Very short and easy achievement (once you have finished Cyberdriver). You need to do only 2 kart races and find two items (a battery and a microchip).
You must first finish the Cyberdriver mission. Also, eKart races will appear as a Side Mission, as it is not a main mission. Thanks to everyone in the comments for your help rounding out the solution.
1. YOU DO NOT NEED TO WIN THE RACES, so don't worry about speeding around the track or beating others. Simply finish.
2. After the first race, you need to find a battery. This is in a secure area, but a large space with lots of cover and not many guards, so pretty simple to either sneak or guns blasting.
3. After the second race you find the microchip. It is in the Nudle campus, where you can fast travel, and is not in a secure area. Climb up near the door and you are done.
4. You don't need to do the 3rd and final race to get the achievement.
