Been messing around with this group for a little bit, at different tracks, and conditions. Had a race, I didn't know if I was going to be able to win at Watkins Glen, until the last lap, and even then it was iffy. Tried them out at Trial Mountain, which wound up being a pretty easy win, but made a for a few decent shots.
Real Color reds for each brand. The Nissans, I used Xanavi or Super Reds, Porsches are Indirot( something like that) the 930 is default Color(there’s actually a red one in the UCD, I’ve had mine for a while now). Mitsubishis((GTO, EVO 4,5) are Passion Red, but the Tommi Makinnen is its default Red. The Testarossa, M3, NSX, were the default Color. ZR-1 is factory Bright Red for that year. Formula red for the S2000. Both Supras are Super Red V. WRX Type R is Pure RED. Lamborghini is Rosso Siviglia.
