Shaved off 0.7s from yesterday's PB! My current PB sits at 1:49.02 on Lap 4 followed by a red flag. Lap 3 was a 1:49.08 which was extremely close so I kept it in this video for comparison. 

To drive MSR Houston fast, I think you either have to be brave and take risks, or have a lot of seat time driving it. Almost lost it in a couple corners!..
