Here's a video of my last run at Infineon on Sunday. This was Group 2, so passing was only allowed in the straights. The reason it was my last run is because one of my coolant hoses burst

You can hear it around 9 minutes into it. I had overheating problems all day, most likely head gasket related, so I wasn't able to push my car very hard. Unfortunately I had to let a Camaro get away because of it. This was my first time at this track, so I was still experimenting with the line and shifting points. I was trying out some new tires, Azenis RT-615. 215/45/16 front, 255/40/17 back. These things STUCK like no other street tire I've driven on. They were considerably heavier than my old Toyo T1-R, and I could feel it in the steering wheel and under braking, but they had awesome grip. Anyway, enjoy. Hope the link works. I'll put it on YouTube tomorrow, as well as my first run, which I haven't uploaded yet.
Oh by the way... a lot of duct tape on the hose in the engine bay, and I was able to limp to a Kragen with the radiator cap off, refilling with water every 2 or 3 miles. Then Kragen came through with a replacement hose that got me home just fine.
