New personal best at the Ridge with the HOD advanced group. First time driving with an advanced group and it felt like the right place for me. Made some changes to my driving line and came out with multiple 1:52 lap times with this being the fastest one. Tires are Kumho V730 about halfway through their life. I added an Evolution Racewerks catless downpipe, and BM3 Stage 2 tune on 91 octane since my previous hot lap and the upgrades seem to be worth another second shaved off after going from 1:53 to 1:52. I do find myself managing heat in the tires and brakes more often now though. Garmin Catalyst showing an Optimal of 1:51.56 as the delta on the video which seems like I'd have to get lucky to achieve. If I go back to the Nankang CRS I think its very attainable.
