So first of all I've compiled this purely on experience from playing the game. So there might be more ways to get parts than I know of. I started of that I wanted to create the enemies of the game with parts and therefore took notes of what parts they were using.

Enemies can drop the parts they are using, so don't expect any Voltra Legs if the enemy is of the right type, but not wearing Voltra Legs. Enemies can drop any of the 8 parts they are wearing or just drop bits. I can't give you any chances here or such, I simply don't have enough data.

I started of giving my own names to the enemies but realized that it is confusing so instead I decided to name them based on their Colour Scheme and overall theme. "Electro Circus Megafist" for example uses the Electro Circus colour and usually comes with a Megafist Arm, Mega Core, Mega shoulders and so on.

The items will be listed in categories based on where they are equipped and in the order the Part stash orders them.

Just a collection of the items I've managed to get from the shop so far postgame.

There are Golden Chests scattered around the different levels of the game. Unlike the Blue Chests they drop parts instead of Bits. I've opened quite a lot of them throughout different levels and it seems like they share the same droptable?

Anway, I will list all the items I've managed to find inside Golden Chests here.

If you come first in the tournament you recieve a megac part for your effort. After 10 rewards you start recieving random parts, sometimes the same over and over again.

I am unsure if the order is predetermined or not, but here is a list of the items according to the order I recieved them:
Aero Stabilizer
Big Core
Bugga Head
Ice Break Head
Aero Pipes
Frostbyte Shoulders
Frostbyte Core
Kheriprogram Hips
LCD Head
Drill Legs

After that I started recieving random parts like:
RAM Head
Unknown Head
Khepriogram Core
Zylin Arm
