Vertical Mount Collapsible Spare Tire, Like a 944 Options

[7TPorsh]

I'm going to be adding an oil cooler, fuel pump and battery up in the frunk. Guessing by 165SR/15 spare is going to have to be sacrificed.

I am thinking of a vertical mount on the bulkhead with a 13" or 14" wheel and a collapsible tire...a smaller version of what 944's have. Or a skinny spare.

Ideally something like a 13x5.5/6 or 14" wheel. Are there any wheels out there, steel or otherwise' that have a 4x130 and are narrow 13 or 14"? Not concerned too much with looks.

I am running 15x7 Panasports with 195/55 on the car. I'm not near the car so not sure how much vertical space there is in the frunk.

Pictures of solutions for tire and/or battery and oil cooler frunk installs much appreciated. thx
