Caster shims
They adjust the caster. Move shims behind the arms for less caster.

I know how it works with the C-Hubs, but I think I'm failing to realize how sliding the front upper arm front or to the rear on that hinge pin what it actually does.
I know you can increase or decrease the angle via the pills but still confused about the actual back and forth position on that hinge pin, where those caster shims go. They don't really explain it in the manual and haven't really gotten a clear cut answer searching.
Orrr maybe Im overthinking this and its right in front of me lol.

Well, yes, that's the obvious answer

When you move the upper arm forward you are making the steering knuckle more upright thereby decreasing caster which will make the car more reactive to steering angle and less stable over bumps. Moving the upper are back will increase caster, decreasing steering a little bit but increasing stability. This is the same concept as changing caster inserts for the hinge pin at the bottom of a C-hub.

The angle of the upper arm changes the "active" caster. Most people cannot explain it, so I recommend you keep them equal front to back.
The arm position, front to rear changes the actual caster.
The pills for the lower arm are for kickup.

Tried the new AE angle drilled pistons, they seem really nice, and made the car much better on a bumpy track. I was running the Kyosho angle drilled 8X1.3 versions previously and, performance seems identical to those. It is nice having the 1.2 angle drilled option as well from AE, but I have not tried them yet, I will next time out..
Also I just ordered the new under drive rear ring and pinion. Going to give that a try.
I've been running the car at Revelation here in So Cal one night a week the last few weeks just trying to dial it in and learn what the car likes. It is getting closer, but I end up spending time adjusting for the large temp swings that tighten the car up in the evenings. I have a couple sets of shocks and have the day to night setups pretty close. The problem is that the track is rougher every week, so my night setup turns into my daytime setup for the next week, and I have to come up with a softer night setup.
I'm really liking the car overall. The car is really durable and easy to work on. I was going to run DNC, I raced in the first 3 of them in Hemet and haven't since, but I have a 24 hours on Lemons race in AZ that same weekend.

I really liked running the 42/12 gears at Rev. That surface can get pretty rough and the under drive gears help keep me from getting out of control as quickly.. especially when i'm running a fire breather OS motor
I'd also like to point out that the AE angle tapered pistons are not identical to the Kyosho pistons. There are some subtle differences that I think make them a lot better suited for our car.
Have you tried the short link, narrow pivot setup at Rev yet? If not, you should give it a try. Compared to the longer link normal setup, the car rounds through corners a lot smoother and with less twitchy input to the steering wheel.
