I'm sure there is a way but I doubt it'll ever be secure.

I have the sliders on mine and yes it would bother me if I left it anywhere. Hence I don't now.

But think how hot it will get in the car if you don't have sliders as you obviously will be removing all the electric windows or winding mechanisms.

Trust me it gets a bit warm in the car if you do track days

You'll just have to weigh it up. Whether you will end up leaving the car anywhere or to go for the windows with non sliders. That's if you haven't already bought them. The sliders rattle like fuck if you don't secure them
