Most of the time I’m doing between 74-77 through 4. I think I can still get more out of it. I just need to sack up and do it!

Being behind you in that last session was interesting seeing your lines into 6 and 11. I may try them and see if there’s anything there! Always fun to see you out at the track!
I've been playing with my lines through 6 and 11 all year. I'd like to leave it in third through both of them, but am still in the torque dip just a little bit by track out, so I've been experimenting with second gear through both. If I can drive a defensive race line through six and get the heel/toe just right I think that's fastest. But I never bothered learning to heel/toe, so I'm inconsistent with it, and it is much harder on the car. I'd rather just buy a little more grip and not deal with it.
By the exit of turn 11 I'm at the rev limiter in second. I think that's fastest, but again, harder on the car due to my poor heel/toe technique. Maybe it's time for some auto-blip programming!
Or, I suppose, I could just become a better driver.

Nice! Is your car otherwise stock? I ran high 2:08's the only time I had my BRZ out there. But, I have suspension + bolt-ons and a tune (video on previous page).

I need to not be conservative and shift into 5th on the back straight. Probably losing a lot of time there.

Hey Justin, the car is making stock power right now. Shifting into 5th will help lap times a lot. I only drop to 4th for turn 4 and focus on carrying as much speed through the corner as possible.

Jeeez, I'm doing something wrong. Nice work, Justin.
I'm very surprised you don't shift to fifth gear. Gotta do that.

I shift to fifth gear, then leave it there through T4. We're at our maximum lateral grip through there, so it's not like we need any extra power. Besides, if you carry enough speed through 4 you barely have enough time to get right and set up for 5. I shift from fifth to third just before turning into 5. It saves a shift and allows me to concentrate on my braking and line going through the highest-speed turn on the track.
Well, that's what I tell myself. Maybe I'm just lazy.

Yea, I think I was just keeping it safe and speeds down since it was the first time out there with the BRZ. After watching Robbie, and hearing your techniques, I definitely need to do what you guys are doing. I was slowing way up for T4.

Track: Kyalami GP Circuit, South Africa http://www.kyalamigrandprixcircuit.com/
Car: 2013 Toyota 86 standard spec
Mods: Vortech SC (low boost), crash bolts front, Powerbrake slotted disks, Endless pads front, Bendix pads rear, 17x7.5 A-Line wheels, 225/45R17 Bridgestone RE11S semi-slicks
Notes/Comments: My first visit to Kyalami, so I was still very cautious with the 2 fast corners, the many walls, and the quite low-grip (but excellent) surface. Awesome track!! Speedo is kph. This was my 86's 43rd day on track including several time attack events. Engine's never been opened, and minimal other problems. Love it to bits!!

Track: Motorsports Ranch Cresson, TX 1.7CCW
Car: 2014 BRZ
Mods: Ohlins R&T coilovers, AP Racing Sprint Kit (RC6 pads), JDL UEL headers (catless), swaybars (STX autox build)

I was running brand new 255/40-17 RE71r's and managed a new personal best of 1:24.7 during the SCCA Club Trials. Temps were in the low 50's and there was plenty of rubber from the Winter Festival Club Races, so conditions were great. My Garmin Virb had the GPS signal wander a bit during the lap, so my overlay is a bit off but since it was a club trial I had a transponder for times (luckily). I'm going to have to invest in an Aim unit in the future.

Fastest lap starts at 3:53.

Here is my video from NJMP Lightning. Car is modified to the SCCA autocross SSC class. For those unfamiliar with it, it has koni sport shocks, eibach pro kit bars and springs and falken rt615 tires. Other than OE brake pads, it performed pretty well and I was able to stay in the 1:18 lap time range.

It's been a while but thought I'd post this . Fastest naturally aspirated 86 / BRZ lap time around Buttonwillow Raceway Park in California, 1:59.5.

[ame="https://www.youtube.com/watch?v=GY0pV4BUbEE"]Toyota 86 - 1:59.5 @ Buttonwillow Raceway Park - YouTube[/ame]

I'm sure I can go faster next time, but I'm taking a break from the track for a while

I sourced most parts for the build from CSG:

Suspension
- Tein SRC coil-overs
- SPL rear lower control arms

Brakes

- AP Racing Sprint big brake kit
- Project Mu 999 brake pads front, Project Mu Club Racer brake pads rear

Aero

- Trackspec hood vents
- SARD LSR

Other

- Ptuning EL header (I got it before ACE header came out), ACE front pipe
- TWS 18" T66F wheels wrapped in 255 Bridgestone RE71R
- Jackson Racing oil cooler
- Cusco LSD
