Hello i know it will work... I I tested it at old Arma Dayz Origins they got nice feature. Put PLANKS of WOOD/METAL on rears,back and tops of the car. So you will gather materials for "TUNNING" your own vehicle.
Since my english skills are bad there is a video i know many of us remebering it it was awesome: http://www.dayztv.com/video/dayz-origins-18-update-preview/
To be not overpowered there should be health on those items like Wood will needs about 5 shots to break since you can get wood everywhere.
Thank You !
