First, watch my first GT4 RS track test
If you haven’t seen my first GT4 RS track test (3:10.76), I’d recommend starting there.

This video builds directly on it. The GT4 RS is still 100% stock—nothing has changed. The first video covers the baseline, setup, and my predictions of where I believed both the car and I would ultimately end up by returning on the same original Cup 2s, and later on Pirelli Trofeo RS. This video is the first test of those predictions.

Why this lap interested me
I returned to Gotland Ring. Same driver. Same car. Same track. Same original factory Cup 2s.
This time I knew the GT4 RS much better. I trusted the braking more and understood the balance better. The original factory Cup 2s, however, had lived a very different life.
Since my first GT4 RS track test, they had completed:
* GT4 RS break-in (1,500 km)
* Porsche Club Norway – 2 track days at Gotland Ring
* Sweden → Nürburgring
* Unlimited-speed Autobahn runs
* ~10 Touristenfahrten laps
* Two Nürburgring track days
* Nürburgring → Sweden
* Normal road driving
* Wet drifting
* Back to Gotland Ring
By the end of this session they had reached approximately 6,400 km.
I only did two push laps. The first was 3:10.34—already quicker than my first GT4 RS track test. After a short cooldown and half a warm-up lap, I went again: 3:09.22.
What interested me most wasn’t simply that the lap improved by 1.54 seconds. What really caught my attention was the telemetry.
During my first GT4 RS track test (3:10.76), Porsche Track Precision recorded 7 ESC / TC interventions.
This time, on the exact same original factory Cup 2s after approximately 6,400 km of break-in, Autobahn runs, Nürburgring laps, track days, road driving, and countless heat cycles, it recorded 39 ESC / TC interventions.
Driving faster naturally asks more from the car. But seeing 39 interventions instead of 7, while improving the lap by only 1.54 seconds, matched exactly what I felt behind the wheel. Most of the lap time came from much more confidence under braking, while the car was moving around considerably more through the corners.
To me, the explanation is straightforward. After everything these original factory Cup 2s had been through, they were far from where they had been during my first GT4 RS track test. Less grip resulted in much more ESC / TC intervention—yet they still delivered a 3:09.22.

Pirelli Trofeo RS. Same driver. Same car. Same track.
Let’s see what changes.
