do you have a bigger wheel size than stock because if you do that may set off your speedo by like 5mph i know my buddies speedo is offset by 5-7mph because of his wheels. so u might be able to get it down to like 15mph over but the second speeding ticket well thats just pure bad luck and as for the tint im pretty sure 4% is illegal at least it is where i live so good luck with those
