If so, could this be a path for West Coast chasses with fixed axles / no tensioners?
GT2 is stronger than HTD by a large margin. The Gates precision and light duty manual is a really good read, though it can be a bit boring.

For something as critical as a drivetrain, I'd be hesitant to run them untensioned. It's hard to get everything perfect to get the perfect tension. You also want a pretty significant preload to prevent ratcheting.

We are going to be running 15mm GT3. We've run 9mm GT2 and 9mm GT3, and they are on the edge of surviving a season. (3.5" wheel, 24 tooth pulley).

We are pretty excited about the pulleys!
