There is a sticky here on adjustments for caltracs. (Maybe already mentioned)
First thing I would do: get some rims for the rear that fit (diplomat 15x7s, from the boneyard), mount and run the slicks.
I have a set of slicks to mount, but would also like to get enough traction to not feel like I'm on ice. Chip and seal roads also don't help. I'd like to get a decent setup before going to the strip, which will unfortunately probably be spring of 2025.
