I highly doubt you need to wait for a setup made specifically for the iM. If you go to any shop that specializes in suspension applications like this they'll be able to do it for you, you just have to be prepared to spend at least $3500+. Expensive but worth it as long as the setup is QUALITY.
Buying a cup kit for your coil setup is the ultimate setup, but very costly. When I was checking for cup kits before it was $2k for a front pair and another $2k for the rears, combine that with a good coilover setup and it's quite a bit of money.
On the bright side you can go a really low height and when you reach a speed bump, raise the car for a little bit, go over, and drop back down.
