APP Europe had a few goals when they decided to modify the current BMW M3, which was to create a track day car with reduced weight, better driving dynamics, added engine performance and stable braking. The result is this, the StopTech M3.
Starting off, they played with the M3’s 4.0-litre V8 engine and increased power output to 450 hp from the standard 420 horses with the help of a tuning kit from Collaction AG. This also adds 40 Nm of torque to make 440 Nm. Next was the brake system by StopTech, which comprises forged aluminium and anodized 6-piston calipers with two-piece 380 x 32 mm discs at the front and 4-piston calipers on 355 x 32 mm discs at the back. This set is claimed to be much lighter and more powerful than the stock items.
To improve driving dynamics, APP added a KW Club Sport suspension, a titanium exhaust system and 19-inch ATS ‘Race Light’ wheels covered with Michelin Pilot Sport 2 tyres. The exhaust system is 23 kg lighter than the standard set, while each new wheel is 1.5 kg lighter than the ones supplied by Munich. Instead of matte black, this car’s skin gets a matte titanium silver foil for a metallic effect and clean finish.
