15% rear of the driver, 27 or 28% next to the driver, and nothing below the as1 line but above the as1 I don't know of any restriction. I have had 15% platinum plus ( the mirrored stuff ) and a layer of %15 charcoal, for 2 years on my crx and no tickets yet, your best bet is to just roll down both front windows if your pulled over, but never heard of anyone getting pulled over strictly for dark tint. I will be running the same setup on my civic hb but I will also be adding 30% to the windsheild and then a 5% sun strip, I have seen the sun strip with the windsheild tint and it helps to disguise the tint. 99.9% of the cops around here don't give a shit about tint. there too busy giving you shit about a D.O.T. 50 state legal exhaust system.
