I've owned three Miata's before my S2000 and all three has adjustable soft top latches. Open the latch, turn a tightening nut, and the soft top is secure again. My commute takes me over some ruff roads and my top seems to continually come loose. I was wondering if anybody makes replacement soft top latches that are adjustable. Thanks!

 

Some people have installed hard top latches. They're not adjustable but the spring mechanism is much tighter.
