Also can I lower the r.c. by adding shims under the front arms?
Can I also add reactive castor by adding offset shims to the upper arm?
IT pretty much works like a touring car. And yes, tilting the upper arm adds reactive caster.

I put Jan'so snowbird setup on my car,but having a problem getting the correct ride height on it. His setup sheet says he has 4mm shims under the arms and he is using the Pit tires and his front ride height is 3.8, but with 4mm shims under the arms on my car and with either the Pitts tires or the CRC tires I still only get 2mm ride height. Everything else is the same. Am I missing something or is his setup sheet wrong?

your front springs have probably collapsed. I had 4mm on front with mine at the 'birds with the same shim pack... its all about the springs too.

Also you may check the status of your lower balls . If they are worn, the front will drop significantly. With the plastic balls the wear could be fast especially if you run ourside.

I recently noted on Facebook, somebody had set up an oil filled gear diff for the X1. Anyone have any further thoughts or info on this?

I don't think it was sealed, so not oil filled

looks like the spur gear is integral to the diff housing, which will likely limit the selection of gears..

Looks very similar to the old HPI F10 gear diff. I personally didnt liked it as it is sensitive to rear side impacts as the inwards axial force was taken purely by the planet gears.... And you would be limited to only Fenix specific spurs...

On carpet? No. On Asphalt? Yes. I ran the v2's. Pretty good. About .1-.2 slower then Pit Shimizu 71/72 combo I like. I would compare them to Rides v1. Don't get squirmy like Pits can get when overheated. Just my observation for outdoors.

I have tried the sweep tires indoors as well have some of my Co racers. They worked "ok" but honestly not as grippy and consistent as the pit/tcs/crc.

Hope that helps.
