I just started to track my bike this summer, and riding for 2 yrs. but I have a track prepped car, and I've been tracking that for 5 yrs or so, and a graduate of skip barber racing school (3 day). I'm a low B+ but prefer to ride B- for now. never kept time, but the guy with the 848 next to me, he used to track cars as well, and he's a B+/A- rider, but was in the B- group with me, b/c a bunch of his friends were supposed to go, but no showed.
Anyway he followed me for a few laps one session and kept lap times. so that's how I know I'd be a low B+. honestly I'm just working on lines and initiating turns correctly, as well as accelerating out of the apex, and threshold braking.
I will work on my my body position at my next trackday, aka getting a butt cheek off the seat. I don't really care about dragging a knee, I know it'll happen eventually. I might have to raise my rearsets again, so I can keep the outside foot anchored.
is amsoil brake fluid that much better than motul 600 or motul 660?
