Hi, I can help a little. The reiza class, i.e, in your case, 'reiza1', determines which RFM to load the cars into. So, most go to reiza3 or 4, being mini (3rd in scroll menu) or camaro (4th in scroll menu) sections. BUT. Easily change this by adding your own rfm and a tga (loading screen) so your cars, e.g, DTM 2013 have their own section in the game like V8 stocks do compared to F1 classics for example. You can use text crawler to edit your veh files in one or two clicks.
Essentially, you could also leave the rfm for reiza1, and add another line for sub-category, but in a championship, it might still select other classes, whereas single race will not (possibally, i've had differing results depending on mod). Talent files can be a name of driver or team name or car number itself, hence the description (but you might want to get that fact-checked).
Actually, I have already tweaked this very issue myself for quite a few mods, and can dropbox the relevent files. I have the ETCC79, Touring masters, DTM 2013, GT1 GT500, Sports Prototypes Historic GT and more all with their own rfms/tga thanks to the following link.

Examples for DTM changes I made, and rFM
1)
Number=05
Team="Sport Team Rosberg"
PitGroup="Group03"
Driver="Eduardo Mortara"
Description="#05 Eduardo Mortara"
Engine="Audi"
Manufacturer="AUDI"
Classes="reiza56, DTM_2013" [< I added reiza56 as a new rfm] I could tell DTM to also show up in another car class buy adding the relevent reiza rfm number here, i.e, reiza4 (camaro, seeing as camaro is the 4th car class in the in-game menu).
FullTeamName="Sport Team Rosberg"
TeamFounded=
TeamHeadquarters=
TeamStarts=
TeamPoles=
TeamWins=
TeamWorldChampionships=
Category="DTM 2013, Audi RS5 DTM" [< here I can add sub-category]

2) From the rfm; (''<<'' only the sections needed to change, your scene order/points etc is your own choice)
// Game/Season Info:
Mod Name = DTM 2013 <<
Track Filter = StockV8
Vehicle Filter = OR: Reiza56 <<
SafetyCar = Mini_SC.veh
// Seasons: DTM 2013 <<
Season = DTM 2013 <<
{
FullSeasonName = DTM 2013 <<
BaseCreditMult = 0.0
MinExperience = 0
EntryFee = 0
Vehicle Filter = |Reiza56 <<
Max Opponents = 23

{
}
Also, for authenticity, add you own tracks from DTM 2013 calender or whatever by copy/paste the track name found in the .gdb [gamedata/locations/</circuit choice>/<layout>/.gdb. Copy first line at very top of gdb and put into scene ordr in your rfm. (use notepad + +.)
I hope some of this helped. ? I am just a fan and learning from all the pro's around here
