Schelle Type 1 steering arms review

I got a tuning part in the mail to help with the 180 degree turns we have at my local track.  These are Schelle Racing Type 1 steering arms, and add a fair amount of Ackermann gain when turning, especially at full lock.  They pull the steering ballstud in a little bit and also forward a little bit, you can see the difference in the picture above.
I did some testing today, and they definitely help you finish the turn mid and corner exit.  They are quite aggressive, enough to the point where I was thinking about lowering my roll rear center a bit, but I like them basically as a bolt-on.  The geometry seems pretty good, stock Ackermann must be a little bit off, as even Associated makes a pair of +1 Ackermann steering arms.  Stock geometry induces a little bit of push in my experience.
Recommended if you need more mid and exit corner rotation in 180′s.  They’re cheap to try at $8.
