I do fabrication on the side so this was a project that was brought to me. Car didnt come with a spare tire. Owner does mild offroading and tows a racecar trailer so he needed a place to have a spare. Before it was on the roof.
I designed this to fit under the factory bumper. I wanted to integrate it as clean as possible and keep it tucked close to the body. It was quite a challenge to work within the constraints of the factory bumper but I made it work. Check it out.
2004 Cayenne Turbo.
Made a plate to fit to a flat surface under the tail light.
Mocked up the spindle.
Alot of careful measuring and trimming on the factory bumper
The swingout arm contours with the edge of the bumper.
Added the latch and the carrier. Also added a second mount connecting spindle to the hitch.
Final result. Unit is very sturdy with essentially zero play.
Nice and tight
