Porsche GT4 RS chasing optimal lap time at COTA : The Frustration!

- Hey everyone welcome back to It's Track Time!
In this video we talk about the complexity of chasing an optimal lap time in a GT4 RS. There's a fine line between hitting the optimal time and missing it by several seconds. A slight correction or minimally missed apex, can be the difference. While it's frustrating, in the end more seat time is the only solution I know to improve consistency.
What have you done to improve your consistency on track?
Thanks for watching :)

Great video!! One thing I found out on track driving was that lap time is brutal and has no mercy.
Very true!
Really enjoying the HPDE/track day experiences… documenting of the process is so good it almost makes the car irrelevant. Keep it up.
Thanks for the feedback.
Great to hear you're finding the content useful.
Love watching. Excellent commentary
Thanks!
Plays right into the Randy Pobst video given it shows even professionals struggle with the same issues and frustration.
However his actual and optimal are much closer than mine!
Love the videos! I am curious why you went with the GT4RS road car as a track car and not a GT4RS ClubSport? Do you drive the car on the street a lot as well?
Thanks!
You couldn't buy a GT4 RS Clubsport even if you raced.
Those were nearly impossible to buy new and I didn't want the problems associated with a used race car.
Last time I went for a weekend at the track, GotlandRing, I left my Catalyst at home. Never had so much fun at a track in the 4RS. Never driven as good or fast either. There’s no prizes at the finish. Leave your lap timing gear at home, and enjoy your car!👌🏻
Probably good advice...
Enjoy the videos. It appears when you are going through the turns after turn 2 it sounds like there is very little throttle being applied. Would be interesting if you can lay your data over Randy's when he was driving your car. You speak of lateral grip but it appears you are not using it. One of the techniques I teach when instructing is to curl your toes in your boots. It should give you 1 to 300 more rpm but not so much where you lose the car. Realize I am just sitting here watching video but the car just seams to comfortable which I think is causing you lost time in your quest. You will know you are using it all when your ass starts making diamonds out of your shit...
Thanks for watching!
Randy, like a lot of pros, shoots through turn 3 and then applies heavy brakes at 4. I brush the brakes at 3 and then apply a more even throttle through the esses. In the end Randy is much faster through 3 and 4 but about the same as me though 5, 6, and 7. His advantage comes at 3, 4, 8 and all of the high risk turns, 2, 18, and 19. Interesting comment on the toe curling to get a small amount of additional throttle. I'll try that next time out!
@@ItsTrackTime Keep hunting for it. Great track and monster car!
0:40 it looks like you're realistically 0.1 up, and then you bit the brakes and the delta goes way down in the braking zone, and comes back up as you enter the corner, and then settles do being about +.15. I think the is a case of software being overly optimistic, and you "only" lost about 0.25. That's still costly for one small mistake, but not nearly as bad as "almost a second".
Similar with 3:05. You were up 1.0 before braking, and about 0.65 after exit. I don't think that 1.5 up ever actually existed, and you only lost about .35, not a full .85.
But the point you're trying to make still stands. It's really hard to string everything together on one lap.
I'm surprised you didn't mention that it's not always an issue of driver consistency. Sometimes doing your optimal in one sector takes more out of the tires, meaning it's actually impossible to get your optimal out of a later sector. Ambient temps, track temps, wind speed and direction, and so many other things besides driving can keep you off your best, too.
That is very true. I've always wondered if it's even possible to screw together all of your best sectors given, as you said, it may be impossible. What you did to achieve the best time at one sector may have hurt your ability to realize your best time at the next sector. This all says that you need to continually drive down your optimal time given you may only be able to realistically achieve a fraction of it.
Great points. Just one bad/missed corner can mess up an otherwise solid lap. Monitoring each section with the garmin is helpful but overthinking each component and then psyching yourself can also lead to pushing beyond the limits of car/driver and messing it up. I have found my best track laps (or autocross times) come when I’m being moderately aggressive and telling myself this is the time of day to get a good time down but also trying not to think about it as well while I’m in the process of doing it. It’s surprising how freeing the mind like that gets you closer to ideal/optimal. Keep up the good videos!
Thank you.
I use to not look at the lap timer as I drove and then just reviewed the results afterwards.
Now I have it mounted up higher so I can more easily see it and its messing with my head.
I need to just turn laps and forget about it again.
Great narration. I feel your frustration. I spent a few years chasing a sub-minute lap at Lime Rock in my 981 GT4 on street tires. With my work schedule I could only get to the track 6 or so times a season. Saw consistent laps of 1:01, then 1:00.4, always so close but not quite there. It took the right conditions and an extra level of commitment and trust at the right points (while still trying to keep the car and me safe) and then it happened-a 59.39. As you know, though, that one amazing lap can’t be in isolation, and requires a great lap preceding it to set it up so you fly across start-finish with good speed to start your target lap (especially at a short track like LRP). In my case, the preceding lap was a 1:00 flat. Keep the videos coming. You’ve got great insight and wisdom to share-enjoyable to watch.
Thanks you very much!
It's unbelievable difficult to crack off optimal laps in succession or even one for that matter.
I guess that's what separates the pros from weekend warriors like me.
@@ItsTrackTime ...and me. In my quest to break a minute at LRP I enlisted the help of a pro driver for a day of coaching. This was a few years ago. Having never driven a 981 GT4 before, he hopped in my car with me riding shotgun, and he proceeded to reel off 58 second laps right after the outlap. It's just another level.
Yep it's very impressive to watch these guys at work and to analyze the data from their laps.
I've been watching your videos and I'm loving your bumper cam. Do you have it in a tow hook bolt mount? Or is it suctioned to the bumper? I'd like to do the two hook mount, but most track day groups want you to have your tow hook out.
The rear camera produces the best footage!
I use a mount that attaches to the tow hook.
Search for Rennline ACTION CAMERA TOW HOOK MOUNT.
@@ItsTrackTime and Edge Addicts or Chin doesn't get mad at you for not running a front two strap?
Nice video. Really like the stuff you are putting out.
Thank you very much. I appreciate feedback like that!
Agreed, this is excellent and the camera locations and quality is also excellent
Thanks, good to hear the added video quality is appreciated.
Great video
Thanks!
Really enjoying the content definitely want to get into tracking soon im just currently getting everything in order to get my first car. Im definitely going with a brz for my first car.
Just get front pads and RB600 or better brake fluid, ensure you have a safe car nothing else is needed to go on track.
Glad to hear you find the content useful.
BRZ is a great choice.
Learn the right way with a momentum car.
How do you think about track insurance? Do you buy the annual?
Up until the 4RS I just self insured and went by the motto "If you can't afford to lose it, don't bring it to the track". However with the 4RS I crossed the threshold and started purchasing an annual OpenTrack policy.
Man your videos are the best thing I've found on YT recently. Thak you for making these. Where do you mount the catalyst camera?
Thank you very much!
The catalyst camera is behind and to the right of my rearview mirror. Out of the way but still has a good view of the track.
@@ItsTrackTime Is that the camera from the top frame in your videos? Love the narration. I have a 992 GT3 but am a novice and its really cool to hear your perspective from the advanced group.
No the Garmin camera is much lower quality than something like a GoPro 12 so I just mount one of those on my front tow hook for the top frame.
Love it, great work
Thank you!
Awesome video and narration 🙏👊🏼
Much appreciated!
Epic stuff! Keep it up man
Feed back like this keeps me filming, thanks!
Are you missing apexes on purpose? FYI all cars are momentum cars.
No my intention is not to miss the apex. ;-)
All cars are momentum cars if driven properly.
