i just did a really fast look up on the laws in CA.

Windshield - Non-reflective tint is allowed on the top 4 inches of the windshield.
Front Side Windows - Must allow more than 70% of light in. (one place said 85%)
Back Side Windows - Any darkness can be used.
Rear Window - Any darkness can be used.

so would that mean that the ligal limit for front windows in california be 30%?
