- Thanks to BR Racing for assisting in car setup.
My fastest lap of the day from an afternoon session, followed by a little surprise T2 drift.
This was my first time running at Laguna Seca post-repave. It rained the day before and overnight, leading to gradually drying conditions in the morning. The course never felt fully clean, though, so I was hesitant to fully commit to use of the exit curbs in a few places. In many of those same places (T2, T3, T5, T11), traction control was a major limiting factor, and on this lap in particular, I misjudged the entry to the corkscrew and lost several tenths from there to the exit of T9. In retrospect I wish I had taken steps into the uncomfortable earlier in the day.
Based on the feel of the car last weekend at autocross and this weekend at Laguna Seca, I may try softening the rear a bit to assist with on-throttle stability. Clearly I've also got to stick to running on track with TC disabled, though this didn't feel like the right day to jump right in. I should also note that I don't know how much of this was condition specific.
As ever, I'm looking forward to giving this another go soon.
Thanks also to SP Motorsports for hosting this run group.
Only modification: Yokohama Advan A052 in OEM sizes.

Thanks for sharing that’s ripping fast for a street car!
Wow, great lap, made that look so easy. I’m back at 1:39 with my GT4 and trying to get down to 1:37. You’re flying.
Slow hands on turn in, working with what the car has to give; quick hands when balancing at the limit of group. When done right, I'm not fighting the car and it should look relatively easy.
@@teddyframheinagree, and I know from my own laps, the videos don’t represent all that’s going on when you can’t feel the cars wiggles and G forces.
I think I have similar apex speeds (except T6, I’m just slow at T6) but I’m braking too soon and getting back to throttle too late.
Love that drift at the end ;). Wicked fun my friend.
Insane lap! Dream car on the dream track. 🙌
Absolutely insane. If I could consistently pound these laps out on iRacing in GT4s I'd be extremely pleased with myself, let alone doing it in real life.
Great driving as always!
Mamma frikin mia!!! Whatta lap, love the drift around turn 2 after 🔥🔥🔥
Very impressive!
Great driving! The car seems so stable. And entry is smooth.
Veeeeeeery nice lap time!!!! Sweet drift on Andretti!!
Thanks!
That was a proper lap, well done 👍
these cars are generational great
Awesome!
Great lap
Great lap.
Man, what a lap! I remember when a 100s lap was a good lap time. This was a 91s, amazing!
Thanks! Me too.
Within 0.2s of Randy Pobst in a Ferrari 488 GTB!
You're right! To be fair, that lap was pre-repave. I expect to go faster still given the opportunity (clear track).
Cool video
wow, they made a real life track out of a GT map
Yes, isnt it amazing how games can shape our world?
🔥🔥🔥🔥
Thats some great driving!
Anyone know why in the US you must drive with windows fully down?
For reference, in the UK we have to track with windows fully up and wear long sleeves.
Thanks! We had some good discussion on this elsewhere in the comments. I wish we could run with windows up, and probably should have been wearing long sleeves (but won't go so far as to wear my old racing suit in a road car).
What a nice hud
RaceChrono Pro!
Impressive driving! You get to full throttle, fast, on corner exit! Nicely done.
Porsches, even the Cayman, do power down at corner exit very well :).
@@teddyframhein You're a far better driver than I am! I just did the 2-day Porsche Performance course at Barber Motorsports Park in February and now I'm eager to go back for the Masters course. Would love to have a car of my own to take to our local track. Keep posting as I really enjoy your videos.
That's awesome. Enjoy! Most everything Porsche builds is - in my experience - excellent, so whatever you eventually jump into I'm sure you'll be happy.
I'll continue to post as I make progress with the new car.
Nice
Impressive driving - you're not fooling around 😅
Technically I do this for fun, but I’d be lying if I said I didn’t have goals.
Wow that was awesome, let me go do that on Forza and cry.
Awesome lap. Love to see racechrono pro getting some love. Are you using any external sensors with it?
Yes - a kiwi OBD2 adapter and the RaceBox Mini you can see sitting on the dash.
@@teddyframhein Hi, which OBD2 adapter? Any noticeable lag with it?
I have a kiwi 4. There's slight delay between it and the RaceBox that I haven't bothered trying to account for, and then typically a second or so delay between data and video that I manually adjust before exporting video.
Great job, are you running OEM pads and can you share your camber settings?
OEM rotors and pads for now, and approximately -3 front, -2.5 rear.
@@teddyframhein What do you think of the A052s vs the AD09s? I just ran AD09s on the GT3 but I'm very impressed you can turn those times.
I don’t know much about the AD09’s but I can tell you the A052’s have been the choice at 200 treadwear for autocross for the last few years. Bridgestone’s new RE-71RS is also right there.
These tires are great from cold and much grippier than their treadwear rating would suggest, but do fall off at higher temperatures. So far I’ve done two or three push laps at a time and they seem fine.
Grassroots Motorsports has a great overview of competitive options here: grassrootsmotorsports.com/articles/track-tire-buyers-guide/
Good lord. Sub 1:30 possible, looks like! 😮absolutely nuts
I think so. Lower track temperature, less margin, no mistakes.
Out of curiosity what car did you track before GT4 rs?
Both a 981 Cayman GTS which I also used for autocross, and a stint in a Spec Boxster, both of which have been sold.
@@teddyframhein Thank you for the reply! Helpful to know how to end up in a 718 GT4 RS ;)
Unfortunately/fortunately all you need to end up in a 718 GT4 RS is $$$!
@@teddyframhein hahahahaha TRUE
Any reason why the windows are open? On most European track days the drivers are forced to keep windows closed...
Ha. Here in America we’re required to keep them open… For safety? Sorry about the wind noise!
@@teddyframhein Ha really….for safety? What’s the extra safety idea with windows open? In Europe we need to keep them closed on trackdays…funny there is a different safety idea in each country ;)
@@Franzinoin the US, I believe windows open allows someone to crawl or be pulled out of a wreck car.
What’s the reasoning for windows up in Europe? To mitigate items falling out of the car and onto the track?
@@dabjabar I think that because here in america they don't know blinkers exist and prefer to use hands out of a car to show other driver he can overtake you. You know, safety...left the chat
@@maximborodyuk3773 Realy? On track you use hand signals to pass in US?
100% throttle please 😎
There must have been a banana caught under the pedal.
Alignment specs?
I had BR Racing help set a baseline. Without going into too much detail: slight drop overall, slightly more rake, as much negative camber in front as possible which is potentially limited by rear camber/toe. I started with the front bar at full soft and the rear at full stiff and have since softened the rear for additional traction (note the oversteer at the exit of T5 on this lap - not ideal).
@@teddyframhein Thanks! I am running a 981 GT4 but was just curious as to what the stock 4RS is capable of before getting into things like camber plates, wider tires, etc. I'm running -2.5 f / -2.0 r camber as a 50/50 street and track setup and front castor bushings to correct that issue. At my skill level, that is sufficient for now.
My goal is also the leave the car stock, it's pretty fantastic as-is. We managed -3 f / -2.4 r.
@@teddyframhein That's great. I think many "alignment shops" are not understanding how to adjust the castor using the existing 4RS bushing (which I had to install aftermarket into my std GT4). Anyway, cheers, your video is very informative for a novice driver trying to get better.
160k for this car? 🤦♂️🤦♂️🤦♂️ shifter kart feel so much faster just for 10k. Who tf are making these prices up 🤦♂️
“Who tf are making these prices up?”
Economics
I mean, having tried and failed to fund a push into higher-level racing series, I get it. If the goal is to go racing, sim and karting are better options.
Compared to other road cars though, this thing feels like decent value - everything Porsche can throw at the chassis, plus a true connection to motorsport in the powertrain. It's a genuine step on from my Spec Boxster in terms of pace, and it's road-legal and comfortable enough to relax in (relatively speaking) on the way to and from the track.
