Joliet IL autobahn north course in a C6
May go out there in a couple weeks for the first time running the north course. Running HPDE only, this is my first time at this type of event. Any one run this track? Looks like I can go around using only 3rd and 4th. I have a 07 base, M6, all fluids have been changed to redline syn, Mobil 0/40, added a 4 pass cooler to the P/S, brakes will get Motul fluid a few days before the event . Not going to go 100% ***** out as a friend will also run the car in intermediate level after I pull in. Car has newer nitto invo's with new centec solid rotors and bobcat pads.

I'm not a member at Autobahn (not yet... thinking about it for next year), but have run there many times in HPDE's (C5Z currently, but other cars as well). I second what Adam said... don't run a street pad on any track. Also, front rotor cracking is pretty common on these cars, so you might want to have a spare with you just in case.
And I also agree with Edge04... you'll probably only use 3rd and 4th gears with 2nd gear being a possibility coming out of the slowest turn they have: turn 2 on the North configuration.
A fast line through turn 1 sets you up poorly for turn 2 and you'd want to grab 2nd gear (this is the faster way around the track... don't compromise a high speed turn to do a little better in a low speed turn). But taking turn 1 at really high speed is scary, so I usually compromise turn 1 which allows me to set up turn 2 as wide as possible, and then 3rd gear is fine.
Try it both ways as your comfort allows, and have fun.
Here's one lap on the north course where I took a conservative (safe) but still pretty fast line... sun was setting, so the lighting is pretty bad, and the GPS-based speedometer is useless, but you can get the idea. Slow turn 1, wide setup for turn 2, only went down to 3rd gear. Turn 6 is a very late apex so you can gain a lot there on the guys that don't do it right, and it's also safer because the exit of 6 is one of the few places you could find armco if you screw it up really badly.

Turn 6: never, never early apex. That turn is known as "never too late"

Having only done HPDE's, passing between 1 and 2 has never been an option for me, but it does seem like it would be a great passing zone in an actual race. They only allow HPDE passing (with a point by) on the front straight and between 6 and 7, at least in the events I've run.

Great info guys, maybe I'll buy a spare set of rotors and the front race pads. It's looking like having my friend run right after I finish my 20 min beginners session without any cool down may be asking for BIG trouble ! I do plan on having an instructor, I also have the z06 brake duct work in place and some scat hose so maybe I should at least run the hose close to the rotors, ( no spindle duct system yet) .

No, issue with running with nannies is you will kill your pads and rotors. For novice best is to take it easy and learn the track. Beginners tend to over brake and that tends to put a lot of heat in the braking system. You can run with the nannies on if you take it easy first thing is to check your ego at the door and listen, watch and learn.

Instructor said I drove the line perfect, braking and throttle inputs were perfect. After third session noticed the belt was frayed, nursed it home and on further inspection noticed balancer bolt loose and balancer moved forward about 1/2". Replaced it with a powerbond sfi rated one and a earls/arp bolt. This must have happened before as the rack had wear marks, I'm glad I pinned the HB and also went with a aftermarket bolt torqued to 240 lbs with loctite!
