This page covers an old and outdated topic. For the system that replaced this one, go to Option Parts.
In Drift City, prior to the Stage 2 update, parts could have one or two special effects, which were shown in pink under a part's statistics. These effects were purely random, and it was possible to end up with more than one (even of the same type). As of Stage 2, only a few parts still have the old part effects. Aside from the Shinoya parts released with Stage 2, any part that has a part effect is a collector's item and can sell for a high price.
Range: 2 to at least 5 points. Lower values are more common than higher values.
Note: Speed parts can also have this effect. A +13 speed part with a +2 speed increase effect is the same as a +15 speed part in terms of effectiveness.
Acceleration Increase
Text: "Increases acceleration attributes by X points."
Range: 2 to 20 points. Lower part with a +2 acceleration increase on its level.
Durability Increase
Text: "Increases durability attributes by X points."
Range: 2 to at least 5 points. Lower values are more common than higher values.
Note: Durability parts can also have this effect. A +13 durability part with a +2 durability increase effect is the same as a +15 durability part in terms of effectiveness.
Note: Of the statistic increase effects, this effect is the least valuable and does not add to the value of any level of part.
This part effect has been replaced by the Dura Plus family of option parts.
Boost Increase
Text: "Increases booster attributes by X points."
Range: 2 to at least 5 points. Lower values are more common than higher values.
Note: Boost parts can also have this effect. A +13 boost part with a +2 boost increase effect is the same as a +15 boost part in terms of effectiveness.
Party Durability Increase
Text: "Increases durability attributes of all group members by X points."
Range: 3 to 6 points.
Note: Durability parts can also have this effect. This effect can also stack with the Durability Increase effect.
Parts Drop
Text: "Increases chance of parts drop by X%."
Range: 3% to 9% Lower values are more common than higher values. Higher percentages than 6% on one of these effects are very rare and are worth much more.
Note: This only affects chances to get parts from combos and hitting HUVs.
Note: Multiple parts with this effect have their percentages added together.
Note: According to some players, this kind of part doesn't work properly.
HUV Critical Hit
Text: "Improves chances of a critical crash to HUVs by X%."
Range: 3% to 9%.
Note: This is one of the more valuable effects. A 9% HUV part can sell for several thousand Mito depending on its level.
Note: Multiple parts with this effect have their percentages added together.
Speed Loss Reduction
Text: "Reduces the amount of speed decreased after a crash by X%."
Range: 4% to 9%
Note: Multiple parts with this effect have their percentages added together.
No Speed Loss While Boosting
Text: "While using the boost, speed will not decrease even after crashing."
Note: This is a very rare and valuable part effect. As of this writing, few have been confirmed to exist (less than 10) and it is unknown how much this part effect is worth.
Added Experience
Text: "Increases obtained exp. by X%."
Range: 1% to 3%
Note: This is a very rare and valuable part effect. These parts can often go for 100,000 Mito or more in the Auction House.
Note: The increased experience is awarded after gaining enough experience where this effect would award a whole experience point. This effect does not award fractions of an experience point or use rounding to determine when to award experience.
Note: Multiple parts with this effect have their percentages added together.
Fuel Capacity
Text: "Improves maximum fuel capacity by X%."
Range: 1% to 7%.
Note: This effect does nothing for improving fuel efficiency. Not worth very much.
Note: Multiple parts with this effect have their percentages added together.
Fuel Efficiency
Text: "Increases fuel efficiency by X%."
Range: 1% to 3%
Note: Do not confuse this effect with the Fuel Capacity effect. This effect can help offset the fuel costs of patrols, races, and other long drives.
Note: Multiple parts with this effect have their percentages added together.
Booster Time
Text: "Increases booster usage time by X seconds."
Range: 0.1 seconds to 0.5 seconds in increments of 0.1 seconds. Lower times are much more common than higher times.
Note: Multiple parts with this effect have their times added together. Can be very useful in races with a long straightaway.
Max Speed Increase
Text: "Increases maximum speed by X mph."
Range: 1 to 3 mph
Note: This is comparable to the speed stat. This effect is rarely ever seen, even in the Auction House and is more important at higher levels, when the speed stat increases the top speed by much less than before.
Note: Although displayed in-game as MPH, this effect actually increases speed by the value in KPH. This explains why after equipping this part a car's max speed doesn't always increase by as much as the part effect says it will.
Special Super Stop
Text: "Special super stop (Drift + Backward Button while driving)"
Note: You must have at least one part with this effect equipped in order to use Super Stop.
Note: This effect is rare but isn't worth much. Super Stop only decelerates about 1 second faster than decelerating normally.
Special Turbo Boost
Text: "Special turbo launch (Drift + Forward Button while stopped)"
Note: You must have at least one part with this effect equipped in order to use Turbo Launch.
Note: This effect is rare and valuable. Most parts with this effect can sell for 10,000 mito or more in the Auction House.
