Dodge Challenger/Charger SRT Hellcat
Dodge Challenger SRT Hellcat:
MRA should be decreased slightly.
0-100mph: 7.3s -> 7.6s.
(Had to ask help for this one)
Dodge Charger SRT Hellcat:
Handling should be improved, as it performed better on the skidpad than the Challenger. (0.94 vs 0.92)
Here's the screenshots I took for easy viewing.
As you can see, the Widebody performed the best, then followed by Charger, then Challenger on skidpad.
Note: the Widebody is slower in that test is because it's the manual spec, while the two others are tested in automatic.
