I would like to tint the front side Windows on my black FX35 but not sure what would be the best match to the rest of the windows.

The back windows are already tinted from the factory as standard but I would like to tint the front side windows to match the back ones. What would be the recommendation for the best match?

Does anybody know what film tint I should get installed for the FX35? I know Llumar film tint is recommended but not sure what shade and percentage. Would 35% grey/charcoal be very close?

Thanks for your help.
