I've just fitted one of these and it gives steering geometry like the 511x.. Very nice

Ah, good to know. I have one on order.

Does it give more turn in? Badly needs it.

I've run it, and it's good and bad news:

1. The bad: it doesn't solve the lack of outer lock. It is better than kit standard but gives less lock than a flipped or JT models link I think at least.

2. The good: it is more linear, and the car feels a bit more together with it in. On my tight indoor local track I didn't really feel the lack of lock (though it was practice so maybe I'll notice racing) and on bigger outdoor tracks it is fine.

To maximise lock I'd consider:
1. Keep it shimmed! After a couple runs I was able to add shimming to the two upright shafts to decrease play.
2. Tighten everything as much as possible, including bridge screws. I connect the servo last and found the steering still nice and free when doing this, but less play means less lost outside lock!
3. You can dremel down the Ali castor blocks then use a screw to set max lock on each side, this gives even more inner lock and therefore allows more outer....I haven't tried this yet! I also think binding may become an issue on the driveshaft if done too far!

I ran this set up at the weekend on astro and the car felt really good. It seemed less twitchy than the flipped JT bridge. I spaced the ball studs forward by 3mm which gave a little extra outside lock
