Senner Tuning targets the limited BMW M2 CS
The 2026 Senner Tuning M2 CS G87 builds on one of BMW M’s most focused compact performance cars. The limited-production M2 CS already represents the sharpest interpretation of the G87 platform, pairing reduced weight with a heavily uprated version of BMW’s twin-turbocharged S58 inline-six.
Yet for tuning specialist Senner Tuning, the CS badge still leaves room for further development. Drawing on more than three decades in the aftermarket performance segment, the company has applied a combination of visual, aerodynamic, and powertrain upgrades aimed at sharpening the coupe’s character even further.
The result is a project car that pushes the already aggressive M2 CS into territory normally occupied by larger and more expensive performance machines.
Exterior modifications and forged wheel setup
The most immediate change comes from the wheel and stance package. Senner fits Wheelforce R.2-FG forged wheels finished in a distinctive light-gold tone.
Up front, the coupe wears 10x21-inch deep-concave wheels, while the rear axle carries 11.5x21-inch ultra-deep-concave variants. Michelin Pilot Sport 4 tires measure 275/25R21 at the front and 305/25R21 at the rear, filling the arches with a purposeful, motorsport-influenced stance.
Suspension upgrades further emphasize the car’s intent. A KW V4 Clubsport coilover system lowers the body and sharpens chassis response, bringing the coupe visually closer to the road while improving handling precision.
Carbon fiber elements also play a visible role. The car features a CS-specific carbon ducktail trunk lid, joined by a Class 3 carbon front spoiler with adjustable splitter and a carbon rear diffuser, both supplied by Alpha-N. Black BMW badges and body-colored rear reflectors complete the understated visual refinements.
The overall effect is not flamboyant, but noticeably more focused.
Carbon intensive engine bay presentation
Opening the hood reveals that the upgrades extend well beyond cosmetic changes.
The BMW M2 CS already produces 530 hp from its 3.0-liter S58 twin-turbo inline-six, delivering 50 hp more than the standard M2.
Senner’s showcase vehicle goes further, introducing the complete carbon component portfolio from Eventuri, including the intake system, engine cover, air scoops, and strut brace. Additional carbon pieces extend to the radiator cover and headlight surrounds.
Visual detailing continues through a Downstar Deluxe Dress-Up hardware kit using titanium bolts and washers, complemented by Goldenwrench Blackline performance caps. The result is an engine bay that appears more like a motorsport display than a conventional production powertrain.
Optional ECU tuning raises output dramatically
For owners seeking more than visual upgrades, Senner offers a deeper mechanical transformation.
An ECU unlock combined with custom engine software increases output dramatically to 710 hp and 865 Nm of torque.
Those figures move the compact M2 CS firmly into the territory of modern supercars. Supporting hardware can include HJS downpipes and valved sports exhaust systems supplied by manufacturers such as Akrapovič, Milltek, Eisenmann, or Grail, alongside a valve control module for adjustable sound characteristics.
The tuning package is optional, but it demonstrates how much performance headroom remains within the S58 engine architecture.
