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.
