Geeze it were hot. I started out with 45+ heat-cycle v710's on the e36 and slid around for two sessions. Gave up and put on the new v710's. Picked up maybe 5 seconds with those but after 1.5 laps it was still like driving a wet fish. I don't think I got within three seconds of February's 2:06.x 
v710's are really an autox tire. I wonder if other r-comps are better in the heat...

Just got back. BW is certainly a fun track, but the weather was not!
Thanks to both Dan and Bob for showing me around the track on Saturday, and another thanks to Dan for letting me share the garage to get out of the sun, even on Sunday when he couldn't make it. Remind me to buy you a drink next time
I only managed to time a few laps today using the onboard timer in the DIC, but I managed to clock off a ~ 2:11.80 this morning. I think with some refinements I can probably get it down another second or two.
I got black flagged the session after that (on only lap 2) for going off riverside (T7) when I gave one point by, but two cars passed me which I didn't expect. It was an easy off, but they were enforcing a "four wheels off, lose the session" rule.
In the afternoon, the temperatures were getting ridiculous. 98F ambient. I started to fade my brakes (Carbotech XP10/XP8) and my street tires (Kumho SPTs) were getting extremely greasy, so much so that on the last lap of the last session I lost grip going through the bus stop and spun out.
Good fun track though. Very fast. I'll try to get some videos up later.

I personally hate the R6s though. They fall off considerably after every heat cycle, your braking points are drastically changed, they heat cycle out far faster then the tire actually wears, etc etc

"loose your session" rule on sunday for it.
Sunday was slightly better but we sill had way too many off, including a pretty bad one where a car rolled 6 or 7 times.
Both driver and passenger were OK ( very lucky) but the car was destroyed.

Maybe it was the heat affecting the drivers. Heatstroke can really mess up your reaction times and judgement. I was a little light-headed getting out of the car after the last afternoon session.
I think I'm going to avoid Buttonwillow and Thunderhill through July and August to stay out of the heat. Laguna and Sears ought to be a few degrees cooler.

I'm not sure why ( was not the track since I raced both days and it was fine) but on Saturday we had a very high number of drivers going off, spinning, etc, to the point that we decided to put in place a

That stinks about your hub failure Dan. But on the bright side it's always nice to hear about track guys helping eachother out when needed. We have all been there (or will be) and it's nice to know that other guys will step up to help like that .
I've gone through 2 hubs so far and I'm going to replace them all with skf hubs and keep my stockers for spares. You can get them from HardbarUSA if you want.

I looked at the Hardbar set and they have the longer studs installed so I will go with the Pfadt's with the standard length studs as I have no need for spacers and don't want to go to open lugs just yet.

Here's a lap I did. Timer on the DIC read 2:11.80. I think I've still got at least a couple seconds left in it considering the sloppy entry into the esses and the bit of traffic.

The exit from the esses can get a bit scary. I had them worked out last time but this time I forgot how to do them 
Driving all over that berm on the left at the exit really helps - it looks high and everyone avoids it and it tips the car on its ear, but it's surprisingly smooth.
Seems that I managed to put together a 2:06.08 on the first session with the new tires - a whopping 0.07 second pickup. I need to find a different tire to use in summer.

I still need to get my speed up for sunrise.

Thanks Dennis. I probably won't be able to make it, but I need to get back to THill at some point. I haven't been there in a year and a half. Have fun out there
