Simple instructions.
Raise rear of vehicle and support on jack stands. Be sure that the rear tires are off the ground.
Support rear twist beam.
Remove both lower shock mounting bolts.
Slowly lower twist beam, making sure that no lines or wires are stressed or damaged.
Remove rear springs from perches.
Clean out lower spring pocket on twist beam.
Place ZZP sway bar mounting plates in the spring pocket, studs down through holes in pocket.
attach sway bar to the studs on the mounting plates, the plate and bar will sandwich the spring pocket.
Be sure the bar is centered as much as possible and tighten fasteners.
Re-install springs
Raise twist beam and re-install lower shock bolts.
Raise vehicle and remove jack stands.
Lower vehicle.
Enjoy the drive.

Y do U keep touching ur ballz?
Anybody have thoughts on there not being any mounting for the bar on the straight part like a sway bar? Normally those mounts are there to allow the bar to only twist from the ends moving vertically. Having it just solidly mounted on both ends without the "middle mounts" makes me think the bar is going to have bending stresses on it rather than torsion.
I haven't seen it installed so maybe I'm missing something though. Anybody have any pictures?

Still not sure about it. I'd be interested to see how these things do with some time/miles.

Keep in mind that I have the Eibach pro kit (stock LT 15" shocks and struts for now), BNR front (adjustable whore bar), DDM insert, and ZZP rear bolt in sway bar. My overall opinion for how my car is set up for autocross is that cold tires result in a very tail happy car, even when playing with tire pressure. Once the tires are up to temp this setup is capable of performing better than I am. For street driving it allows for a lot of fun without any noticeable over or understeer when on a 225/45/17 street tire, but I do not really get close to the limit in daily driving. with the stock 15" wheel/tire set up it will tend to oversteer a little if really pushed, but once again I stay away from that limit most of the time.

Im not really concerned with class only occasionally hit track. Pretty much building to suit my wants and nothing else lol. My coilovers are set at 25 (32 being hardest) front and back. Im def going to move it down to about 15, just too rough on Chicago streets. I have almost no body roll now though 
I have the Eibach pro kit, both aftermarket sway bars (no brace) and 235/45 summer shoes. I feel the exact same way about my RS.
