Also, looks like there's room for improvement for Richard through sector 2 and 7. He's corner entry speed is the same as Reef's. Could it have something to do with the grey goose brake bias setting?

Don't foget that my car is SC, which should even out any advantage that Richard has from lighter weight. It also looks like I have more raw acceleration from the steeper curves and considering that I'm starting from a slower speed in most corners and end up at the same or slightly faster speed before braking. Richard simply doesn't brake as much as I do and that's just due to experience and more confidence. I'm sure that I could shave a lot more time off in the corners with less braking and there was plenty of room for track out in corners 3, 5, 6, 9, and 10. I could also improve my throttle control coming down the hill into turn 2 and through 8a to shave a few more tenths.

Here are a couple more comparisons of lateral and longitudinal g forces. It doesn't look like much on the lateral g force graph, but Richard is consistently carrying 0.3 Gs more than I am in the corners. The longitudinal plot clearly shows me over braking, but also seems to highlight how smooth Richard is on the throttle. At the top, his curves are relatively straight with a slight downward angle. Mine are a little choppy, with a slight upward slope, I suspect due to more hp.

I don't understand these G's graphs. SHouldn't the lateral G graph be flat much of the time (on the straights)? And does positive and negative relate to left and right?

g-g diagrams would also be enlightening, esp. to show how you two are trailbraking. I'll post some DL90 stuff tonight.

There are brief periods where there are close to O lateral Gs in most of the shorter straights. There are longer periods in the middle at approx. 1.7 km (back straight) and 3.4 km (front straight). Plus is a left turn and minus is a right turn.

Thought I would remind people of some blazing times at Laguna 3 years ago when the competition was fierce among S2000's. JZR did a 1:43.6 with only 17" slicks plus wing on an otherwise stock S2000, stock suspension! . Aaron B. and Rylan did 1:45's in what would be a Prod car today! .

I was doing 1:53-1:54's in a Prod car .

Made it home . Aaron had us go tp Paso Robles to eat at this BBQ restaurant, but when we got there it was a 40 min wait, so we ate at a diner next door... very disappointing and bad food. Was going to stop overnight in Buttonwillow but decided to keep going.

I had a bad engine also, and didn't get to drive when the track warmed up, so that's my excuse . And it was the water in the brake zone of 2 that made me flat spot and go off (no ABS).
Richard, it was great meeting you...I really appreciate the help you gave me, and I look forward to talking with you again...

I balance the throttle, but I'm chicken.
You weren't chicken when you were chasing after that GT3...
