Notes: 
My second day on Hankook RS4s. I am starting to get more comfortable with these tires and the fact that these are akin to driving the M2 on some amount of slip angle all the time. Despite a lot of "sliding", these are very predictable and consistent for an entire session and at a wide pressure range. As before, these tires take about half to 3/4ths a lap to warm up, but you don't need to be slouching for them to get up tp temp. 

Picked up a second since the first day which I attribute to 1/ Getting more comfortable with the behavior of the tires, 2/ Getting more use to the torque curve of the Pagid RSL1 front brake pads, 3/ Carrying 2-3mph more before braking for T1, 4/ Carrying 1-3mph more before braking for T11. (4) was the most revelatory to me as a driver - I found that I would press the throttle hard to the floor while climbing the hill after 8b and then back off a fair bit; relaxing my right foot and smoothly pressing the throttle to the floor let me slowly carry WOT for longer. I still breathe off before the top of the hill, but am starting to build new muscle memory.
