I could be wrong but vented disks doesnt mean drilled it means theres cooling ribs between the brake surfaces. The disks are thicker and are not sollid metal from face to face where the pads interact.And that would make vented the more realistic choice.
Great video. I just got into this game a few days ago. How does that bodywork look so smooth? Mine looks like its been in a crash before I've even started to modify any bodywork, let alone drive it. I'm using one of the later body's like a '11 2.8 sedan iirc.
