It depends on what you're doing with them--our accelerometer is way off to the side, but the only thing we use it for is traction control and if we have enough traction to turn fast enough to affect the reading, we don't really need the traction control.

Another consideration is electrical noise--avoid putting it next to something that spits out a lot of EM(like the motors or PDU), as this can really noise up your readings.
