i'd too also go 20% its dark enough to not be clearly seen but not draw too attention from cops or make it difficult to see out of at night. i have had in the past 10% 18% 20% and 35%. i'd never go 35% again! waste of money. not even dark! 10% is clear as day illegal and 18+20% was perfect.

i crashed my last car wrote it off and it had 10% tint i got my full pay out no tint questions asked. it is alot harder to see out of at night on dark streets but with street lights and day it is fine.

pic of 10 %



as you can see they are pitch black

i'll have to take pics of my now 20% tint job if you want but i am alot happier with the 20%
