I was board so I calculated the surface area of the holes people are commonly using with the xb4 and similar 1/10th buggies. I also compiled the Kyosho springs and x ray springs into one place.(info taken from petit) I'm running red front gold rear until I get the full set of x ray springs.

4x1.3=5.3
6x1.1=5.69

Track surface and temps dictate what compound. Its easier to change tires to get more traction than it is to change setup to get more traction.
Locally we have an all clay 1/8 scale offroad track. 99% of the time we run SS compounds. Tire wear is minimal. You can easily go all year on a single set of tires in a 2wd as long as you aren't constantly spinning your tires.

Tires tires tires. Thats what the local fast guy is always telling me. He's a real tire whore. lol But he's a whiz with tires. There is no real way to say you drive x condition so use y tire with z inserts.
I do know and understand tuning an onroad car a little better than I do for offroad. For onroad ideally I'd run the same compound front and rear. Locally we run sweep 32's and 28's. 32's being a little harder than 28's. If I my car is oversteering and I don't have time to chase setup I may try 32's on the front to get rid of some steering. Or I may just do that to confirm I just need to eliminate steering before I change my setup haha But it's more of a bandaid to a proper setup in my opinion.
Normally though, I just go find the fastest guy I can and ask them what they are running.

It's a combination of things. Like I said track surface and temps play a big role in the compound choice. Take for instance our local track. Its a hard packed clay. So we run SS (JC green) compounds because they will grip the hard surface better. But if its really hot out we may go to a soft (JC blue) compound, because in the heat the SS becomes too soft. For a looser dirt track you would want a harder compound because you don't want the tire to give. You want the tire to dig and grab the loose dirt. Then you also have to consider tread pattern. This affects traction as much as compound. If our track has been swept a bar code style tire offers way more grip than a double dee style tire, both tires being the same compound. The harder packed the track the shorter the tread depth needed. Looser tracks require deeper tread depth. Then you have foams - softer (open cell) foams for lower traction and rough tracks, firmer (closed cell) for higher traction and smoother tracks. Offroad tires are pretty complicated.

Did you try the progressives with the stock pistons/oils(+25 on stock wts)? I loved them on our indoor track. I stopped tweaking the car too much its too good with the right tires but our winter series is over now so will see how she does outdoors in looser conditions.

The aluminum shock caps have their own gaskets included......and they don't leak
The design on the aluminum shock caps are different so the new o rings will only fit the original plastic caps
