Got out Saturday at Laguna and had a great day running with Mooty and some quick SoCal TT guy. This was my first GGR event and they run a nice event, although it's not a ton of on track time. Private days spoil you for seat time.
Ran a PB 1:41:80 and think I can get into the 1:40's if I focus. The whole lifting for sound bothers me but looking at the recent posting for the HAL 9000 solution leads me to think the lifts will soon go away. I think I'm loosing .25 seconds so really I just need to put a proper lap together. Theoretical best was a low 1:39 so it's there. And Joes easily putting it all together.
The placement of the SmartyCam external mic into the car seat anchor latch behind the passenger seats works well and gives me sound that is good enough for my liking. I posted a video of me making a mistake in T2 trying to catch Mooty to illustrate the audio setup.
I had new PSC2s for the event and I had been targeting 32/33 psi hot for sessions. I'm starting to thing that they might have a touch more grip at 34/35 hot. My first session had them around 35 (but the track was cooler) and I was left with the impression of more control. I could have just been driving smoother but now I want to try out a tiny higher psi. Anyone got any thoughts on that?

I have concluded the same and my temp readings I have done, although not extensive, have showed the same. I have settled on 34/34.5 for now and it feels good. I have never felt that 32 feels better. Going a bit higher will also be a bit better for the outer edge wear on the cup 2's.

Matt that is a great time given you were lifting! Can you post some video of you going thru 5 to 6? I'm going there weds and still don't have a solution. I've only driven LS once so far in the GT4 and I'm pretty sure I'm going thru there slower then I need to (especially if you're only losing .25.)
thanks Rich

Sorry I missed running on Saturday with you guys. Would have been really fun. There was plenty of open space Sunday, but traffic on the way home was killer. See you Friday!

Excellent wide angle video and great audio, Katman! Thank for sharing.
I will look into doing the same. What mount did you use to secure to the seat's backrest?

SmartyCam is mounted to the cross brace of the GMG bar via Ram mount ball joint. Mic cable just fished into the child seat slot.

What mic did you use? Is it a generic mic with 3.5mm cable or some special SmartyCam mic?

It's the AIM Can cable with integrated external mic. Part is available from the Aim SmartyCam page under accessories. Part number on the title slide of the video. Easy to get from any Aim reseller.

Drove LS yesterday with HOD - 90db day. Blew sound twice running out of 5. Any throttle in 3rd didn't cut it. I had to stay in 4th and keep it under 5500 RPM. Hoping the GPS controller will be good for 90 db days as well.
I still managed a PB for me of 1:44 which was 4 seconds better then I had done in the Cayman R so I'm ecstatic with the car.
One difference I noticed after watching your video and Joe's was how we are driving turn 3. Joe is going back to second where it appears you are staying in 3rd which is how I was driving it as well. It does feel to me like 3rd is a little tall to get a good track out of 3 (at least at my exit speed) but getting to 3rd and then right back to second in the 2-3 straight seemed like a hassle the one time I tried it. I think I will work on doing that next visit there.
I went with staying in 3rd thru the corkscrew after watching you guys - much better!
