Great thanks. Problem is I only got an holder to attach to glas Windows and its now attached as far to front as possibel in the rear window. Need to get an other holder For cage. An other thing is i might need to set new start/finish line due to now I might not make it to startline under 2min. Due to phone in rear then buckle up and enter track from Pit and do a lap, then i reach My start line. Better set new start line wich start instant when I left Pit( this is a must if you place iphone where you can't reach it while driving). If iphone in front of you My set start/finish line work fine.
To some not used to read datatrace it might be hard to understand. But this 2 following pics Will show how easy you see where you gain or lose time in the graf. First i compare slowest lap vs fastest, then fastest vs slowest. Please see the blu coulor graf. Easy to overall compare to see what sections you drive wrong. From here you just press any chosen play button to see lap.
Slover lap vs faster, Compleat lap, see how timediffer (blue area) change vs below pic when i compare faster lap vs slower.
Drove pirellis, still car is Factory setting in camber/toe. My goal was to try that in fast nur and a slow swe track, now I will see what difference a real aggressive setup will do For me. Car stll understeering way to much.
Drove most laps 100% ESC OFF, see fastest 1.30.77 in this comparsion dark Green line show ESC OFF, no trigger points in the line. Slower lap ESC ON, see it trigger the lightgreen line from slower lap. Still the 2 laps understeer plenty, see all downpeak yellow on faster lap and light yellow in slower lap. That is some understeer in a 3km lap. I WILL not suffer like that when car is propper set up in camber etc. I will show data trace from same tracks after set up. Yellow peak up is oversteer, as you see its not an issue, even I get to a few oversteer slides. På is on in swedish , av is OFF

Would think that softening front roll bars one notch would dial out some understeer. That should add some grip up front.
Thanks. But front rollbar is at stoftets setting as well rear rollbar hardest. That I did rather instant at Nurburgring after the first day of driving. It acually got a fraction better then but not that much of a difference. Depending on speed on track and driving style, this car is to understeery. But It will be great when set up I am sure.
I was happy to reach over 200 gps km/h on this short straight with only 385hp GT4. It was not easy, was mostly at 198 gps km/h. Hence i only did it once in this 1.31.03 lap:-)
Just before applying brake, same place at 200 km/h
Then exactly same place as datatrace obove at 201 gps km/h applying brake.
This pic show how I trailbrake long in to turn.
Green is throthle position, red braking pressure, yellow steering angle. See yellow line in graf how i am turning in under braking pressure, in to apex
Same spot
A few meter futher on. Braking way in to apex. See steering angle yellow line and read braking pressure.
Same spot as graf 401m in to track. First turn after straight. Very easy to see the next Guy on Porsche app in Pit as we drive, how he accyally use his car under braking or what ever.
Same lap 401m. Yellow downward peak is heavy understeer 34%. Green show ESC fully OFF in lap. (Av is OFF in swedish) got understeer in how many meters here? Quite some.....
My pirelli tire. This tire did only lap 5-6 laps at nur. And car was on transport home but i acually did drive normal easy and slow street driving ap 2500km and now did one trackday at gotland. Did visit track More than one day but all in all like one day of driving. Tire now looks like this. See front tire.
Inside got plenty of tire left and outer is not that much left really. So it will be nice with some camber.
