Zip-ties, duct tape, and bailing wire are the most common MacGyver items in a rally car. When a rally is in town, we usually have more spare zip-ties then the local Super Walmart. Zip-ties are a rally essential, but you need to pickup an essential tool for installing them: A pair of flush cutters. Plastic knives can be pretty sharp and poorly trimmed zip-ties can be sharper! I’ve seen and had some pretty bad lacerations from the remaining 1/4″ of zip tie that was bevel cut into a sharp spike by standard wire cutters. I now avoid using them on the roll cage and tuck the zip-tie head as far away as possible. Don’t have a flush cutter handy? In a pinch you can use a lighter to soften and melt the end.
