Amuro,
Mine are a little loose, but not really that much. I'm thinking that making them tighter might make it harder for them to move, should the suspension compress enough to actuate them. If you do make them tighter post the results.

As for the camo fabric. I ended up dying it with a green color. Didn't do much but darken it up some, but boy did it distort the cloth. Forgot what happens to that fabric when it gets wet.

It actually looks really good, I think. Gives it a more natural look in a way.
