Hey Joon, we purchased the
base kit from Filmtools and have been very pleased with it so far. And believe me, we used it extensively, including mounting it on the hood of a car for interior shots coming down a steep and curving mountain road and also when chasing another car, one that was drifting (but not on the drifting car itself).
The kit is really simple and allows you to build on it in the future. Each suction cup is supposed to be weighted for 70 lbs but as mentioned above, should be halved when mounted vertically. These are industrial strength suction cups.
Some things to keep in mind though:
Clean the surface of the car you are mounting it to and keep the suction cups clean as well.
Always check and lock down all arms, cups, etc between every take. Bring allen key wrenches to tighten everything. Secure the mount and camera with straps/bungie cords.
Give yourself some time for setup. The mount is not the fastest to setup and secure, especially if you use the cheeseplate as the base. A small camera angle change can take several minutes. Shooting
Taxi Driver type shots of the car for example can take a while as you unmount, remount, unsecure, secure etc.
Before a car mount shoot, might want to check that your insurance policy is still effective and solid.
And test! Before mounting your camera we mounted close to 25 lbs of bottled water in a bag, which we strapped to the car mount. We then drove around town and tried our best to test the limits of the mount, braking hard, making bad turns, etc. We had a good time and received quite a bit of strange looks from passerby - "What in the world is that?"
Anyway, we were satisfied with the mount and have enjoyed using it without problem so far. I will see if we can post our drifting footage soon.
