The suite of upgrades means an improvement to overall performance. The BMW M3 Saloon and BMW M4 Coupé with optional 7-speed M Double Clutch transmission go from sprint from rest to 62mph in just 4.0 seconds, while the BMW M4 Convertible reaches the same speed in 4.3 seconds. The sprint time for models with the standard 6-speed manual transmission is likewise 0.1 seconds faster in all cases compared to the standard car.
The Competition Package includes Adaptive M Suspension, which has been extensively tuned to the enhanced performance and handling, features new springs, dampers and anti-roll bars, along with reconfigured driving modes (Comfort, Sport and Sport+). The standard Active M Differential on the rear axle and DSC Dynamic Stability Control have likewise been configured to match the upgraded dynamics. Exclusive forged, machine-polished, weight and rigidity optimised 20-inch M alloy wheels with exclusive multi-spoke M styling and mixed tyres (front: 265/30 R20, rear: 285/30 R20) complete the list of chassis upgrades.
For the BMW M3 and BMW M4 Coupé, the Competition Package includes special lightweight M sports seats that combine perfect support under extremely hard driving with exceptional comfort on long journeys. Seatbelts with woven-in BMW M stripes cap off an extremely sporty interior ambience.
Eye-catching exterior highlights of the Competition Package include the M sports exhaust system with black chrome tailpipes. Even more than its good looks, the most distinctive feature of the M sports exhaust system is its potent sound, which brings added emotional resonance to the driving experience. The starting rumble and the distinctive burble on overrun never fail to get under the skin of dedicated drivers time and again.
The Competition Package for the BMW M3 and BMW M4 is topped off by extended BMW Individual high-gloss Shadow Line exterior trim. The high-gloss Black finish has been applied not only to the side window trim, window recess finishers and exterior mirror frames and bases, but also to the BMW kidney grille, the side gills and the model badge on the tail.
Unique M Carbon Compound wheels for the BMW M4 GTS. The new BMW M4 GTS and its six-cylinder in-line engine that develops 500hp with the help of the water injection system employed for the first time, will now be offered with unique BMW M Carbon Compound wheels. This results in a significant reduction in unsprung and rotating masses creating a positive effect on the car's acceleration and deceleration, steering responses and vibration levels.
Designed for the race track yet also approved for road use, this technological showpiece is therefore the world's first series-produced vehicle that can be fitted with wheels boasting a CFRP/aluminium-composite construction. They enable around seven kilograms to be shaved off the weight of a BMW M4 GTS fitted with the already extraordinarily lightweight forged aluminium wheels specified as standard. Rim wells in exposed carbon also lend the BMW M Carbon Compound wheels exclusive visual accents. The wheels are fitted with Michelin Pilot Sport Cup 2 tyres adapted specially for the BMW M4 GTS.
