I'll do front and rear for you this weekend when I get a chance to!
The only speed bumps I have a problem with are the ones into our carpart at work so I now take a detour, but they arent your average speed bump. They cause a problem to anything lower than a Defender!
Its just a case of being mindful of speed bumps and being sensible. I rarely carry passengers in the back seats. On the occasions I have, adults are ok, just take speedbumps slowly.
HTH!
