short of full slicks, you need to lift for T8 if you are any where close to 100mph.
at around 100mph, there is NO run off at T8. you need every bit of concrete inc the widened berm to the right.
i am not sure who told you T8 is faster than you tihnk you can do. it's T9 that's a lot faster than what you think you can do. however, should you go off T9, it's ugly.

Context. Turn 8 is faster than you think when you are in the beginner/low intermediate group, don't really know what your car can do and go into it at 80 mph. I wouldn't know about 100 mph because I'm still not confident/good enough to approach 8 at that speed. Alas, I'll certainly take your more experienced word for for it (seriously, every bit of info helps). That part of the track just bothers me as I still have images of the Vette a few cars in front of me tumbling because he was too far to the right on 9.

For what it's worth: I have a Tubi exhaust (only the cans not the central muffler bypass). I was driving Laguna Seca in April on a 92 dB day and was black-flagged with 94.8 dB Short shifting at the sound station helped (no more black falgs for the rest of the day), but I doubt that this strategy will work on a 90 dB day ...

I watched your video a few times. One thing to remember as you build speed, you really need to hit those apexes, especially high speed corners like T8. Every foot you miss the apex throws you 2-3 feet wide at the exit. At speed, I essentially drive right over the front of the T8 apex berm. Sets you up nice for the exit. And Mooty's right - at speed you need to lift, and maybe even a light brake tap to shift weight forward and get the nose down for turn in, then back on the gas to plant the car through the corner.

Great video, on that turn 8, I honestly think if you kept your foot down you would have made that corner (not that I've ever been to that track).
What's your car, tires, pads? Is it the one in the picture with GT3 Aero?

After watching both of your videos I see a fair amount of correction taking place at turn in, meaning you are turning in then realize your to early or you turn in and realize your to late both of these force you to un-settle the car in the corner, as stated before you have to get to the apex of each turn at speed or you run out of track. We all make these mistakes at the track I make more than my share for sure what i don't see in your video is you being comfortable with the car at a slip angle. I recommend A. learning the line until it is an unconscious act, B. take a turn like turn 2 and learn to throttle steer your car and find out how to create the rotation you want earlier in the turn. In a 911 it is critical to get the car turned in then get back on the gas to get the rear to stick this does not mean you have to be flat out learn to feed the throttle and how to use maintenance throttle.
Laguna will be fun and this is not Nascar so weather is not a worry and for sound yes most cars fail there I have to install a secondary external system and still have to lift (how much and when is part of the challenge)

Glad you had a good weekend up there. Pretty nasty departure coming out of T8. How's the car doing? Get the radiator fixed?

I think I caught up in getting a faster lap time, that is the curse of having a lap timer in the car! lol, My next time out at T-Hill will be focusing on the lines and hitting the apex.
As far as Laguna, my car should be right on the limit, but I think short shifting T5 will do the trick. Do they typically change sound limit every year?

My car is a 3.6 Carrera, with a factory Areo wing and front splitter. Tires were MPSS, and pads were EBC Red Stuff.

Thanks Tim! The car is all fixed now, I had to replace a broken radiator, AC condenser, plastic trim, and repair two bend wheels. I ended up buying a set of track wheels so the car is all good to go for Laguna

Have fun at Sears Pt. I'll be there at the end of the month. We're working to get PCA GGR back there next year. Fingers crossed!

Slip angle is a term used to describe a degree of slip(slide) the tire is doing while at the limit of adhesion it is not "drifting". As far as driving with the traction control on it would still allow for a little slip. I agree that your first priority is to get the line down and let the speed come once the line is a subconscious process then you can learn to feel what the car is telling you. Get Ross Bentley's book ultimate speed secrets read it twice. That will give you a lot of amazing things to grasp so when you come to the track next you can approach the learning In Stages. Since you bought track wheels I recommend staying on a street tire for a little longer you will learn car control better at slower speeds
