Payday is coming up and that means modding time for the car!

Decided on tints for the back 3 windows, been shopping around and found somewhere 5 minutes away from me for £80, was also recommended by some mates.

Just a quick question on what light percentage I should have? I was thinking around 80%.

Also what is visibility like with them really dark, is reversing easy enough at night?

A few pictures would be nice too for some examples too thanks
