Need for Speed Heat

You must have a vehicle equipped with all road traction parts. These parts are denoted by a steering wheel symbol. A list of the parts that can be changed in this way are the suspension, the tires and the differential. You can use parts that upgrade multiple aspects of the square but it is recommended that you go for pure handling parts. . These parts must also put you on the bottom line of the performance square (again denoted by the steering wheel) for this to work. Some cars will not be able to do this at low levels and some cars will not be able to do this at all. These parts specialize your car for sprints that take place at night but can also be used in circuits. It makes it easier if these races are rated much lower than your current car just in case a driver over the recommended PER appears in the race. Once you come in first AND ONLY FIRST, the achievement should pop.

There are 4 separate achievements related to "Winning a race with handling parts for "maximum" (off-road, drift , road and race) traction equipped" The key to earning these achievements doesn't have much to do with any specific part setup but how each part affects the particular vehicles handling "graph". I've provided 2 images of examples of a MAX build that would yield an achievement(s) and a build that would NOT yield an achievement.

Pay attention to where the dot on that graph is located in order to setup your car for any of the 4 particular achievements. The ONLY parts that affect this handling graph are SUSPENSION & TIRES under the chassis category and DIFFERENTIAL under the drivetrain category. MOST exotic/sports cars in the game can achieve "max" handling in all categories with the exception of OFF-ROAD. So to put things simple just adjust the 3 parts I listed until the car reaches max in the desired category. For your off-road achievement I'd suggest grabbing a truck or SUV of some kind due to many cars being not able to achieve max off-road even with the best part rarities & yes rarity DOES matter.

Lastly, go and WIN a race with your new "max" vehicle in your desired category. I can also confirm that drift trials count as a race.
