G-Power has revisited its tuning kit for the BMW M3 GTS which was initially launched back in 2011. They updated the SK II Sporty Drive supercharger kit from the previous 635 HP (467 kW) to the current 650 HP (478 kW) and a maximum torque of 465 lb-ft (630 Nm).
Thanks to the additional horsepower, the BMW M3 GTS is capable of performing the 0-62 mph (0-100 km/h) sprint in 4.1 seconds, making it 0.1 seconds faster than the previous tuned model. It needs 11.8 seconds from 0 to 124 mph (200 km/h), before hitting a maximum speed of 200 mph (323 km/h) which has remained the same as before.
If you are interested in this kit, G-Power says it costs 23,500 euro plus installation charges. You can also order ceramic front/rear brakes (14,460 euros front + 11,778 euros rear), along with 20-inch alloy wheels wrapped around in Michelin tires for 7,437 euros.
