AC Schnitzer’s attempt to set a new benchmark for the BMW M2 at the Sachsenring faced unexpected challenges. Despite carefully tuned power and customized suspension settings, the first run ended in disappointment: the chosen Michelin Cup 2 R tires, borrowed from the Mercedes-AMG GT Black Series, proved too narrow for the extreme speeds on two of the circuit’s key corners. As a result, the rear of the car became unstable, and even fresh adjustments failed to tame the coupe’s handling. In the end, the record was left unbroken, and the AC Schnitzer team did not hide their frustration.
Still, the result of 1:30.60 minutes looked impressive compared to previous years. A decade ago, such a lap would have ranked among the top five out of more than 800 tested cars. But the goal was different—to see the coveted ‘1:29’ on the display. After analyzing their mistakes, the team decided to completely rethink their approach to suspension and tires in order to address the weak points revealed on track.
Technical review
In pursuit of the perfect balance, AC Schnitzer turned to KW specialists and replaced the previous V3 suspension with the racing-spec V4 Clubsport, offering broader adjustment options and external reservoirs. A new set of rear control arms was also installed. Selecting the right tires turned out to be another hurdle: the Michelin Cup 2 R in the required 305/30 R19 size would have demanded major modifications to the bodywork, which was not part of the plan. The focus then shifted to a new solution—the Pirelli P Zero Trofeo RS, recently released in the right size and already tested by BMW on the record-setting M2 CS at the Nürburgring Nordschleife.
The choice fell on 295/30 R20 tires for all four wheels. After mounting them on lightweight forged AC4 wheels 10 inches wide, it turned out that the new tires were almost as wide as the Michelin Cup 2 R 305, but did not require any modifications to the wheel arches. The bodywork remained virtually unchanged, and the car received a new Fire Red color, differing from the former Toronto Red. The engine stayed the same: 560 hp and 650 Nm, with a sports exhaust system and aerodynamic kit featuring Schnitzer brand elements completing the look. To reduce weight, the rear seats were removed and brake cooling was enhanced.
Second chance
On the day of the repeat run, the heat on the track heightened the tension. A warm-up lap on worn Cup 2 R tires showed that the new suspension had completely transformed the M2’s character: the car now handled curbs smoothly, with no more bouncing or excessive oversteer in fast turns. After a short pause and cooling down the car, the team set out for the decisive run in the final minutes before the track closed.
The engine confidently gained revs, and there was not the slightest hint of understeer in the Omega turn. With the new Pirellis, the car responded more precisely to the steering, allowing for earlier acceleration out of corners. The fastest right-hander, Waldmann, could now be taken flat out, and braking became possible much later. Despite the high speed, the driver felt calmer than ever. It was the combination of the new suspension and tires that proved key to success, which was finally reflected on the scoreboard: 1:29.79 minutes — the long-awaited record was set.
Impact on the market
This result placed the AC Schnitzer BMW M2 among the thirty fastest cars on the Sachsenring out of more than 800 contenders. Such success not only strengthened the tuning studio’s reputation, but also highlighted the importance of skilled suspension and tire upgrades to get the most out of production sports cars. According to RUSSPAIN.COM, projects like this are increasingly popular among enthusiasts seeking a balance between factory reliability and personalized settings. Incidentally, interest in modified coupes is also rising alongside new arrivals like the Porsche 911 GT3 S/C, where engineers continue to surprise with unconventional solutions — you can learn more about this in the article on the unique features of the new GT3 S/C.
