How to Reduce Strap Noise When Transporting a Kayak?

Hey everyone,

I recently bought some foam racks to transport my new kayak on my car's roof. The first trip went smoothly, except for one major issue—the straps made an incredibly loud noise inside the car while driving. It was almost unbearable!

Does anyone have a good solution for this? Do the straps need to be twisted in a certain way, or is there another trick to stop the noise? I'd really appreciate any advice!

Thanks in advance!
