Just got done building my buggy, and the front has a ton of camber. Like 4 degrees. I used the 1mm spacers top and bottom like the manual shows. Is that the normal amount for this car?

I think mine ended up about 3ish. That's normal but more than I'm used to.

Before I tear a shock boot, can anyone tell me if you can pull it over the shock bottom without tearing it or are they supposed to be installed before the shock bottom. Instructions appear to have them going on after?

I don't have my buggy in front of me to measure the hinge pin, sorry.
The under drive in the rear gives more rear traction under acceleration with the same dif oil weight. I.e. Running 7k rear dif, no under drive feels similar to running 3k rear with under drive. The benfit is lower oil weight allows it to go around a corner with less scrub (one wheel sliding due to different speeds), but it will still pull out of corners by the front end.

It is possible, but VERY tricky. I put a drop of oil on mine to get it done. Next time I will pull the end off.

Has anyone tried different piston/oil combos? Started with stock setup but shocks have way too much pack. Went all the way down to 32.5 losi oil before they started feeling right.

I use mugen 600cst front and mugen 550cst in rear. I just ordered the 5x1.3 16mm pistons to try.

The kit needs nothing. You only need to buy tuning opinions if you want the kit to drive different from stock.
