Went under 1:30 for the FIRST TIME EVER at H2R!!

Watch closely, you will notice a continuous streak of PBs starting Lap 8 at 12:34 all the way to Lap 12. In total, I was able to shave off 1.6 seconds in 5 laps, and each lap is a new PB! Almost cried when I saw I got a 1:29 on the last lap..

Cup 2 holding up well in 55F ambient temps! I take back what I said in the last video about Cup 2 not pairing up well with XIDAs. In the clockwise track, this setup works wonders soaking up ALL the bumps on the track.

Braking is the only obvious area that needs improvement now. Today my brakes feel okay due to the cool weather, but when temps were higher, I noticed a significant fade. Used an IR gun to measure the rotor temps after 1-2 cooldown laps, and front & rear both read ~300°C. Stay tuned for brake pad & rotor upgrades!
