A supercharger helps to increase the GTS's power from the standard 450- to 635hp, while torque rises from 440- to 630Nm. Other additions from G-Power include a lightweight titanium exhaust that lets the engine breath more freely.
The results of G-Power's work is an M3 GTS that can go from 0-100km/h in 4.1 seconds and hit a top speed of 323km/h. Fittingly, G-Power calls the upgrade the SK II Sporty Drive package.
G-Power leaves the suspension and wheels of the limited edition M3 GTS as standard, saying they are already perfectly balanced and race-ready.
