Many fans of the Bavarian automaker consider the stock BMW M3 (G80) CS hardcore enough to eliminate the need for any modifications. For the rest of us, dÄHLer Competition Line has just released a tuning kit.
The Swiss tuner has managed to massage the stock inline-six engine to 630 PS (621 hp / 463 kW) and 740 Nm (546 lb-ft) of torque. It’s a Stage 1 tune implemented exclusively via software means. You can also opt for a carbon-fiber air intake and a valve-controlled exhaust system, but the latter isn’t recommended because it’s made of stainless steel and not titanium alloy as its OEM counterpart.
Aside from this, there is a nice set of CDC2 21-inch forged wheels coming with spacers for precise fitment. To further enhance the aesthetics, you can ask dÄHLer either for their in-house-designed coilover kit or some normal lowering springs.
The aftermarket company offers the same range of options for the standard M3 sedan and its close sibling, the M4 coupe.
