All I can add is you want to stay out of EDC Sport unless you want to switch in and out of it depending where on track you are. Your power and tire changes are already making a huge difference over stock, about 20-30 seconds or so by my guess. I doubt you are giving up much time because of body roll although on video we've seen inside tires lifted off the pavement. I'm wondering if you need a bit more tire up front, perhaps a square setup.
Are you running with DSC off?
