im pretty sure that the front door windows by law are supposed to be completly clear but
you can go as dark as u like from the b pillar back etc
in my experience you can have a super light tint on the front door windows
so long as u dont take the mick u should be ok ive never had any
probs with mine - anyway i think a light tint looks more classy, limo black all round looks chavy i think and is asking to be pulled
