They love to go for a walk, usually when I see a store with stock I grab 2 or 3 as they always go missing.

so with this explanation why add any shins to hubs if all you need to do is remove shims from inner balls that already have 3-5mm stacked up ?

There is no right or wrong way to go about it. It is up to you and your situation. In general, if you can't remove any shims at the inner hinge point then you will have to add shims to the outer hinge point to get the same effect. Contrary if you can't add more shims to the outer hinge point because of wheel clearance then you will have to remove shims at the inner hinge point. If I am right, adding shims to the outer hinge point will raise the RC to a lesser degree then to remove the same amount of shims from the inner hinge point.

Its all about roll center. Say you had 4 inside 1 outside, and went to 3/0, the roll center is now higher even tho the angle of the link is the same

I agree with this because the link is a little closer to the bottom arm with the 3/0 shims. However, it's probably just a very slight difference so Oleg was probably simplifying it by saying you could treat 4/1 the same as a 3/0 upper link.

Yes, it will be higher on 0,02mm at precise calculations. So actually it can be described as "the same RC".
Others parameters will be changed at thus more, for example the caster flex level and it will make more sense than RC 0,02mm change.

The other more common design does not rely on the top link as it can just move back and forth at will. They rely on the bottom arm along with the C block to hold the caster in place. I'd be interested in which design works better. I'm betting the double top links work more efficiently. Less moving parts and good triangulation. However, I would think that adding shims on top of the steering block will increase the caster flex. So wouldn't you rather use zero shims on top of the steering block and just reduce the shims accordingly at the AM19 to get the desired Roll Center? Oleg, you amaze me with all the knowledge (and smarts) you possess. Just one of the many reasons I love my two A800's. Amazing cars.

Less moving parts less play. Looks like it has a steering limiter built in, possibly adjustable with different width shims on the screw underneath.

In the MonacoRC video Max mentions a different topdeck for the carbon car but this looks the same as the topdeck we saw on the alu car previously.

Alright, I've made up my mind. I want the new car. lol. I have been trying to decide between this and the new Xray since the other guys are getting the xray. But I just don't think I can go back to the blocky car after having an 800. Now I just need my Christmas bonus so I can place the order!
