IMU swap

I have BNO with wires to MMA slot on PCBv2 but because box moves its unstable. Thinking about moving it outside of box and fixing it to frame.

With BNO085 because magnetometer is not used it can be placed anywhere.

Is there any benefit to putting IMU or IMU module closer to antenna and under it (to middle of tractor)?

Main advantage of IMU module is future proofing if higher IMU speed can be used?

For Chinese and other 3.3v IMU should logic level shifter be used for IMU module, on PCB its behind 330omh resistor or is it ok to connect it directly as in wiring?
