Yeah Racing Aluminum CNC Magnetic Invisible Body Mount (Blue)

Great solution if you don't want to cut holes in your body for posts. Installed on my MST RMX 2.0 S15 and works great. Magnets are super strong! I can pick up the car by the shell and it won't come apart! I will be ordering more of these for other projects! PS they are sold in a pair so make sure to add 2 to your cart!

Purchased these so I could have a hole-less lexan body for my 1/10 Rally car. I appreciate that the height, angle, and distance from the mounting pole is all adjustable. The angle comes is needed for the hood of touring cars.
The magnets are strong, I stick them to the body using 3M VHB tape, which seems strong enough to hold against the magnetic pull.
The one downside is the screws: I don't feel like they have much friction in the thread, and I'm worried that they'll loosen at some point, so I've added a little Loctite. At least if the philips-head screws loosen, the arms will not travel any farther upward so it won't result in body rattling. I put body shell clips on the mount pole above and below, locking in the mount so if the grub screws loosen, the mount won't move up or down.

I think this should hold up nicely since my rally car won't be taking any big jumps or potholes, but I would not recommend it for stadium/short course/monster trucks.
