Lime Rock - The Line
Every time I make it out to Lime Rock, it takes a session or two to get comfortable, so this will be my cheat sheet to remember for next time. Start out with the 315 35/17 Kumho's at 30 psi rear and 32 psi front. Make sure data logger is turned on. Big bend - I was braking at the imaginary #7 marker last time, and running a late apex. The car is just too heavy to do the double apex line. Downshift to 4th and track out to the rumble strips, and bring it over to the right for a very late apex at the esses. Hug the left side of the track (almost no track out for the left hander), and an aggressive late apex for the right hander onto noname straight. It goes off camber at the kink. There were 3 levels of braking cones set up for the uphill corner. I was braking at 2.5, and sliding the car into the corner. If the car was straightened out early, I could get on the gas sooner, without worrying about the back end coming around as I crest the hill. Hadn't picked out a brake marker for West Bend, and could work on a more aggressive line tracking out to the rumble strips. Downhill corner, hard on the brakes early, to set the car up for accelerating through the apex and keeping the rear tires weighted. Late trail braking made the car want to rotate in the corner, which gets hairy with the cold track and hard tires. This was around 4200 rpm in 4th gear (3.70 rear, 1:1 4th, and 25.5" circumference tires). Next time I need to focus on the line for big bend. It's very easy to become distracted with the dirt around, and be too late turning into the apex. Also must stay towards the outside of the track before turning in, rather than creeping in early.
