I remember why I don’t play roulette much in vegas any more (see yesterday’s post). You never know what’s going to happen sometimes. The Sierra Sierra EVO 8 had a rear differential mount failure in the first time attack session on Sunday that prevented Bomarito from completing a timed lap. The car was running solid all day Saturday and even cranked out a 1:01.3 in a Sunday morning practice session. The constant beating of the Nashville Super Speedway’s relatively rough infield to oval transitions and the massive G loads of the oval banking took it’s toll on the SSE EVO’s rear end and bent the front portion of the rear differential mount and cracked the cast aluminum part of the diff mount in two places. That’s too bad since we still had some more boost and softer tires to use in the actual time attack sessions.
