Something a little different for the sake of testing on low grip tracks here in Australia. We've decided to install the Awesomatix ZA fwd zero ackerman steering arm set to the A800rr. The ZA servo mount arm is roughly the same length bar the final positions of the inboard ballends on the ZA setup being slightly forward by a mm or so. The servo horn linkage position that connects to AM180FX-LA seems to be the exact same position as the steering link position on the FSS servo mount set.

When the ZA set is installed onto the A800rr with stock steering arms (AM14LS) the outside tyre has 3 degrees more steering while the inside wheel has 1 degree less. This will give more initial steering feel and steering input reactivity when compared to the standard FSS setup. Here in Australia, our tracks tend to be lower grip, tight tracks so extra angle can help you get more initial reactivity on initial turn in.

You could attempt to try using the ZA steering arms, but I didn't bother for now.
Too much steering angle on higher grip surfaces makes the car hard to drive or in extreme situations, traction rolling. It also loads up the tyre and works it harder as the angle at peak steering is greater on turn in, so this is really only a mod that would benefit tight tracks and or low grip tight tracks.

The aim is to have the car steer via rear end setup but allow the front to have more angle if needed simply via steering input and radio setup when it's needed.

This mod might also be helpful when running long top arms on low to medium grip tracks. Long arms remove peak grip but extend the overall grip curve meaning initial steering input can sometimes feel a bit slower when using longer arms, getting some extra degrees of steering on the loaded side when turning in can give back that sharp turn in feeling. You can also get this via a higher servo link angle at the servo horn end. Getting your steering angle right so you don't slow the car down too much due to scrub entering a corner while getting the turn in you need via setup is all a balance. This is just a wild thing to try after you've tried all your other setup options FIRST.
