Suspension Combos

I Just lowered the rear on mine with the Roush rear spring kit. The ride is a little stiffer but feels better overall as it eliminates a bit of the rear floatiness the car has. A swaybar would probably plant the thing down.
 
Now that I have all the parts on order to satrt my suspension I have one more question.

I live here in Orange county California, does any one know of some good performance shops around the oc?
