because 30% front+back windscreen and 50% for side window..still within tolerance...
but mine just cheap tint rm250 at brothers....wakakakakakak....
better to get good quality tint...u'll notice the diff during burning hot sun in broad daylight....
cooler ambient temp. without being too dark...
30% is for front, back can be 50%.....
Recently see a lot of cars tint got polka dot air bubbles. Those must be very cheap tint. I wonder how they drive as really hard to see.....
