA4C13 is the Vertical Doors, Inc. vehicle-specific Vertical Door Conversion Kit listed for the 2013-2020 Alfa Romeo 4C. The system retains the original front doors. Each converted door opens outward first for normal entry and exit, then raises vertically.
Vertical Door Movement for the Alfa Romeo 4C
The Alfa Romeo 4C is a compact, mid-engine two-seat sports car built around a carbon-fiber monocoque. Its short body, forward cabin, and sculpted rear proportions already make the 4C visually distinctive. A genuine VDI conversion adds vertical door movement while retaining the original door shells and interior panels.
With the doors raised, the conversion complements the 4C's compact profile without replacing the original doors. Correct vehicle identification and careful installation remain essential, especially because the 4C range includes both Coupe and Spider body configurations.

2013-2020 Alfa Romeo 4C Fitment
VDI lists part number VDCALFA4C13 for 2013-2020 Alfa Romeo 4C models. Alfa Romeo produced the 4C in Coupe and Spider body configurations, but the current VDI listing does not document those two bodies separately. Confirm your exact model year and Coupe or Spider body style with Vertical Doors, Inc. before ordering.
Contact VDI before purchasing if the vehicle has modified fenders, aftermarket bodywork, prior collision repair, a previous hinge conversion, or another modification near the front hinge and fender area.

How the Vertical Door Conversion Works
After installation, open the door outward until it reaches the hinge system's stopping point, then raise it vertically. The gas shock assists during the upward movement. Correct adjustment is essential for door alignment, latch operation, wiring clearance, weather sealing, and surrounding-panel clearance.
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 installation.
- Follow the supplied instructions for hinge stops, shocks, 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, body-panel removal, trimming, wiring clearance, and hinge adjustment, use a qualified automotive customization or body shop.
Before You Order

- Review the current shipping policy and refund policy before purchasing.
- Call Vertical Doors, Inc. at 951-245-8669 when fitment is uncertain.
Frequently Asked Questions
Is VDCALFA4C13 a universal Lambo door kit?
No. VDCALFA4C13 is a vehicle-specific VDI application listed for the 2013-2020 Alfa Romeo 4C. It is not a universal weld-on hinge system.
Does this kit fit both the Alfa Romeo 4C Coupe and Spider?
The VDI catalog lists the 2013-2020 Alfa Romeo 4C range, but the current product listing does not separately confirm Coupe and Spider compatibility. Contact VDI with the model year and body style before ordering.
Does the kit replace the original doors?
No. The original doors are retained. The VDI hinge assemblies and gas shocks change how the doors move.
Does bolt-on mean no trimming or adjustment is required?
No. Bolt-on refers to the vehicle-specific mounting design. Application-specific trimming, clearance work, wiring management, and final door alignment can still be required.
Can I install this kit myself?
An experienced automotive installer with the correct tools, workspace, and door-alignment knowledge may complete the installation. Use a qualified installer if you are not comfortable with panel removal, trimming, wiring clearance, and final adjustment.
“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
