Congrats on your purchase. Since you are in Delhi, I would suggest you get good quality the wind-shield tints from 3M, Llumar or VKool unless you hardly use your car in the sun. In my research, 3M CR70 was the most effective and yet not the most expensive. You may compromise on the side and rear tints, but I think the extra spend on the wind-shield is worth it. It will really help in the summer heat.
