Something similar exists for my cars. Subframe "lockdown" it is called, but it makes the ride a bit harsher. The hatch I just picked up had a few nifty options installed:
My sedan has very little suspension wise that hasn't been touched. Most bushings replaced with SuperPro poly ones, swaybars and endlinks, 12 way adjustable coilovers designed by my friend's shop specifically for this car, AP brakes w/2 piece DBA rotors, sst lines, etc...
