I have the FIVE:AD kit on my iQ. The rubbing should not be an issue for you. I'm running on AirRunner air suspension and even when I ride at a very low level I don't rub. If you are using lowering springs you won't have a chance to rub at all.
As far as I have found FIVE:AD is the only kit out there right now. There are other kits for the UK and Japanese iQ's but they won't fit our Scion's without some major modifications to the car.
