As I mentioned, every car gets a base class and weight. From there they pick/choose the best mods possible to MAX the car out for the class. However, you do have the option to UPclass or DOWNclass depending on what type and how many mods you do.
Up-Classing System (TTF-TTA only)
Modifications and Point Assessments:
If your car accrues 20 or more points you will be bumped up in Class. There is no limit on the number of classes you can bump up - a car with a high level of modifications might move up several Classes.
20 thru 39 points - Up ONE Class
40 thru 59 points - Up TWO Classes
60 thru 79 points - Up THREE Classes
etc
Where do the EVO models baseclass (aka start)?
See below. My car is bolded.
Mitsubishi Lancer Evo VIII ('03-'05)(AWD) TTC** 3263
Mitsubishi Lancer Evo VIII MR ('05)(AWD) TTB 3263
Mitsubishi Lancer Evo IX ('06)(AWD) TTB 3263
Mitsubishi Lancer Evo RS ('06)(AWD) TTB 3219
Mitsubishi Lancer Evo MR ('06)(AWD) TTB* 3285
Mitsubishi Lancer Evo X GSR (2008 (AWD) TTB* 3500
Mitsubishi Lancer Evo X MR (2008 (AWD) TTB** 3500
Note: One (1) asterisk * on a base class assignment denotes a 7 point initial assessment, and two
(2) asterisks ** denotes a 14 point initial assessment that is added to the total number of
modification points to determine the final competition class. This is done to provide more initial classing options for the multitude of cars out there.
