Drift City/Mittron Enhancer

How do I get a Mittron Enhancer?
A Mittron Enhancer is available the same way as any other part, meaning it can be acquired from combos, successful HUV chases, the Undercity, and Patrols. When you get a Mittron Enhancer, on your screen, it will say Obtained 1 Mittron Enhancer, and the narrator will say "Yeah! Jackpot baby!".

What does a Mittron Enhancer do?
A Mittron Enhancer can be used to modify an existing part into a more powerful version of itself. When you have obtained your Mittron Enhancer, go to the Parts Shop in the Driver Dome. Click on the tab that says "Modify." Select the part you would like to enhance. Put the part you would like to enhance on the left square, and the Mittron Enhancer on the right square. Click the Modify button. This will automatically deduct the modification fee shown at the top. Assuming you succeed, your part will be upgraded by 1 to 3 points and the name will change from X to X+y, X being the name of the part and y being the number of times it was enhanced (e.g. Shinoya Beta Booster+12). Although there is no hard-coded limit of the number of times this can be done to a part, the success rate is reduced after each prior successful modification.

Modification can fail however. The failure rate increases as a part is successfully modified, so after about 4 successful modifications, you will fail more often than succeed. That doesn't mean the item will be destroyed and unequippable, it just means that the process did not work and the item did not undergo any changes.

As of the Stage 2 update, parts can sometimes break if an enhancement fails. If a part breaks, it becomes unusable, but it can be sold on the Auction House or to the Parts Shop. Broken parts are uncommon below 7 enhances and become very common after 10 successful enhances. Broken parts can be fixed by using the appropriate level Repair Kit from the Parts Shop. Using a Repair Kit will remove all enhancements from the part however. Restoration Kits are available through the Drift Shop that can be used to repair parts and keep all previous enhancements up to +12.

You can also use a Mittron Enhancer to make hyper parts. When you "modify" a Crude Part, it becomes a hyper part. Hyper parts range from level 60 to level 80 and have special characteristics that differentiate them from other parts.

When's the best time to sell a Mittron Enhancer?
Although it's not possible to hold a Mittron Enhancer for more than 24 hours without it expiring, the best time to sell a Mittron Enhancer or a Liquid Mittron is right before channel battles start each week. Everyone's frantically trying to buy up Mittron Enhancers to get a last-minute advantage in stats, and the price of an unexpired Mittron Enhancer can rise by about 10,000 Mito or more. You can easily make 200,000 off of this each week if you keep putting lots of Liquid Mittron up for auction for 3500 Mito or more each 1ml.

Hyper Parts
Hyper parts are created by modifying a crude part using a Mittron Enhancer. Crude parts are made automatically from a stack of 10 part components of a single type, which can be obtained in the game from HUVs and combos starting at about level 25. It's actually very common to end up with a lot of crude parts once you've been in Cras for a while. Unless you're near level 60, it's often a better idea to sell crude parts to the Parts Shop than to make a hyper part from them. This is because crude parts and hyper parts can't be traded or auctioned yet and you have limited inventory space.

There are a few ways to get hyper parts:
 * Doing Instant patrol missions from Officer Heather when you are over level 55. Using this method, you can only receive level 60 or level 65 hyper parts.
 * Earning a high rank in one of the high-level Lap Time rooms. Using this method, you can receive up to 3 parts of a specific level, up to level 65 for the V9 Lap Time room.
 * Earning a random item drop from a combo or HUV chase. Out of all of the methods, this is the least likely to result in a hyper part, but it is capable of awarding hyper parts above level 65.
 * Hitting the boss HUV during Rush Time. Although it is not guaranteed, you can receive hyper parts of any level from level 60 through level 80.  The boss HUV generally gives better part drops than HUV farming or combos.  Your car's V-class affects the level of parts that drop from combos and HUV farming, so it also affects your chances of receiving high-level hyper parts from a boss HUV.
 * Modifying a crude part with a Mittron Enhancer. There are 4 types of crude parts.  All crude parts have a 240 hour time usage period.  The hyper part's level can range from level 60 to level 70.  Lower level hyper parts are more commonly made with this method than higher level hyper parts.  The part's special effects and level are random, so it's possible to be level 30, enhance a crude part, and make it into a perfect-base level 70 part.

When you equip a hyper part, the part changes from a red part with flames to a black part. This means the item is now scorched to your car and can no longer be removed by normal means. The only way to remove it is by using a heat treatment kit on the part. The Parts Shop sells these for 5000 Mito, but if you're level 45 or higher, you can get them from combos or HUV chases. You can also recieve heat treatment kits by purchasing them for 500-1500 Mito each in the auction house. If you remove the part, you can put it back on or put another hyper part on without another heat treatment kit. However, swapping a full set of hyper parts with another set will require 8 heat treatment kits. This can become quite expensive through the Parts Shop, so if you have the room for it, save the kits you get from combos and HUVs.
