Recommended performance accessories for the new Rivian R3X?

So I finally put my deposit down for the R3X and I'm already planning some weekend trips out near Bend once it ships. I've been digging through some early threads and I'm seeing a lot of back and forth about underbody protection. Some guys say the factory shielding is plenty for light rally stuff but others are swearing by heavy duty skid plates from third parties. I'm worried about the weight though because I have a two hour highway drive just to get to the trails and don't want to kill my range. Also saw some talk about wheel spacers for a wider stance but wouldn't that mess with the suspension tuning?

What kind of performance or utility accessories are you guys actually planning to get once yours arrives?
