Also, RR camber is another safety issue at Cal Speedway as you'll be placing all that load on the RR tire's inside edge thru the banking. Where I usually run 3.0-3.2 in my rears, I drop the RR to 2.5 max for CS race weekends.....

Ill try and make it out later this season. I really want to race there. I have to do some testing first to make sure that my splitter can handle 155mph! ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
(I know it can handle 140mph, but that was with a 20mph tail wind at t-hill

Tom are you running 650 or 680 diameter rear slicks? The banking at CS (run CCW) requires you run enough pressure in your RR tire to handle the load transposed upon it when you're flying thru the banking. It's even more relevant with that big-*** wing you have abck there. There have been numerous blowouts on that banking from underinflated RR tires. Not much fun at 150MPH which I suspect is where you'll be running. The Pirelli Cup tires (and Michelin & Yokohama Cups) are 680 rears which carry more volume which equates to higher load capacity and safety....

Fabryce can you locate the video of James starting DFL in the PCA race there a few years back in a 6-cup? That video would really help show the proper way to run CS for drivers that haven't been there before. James's run from DFL to the front was damn exciting....

JR: Scott has the tires right. I've been warned about the banking and the potential problems by Jerry Woods folk. They will be providing transport and track side support so we will be adjusting as required as the weekend progresses. I'm also bringing 3 sets of rear tires just in case.
There are a few videos showing the proper track configuration on you tube. They give a good flavor of what to expect. Based on the times I see from the 2010 race, I hoping to get below 1:50 and hopefully close to 1:48. I don't think I'll be competitive against the POC guys in GT3R as the car isn't optimized for that race class, but I expect it to be fun.
Mike: I think Rich Walton will be running the '10 cup in those races too.

I expect you'll be in the 48's once you get comfortable. Your competition is the #23 993 RSR, Chris Cervelli's old car. He's usually in the 45's there. Have fun, stay safe....

Here are a couple of videos of laps around 44s-46s. They are by no means perfect (had not been to CS in over 3 yrs when these were filmed and there's definitely another couple of seconds in the car according to the data), but reasonable for learning the track.

John: Have fun at BW, I'll be there in a couple months for my annual trek down (PCA Race in late May) - I was happy to break 2:00 for the first time last year (#1 CW with Star Mazda).
I see that Richard Price will be at Fontana too. He usually gives me a little trouble but I can usually beat him and his 993 cup, a 993 RSR will be tough but I'll have fun trying.

Thats a great video. Thanks for posting it again. starting to memorize the lines! hard to not picture where your car will go if you have a tire blow out during the banking.
how many cars get wasted in a weekend with POC or NASA from the high speed walls?
