Ha ha I like 240z-fan's answer. I agree with his hood gap theory!

Nicely put. Only wish I'd thought of it...

If you want to install it the correct way (assuming a sqaure chassis):

1. Level the car side-to-side and fore-aft on a set of slip plates and corner weight scales.

2. Set the ride height and corner weights.

3. Using a camber gauge and a level, set each wheel perpendicular to the ground and the chassis.

4. Check the car level, ride height, and corner weights again. Adjust.

5. Install the STB and adjust it so its tight but not affecting wheel camber, ride height, and/or corner weights.

A STB is supposed to maintain chassis dimensions so that suspension geometry remains as consistent as possible. Without any data, just tensioning a STB until it "feels right" is most likely distorting the chassis.
