Yes, TBR is still very much in operation. If you can't get through, leave a message and they will call back promptly. They sometimes can't hear the phone on the shop floor.
They should be back from the Baja 500 today.

 

Just in case anyone wanted to know, I spoke with Ryan from TBR this morning, and checked the Baja 500 standings, a Bombardier X equipped with TBR suspension components was the winner, for the second time this year in a SCORE sanctioned race, with TBR's team coming in 5th in the Quad Class.
That makes 2 Score victories and 2 Best in the Desert wins for TBR equipped quads so far this year!
