I finally had the time to test the "active rear suspension" conversion. You know I was sceptical, but it works! On my first run I could already better my personal lap record by two hundreth from 12.64s to 12.62s. It makes the car turn better without giving oversteer. Combined with some small setup changes (long rear camber links and RSD TC6.2 springs white in the rear and light blue in front), I could reduce my personal best to 12.39s.
So from my point of view I can recommend the conversion.
My 6.2 ran 17.5t blinky with VTEC G32 tires on a medium grip asphalt track.

Toe in on the setup board is 1.5*. With full deflected spring it reduces to 0.5* on the outside wheel.

Did you notice that XRay has been working on this idea too? It looks like they will have a conversion out pretty soon for their cars. I'd be interested to see if this starts to become a trend in TC design going forward.

@thecaptain: I had 1.5* before which gave the car a little too much oversteer for my liking.

@YoDog: I recognized Xray and Serpent working on it and thought I give it a try on my 6.2 as I already had real rear steering on my TC6 4WS and liked some of its functions. But on the 4WS the rear steering was too strong. The bumpsteer version seems to give the right amount of toe change and is not asking for a whole new setup

I did a study thesis on some Anti-squat/kick-up and just want to mention, that if the car has bumpsteer (active steering is a marketing phrase) on the rear and the steering has a positive offset (german: Lenkrollradius) the Anti-squat on the rear is affected quite a lot.
If set up to generate Toe-in on bump then you increase the anti-squat effect, if the pickup points of the steering linkage are set up to get toe-out on bump then you decrease the anti-squat effect or even create pro-lift.

@wtcc: Do you really set up the bumpsteer to toe-out on bump ? Did you already try the opposite?

If you want less drag on the straight and still the right grip on the rear in corners, i would set up the pickup points to get toe-in on bump (mehr Vorspur beim Einfedern).

Alright thank you. Looking forward to try that once I get the rest of my car put back together. Please post any more of your findings.

Thanks for the explanation Worst87! I am driving a pro squat setup in the rear. The rear steering in my understanding should have the opposite direction than the front to help the car turning (not to take grip away). By having the rear steering in the same direction it would handicap the car driving a circle.
But car physics are complex and your explanation seems reasonable, too.

I haven't tried it the other way, yet. So I can't say how it works. Just one way to find out. Like Germans say:"Probieren geht über studieren."

If you're talking about the TEK chassis with the split blocks, it doesn't look like it, remember that was designed for the 6.1 motor mount which is completely different, and it looks to use the single bellcrank vs the dual on the 6.2
