chino: If you look carefully at the 1st pic, you'll see my tint strip. The guy who did it offered to tint the whole front window with 50%, but I wanted to keep perfect visibility in the front.
aerophlo: I know several people who have done 5% & they all agree it's too dark. It might look great from the outside, but it's almost impossible to see out at night.
TigrMsP: My friend lives in GA & he got 11% on his black WRX. Of course that looked great, but I think 20% is the best compromise between looks & safety. This is my 3rd car & I've had tint on every one...the last 2 have been 20% & I've been very happy with the results.
