Can you tell me more about this? What does the "F.S." stand for? Also, is there anything different about this knuckle from the stock Kyosho unit except for that it is alloy? Is this knuckle "Low-Down" or anything like that?
Also it seems many times now, Atomic puts out parts but doesn't go into much detail about what they are or what they do exactly. It would be great if more detail could be put into the description of new parts.
Thanks

I think the "axles" and the tie rod connection part are in ti. I have no idea what FS stands for.
I agree with you on ATM giving to little detail on their products lately.
Looks nice though
FS probably means Front Suspension, although I could be wrong about that. The pictures look like the axle and steering pin may be a different material (SS or Ti possibly). When I get a hold of some, I will post more about them...

-Ride Height lowered by 0.5mm compared to Kyosho stock Knuckles
- F.S. - (Finest Setting) prevents outer front knuckle's Pivot Ball disengagement under hard cornering and chassis roll . (Shim is not included)
The MR-03 knuckles move up and down and also at a slight angle towards the chassis when front suspension is compressed. This is why there is a little pivot ball there while the MR-02 didn't have it.
When outer suspension is fully compressed(as in hard cornering), the pivot ball may come out from the ti-rod resulting in unwanted imprecise movement. Lowered cars are more prone to have this problem.
With the removable pin a racer may add a shim in between to lower it, so that the pivot ball stays inside the ti-rod. See photo for reference.

With shim adjustment(pivot ball stays within)

The problem I have encountered with alu knuckles combined with alu tie rod are binding. The anodicing wears of, and they start to bind. Here this problem looks to be well taken care of.
The adjusting possibilites also looks really great.
