I would guess they come standard with the air dam and you can option a skid plate similar to the one on the Pro and TH. And this event was about driving experience, not efficiency, so they optioned them for better clearance, rather than standard equipment.Interesting. I wonder if they've already decided to leave the air dams off the TRD-OR and PR trims.
Hopefully someone shows that SR some love and attention. Would be good to see what the absolute baseline is.
