Nice job getting those with the Cobretti 530! When I finally got them, I had to use the Ryback Firestorm. Believe it or not, I just found out about that alternate route through Construction Site on LABOR DAY. The Air Strike/Revenge events are tough, I would just recommend keeping your speed as high as possible and driving a car you're comfortable drifting with. A lot of those events is just the luck of the air strikes coming at a time when there is plenty of room to maneuver. As far as the Detonator events, well... I think it's the same trick as Power Plant: lots of practice.
Don't give up on the online achievements! If you get a good room, it's fun as heck to play even if you're barely creeping up the ranks. Heck, I was playing in a room full of Form 1 players and got dropped all the way from Form 23 to Form 99, but I learned so much from watching them that it was totally worth it. 2 days later, I ranked myself back up to 10 in about 2-3 hours. Good luck!!
