So, for example, if you have a 6 wheel robot with front and back wheels fixed, but a passive suspension on the middle wheel, you might me fine - when you're starting up the incline (or finishing coming down) the suspension would push the middle wheel down to maintain contact - at the top, it would let the middle wheel ride up to give better stability/contact - but the key is that, at all times on level ground the bumper remains within the bumper zone. That's pretty easy to prove with a passive suspension, and may be allowed

What if the suspension is active?In that case, you may have an issue, as the suspension could push out, increasing the height of the bumpers outside of the bumper zone.

What if the suspension is on all wheels? Then you might also have a problem, as any adjustment could cause your bumpers to leave the bumper zone.

I would recommend asking the GDC about the legality of suspension on wheels and how that comes into affect with regards to traveling over the bump and the bumper zone before getting too far in your design process.
suspension would not change whether the bumpers are in the bumper zone or not, because any adjustments are likely going to be small, and when they are absorbing shock, the drive plane remains the same. although, i'd ask the GDC, just to be sure
