Securing toolkit properly in frunk

The straps will snap before the rivets break. They are made from constituted leather and don't hold up very well.

In answer to your question, I pack mine out with a cloth as you suggest.

 

I have the same issue... I put as many of the booklets into that pouch as possible to make it be its fattest. It doesn't slide out of the strap but it still kinda tries to lay down... I'll add a microfiber in there as well and see if that holds it more upright without stressing the straps too too much.

 

I think Ferrari uses these leather straps to have that old school charm type of look but honestly I can't stand them. I take out the tire goop stuff, It and the tools are still in the clear wrapper. I do have 2 or 3 microfiber towels help to take up room right now. I wish these straps were more modern like a ski boot strap or at least a nylon velcro strap as the leather Ferrari uses is not strong like a belt for your pants...real cheap feeling leather for cars that cost this much.
