First off, you can lean her a little lower....just watch your speed so that you don't low-side.
Second, you need to hang a little more off the seat. Try and make sure that your butt is slightly hovering above the seat. A good gauge of how far you should be leaning is your butt crack. Make sure that it's at the edge of the seat. You can also spread your legs more. Bring the leg that is on the turn side out further. A good judge of how far your leg should be out is this: stand with both feet together, raise one knee up to waist height, and then spread it all the way out until it's perpendicular to your body. Try ont to twist your body when you're doing this; your body should remain facing forward. If you can't do that, then focus on some flexibility exercises.
Third, keep yourself on the balls of your toes...it'll help you to switch over more quickly.
Fourth, look through the turn....keep your neck in line with your side view mirror. Shoulder should be below, head should be above the mirror (for obvious reasons)
Keep steady on the throttle....decide your cornering speed BEFORE you enter the turn! It can be pretty disastrous if you decide to brake in mid-line or if you decide to twist more throttle...
That's all that I know...you may also want to PM or ping some of the track people...Oracle and Howlin Mad come to mind. Please don't quote me on these techniques...I may be doing it wrong.
No fair flaming too badly, ok guys? I'm just a noob....for now. I hope this helps, G...
