Yes, front end parts on the rear, you want the 4* c hubs to stay on the correct side so they lean back like the fronts.
I screwed long ball studs into the bottom side of bulkheads in the forward hole, no shims. I didn't want to drill the chassis.
You can change the action of the rear steer depending on what hole you mount the links and how low you shim them in the steering knuckles.
(Photo on xray site explains)
ALSO I drilled and tapped the arms so I can mount the shocks out where they need to be
I set the wheels up to be square with the arms, using only the toe blocks to adjust toe.
The car really feels different to drive...It feels like the rear end will snap around but it doesn't. It's actually more like throwing a lasso at the apex and swinging around.

Nice that it works for you. Have you put it on setup station? If so, what toe angle differences do you get? I'm getting 3º when fully compressed (0mm ride height), 1º before wheels leaves the ground, about 1.8º at normal ride height.
And about c-hubs, is there a noticable difference regarding sides? I have put L c-hub on R rear, R c-hub on L rear, it's like "X" front/rear.

So you are gaining toe as the suspension loads? That's not good if so. From the way your links are mounted in the chassis, it looks like the case.
The inner link needs to be higher than the outer to reduce toe when the car loads in the corner.
As for the c hubs, you wouldn't want them leaning forward, the Awesomatix car runs 4* caster in their rear steer
I haven't had mine on a setup station.
However my lap times instantly dropped .5 sec on a 9-10 sec track.

My links are nearly level at ride height, just a slight angle. it's when the suspension loads that the angle pushes the wheel out at the outer wheel.
It does feel a little sketchy accelerating out of the corner but it was easy to adapt to. I don't run much modified, but you would run more rear toe. I'm at 2*, so I actually have toe out in the corner at the outer wheel.
Running less front droop would help keep the car more stable for you?
Here is what I found on the xray site.

Last night I tried out that "active toe" thing on track. I tried both rear steer effects (outer link higher and inner link higher). It was really nice to see that it gives something new, though the track I was at was quite small, slow. Both steer effects are good and drivable, it depends on what you need from your car. With outer link higher car was very calm and predictable, super smooth, not too much steering. Inner link higher - opposite, loads of mid corner steering, twitchy at the exits so smooth throttle control should be in mind.
Next weekend I will be giving another shot, this time in modified at huge carpet track.

Yes, I found that once I got used to the false feeling that the car was spinning out and realized that I could drive it hard into the corner I really killed some hot laps.

great to see you in developing active toe systems for tcxx
here some facts and summary about tcxx update kit / tcxx 2014 kit and a german report about these kit.
