APP Europe is offering a series of enhancements designed to make the BMW E92 M3 a more exciting sports car.
The APP BMW E92 M3 comes with upgraded Stoptech STR brakes that are weighting 8 Kg less per axle, 19 inch ATS ‘Racelight’ wheels wrapped in high speed tires (that enable a 6 Kg weight loss), a KW club-sport chassis and a titanium exhaust system which is also 23 kg lighter that n the one on the stock version.
The V8 engine powering the APP BMW E92 M3 received 30 additional horsepower which means it now pushes 450 HP while torque has also raised by 40 Nm.
At the exterior the APP BMW E92 M3 features a Metallic foil and details regarding how much will customers have to pay for this conversion are available upon request.   
APP Europe press release:
APP Europe brings the optics of the M-Boliden with performance on the road. With a specialsporty
tuning program gives APP particularly exciting optics to the current BMW E92 M3.
The sales of the German Stoptech high speed brake equipment offers a firstclass performance vehicle for the ambitiousTrackday pilot.
The goal: Weight savings, driving dynamics, engine performance and stable brakes!However the Stoptech STR highpower  brake saves per axle of the M3 over 8 kg: The Stoptech STR brake equipment is manufactured from forged aluminum, which is front axle provided with anodized 6-piston saddles with two-piece 380x35mm disks – the rear axle with 4-piston and 355×32 disks. (A pointed delay value of -13,4 m/s is reached!!!)
Really many one-piece and multipart wheel designs can be choosen with APP. Here however the light variant of ATS „Racelight “ in 19 inch with Michelin pilot sport 2 high speed tires was selected. This rim combination saves for each wheel in relation to the series 1.5 kg, and this becomes substantially apparent in the driving dynamics.
The chassis can be easily called very sporty now. That makes a KW club-sport chassis possible. In addition you get an Akrapovic titanium evolution system, a titanium exhaust system with sport metal catalysts, which are 23 kg easier than the series.
By the Swiss Stoptech partner, the Collaction AG in Widnau, the power of the M3 V8 was raised by 30 HP to 450 HP. The torque rises around 40 Nm, which also fits much earlier. That makes the power development of the high speed engine clearly more harmonious and increases the fun factor on the racing course!
From the foil specialist and APP partner for many years, CFC (Car film Components), the car with a sensational new foil was pasted. A titanium silver/weak with Metallic effect, that is the optical high point of a project car all around succeeded!
Now the power ratings are clearly in the range of excellent sports cars. The relatively inconspicuous getting ahead prestige will lead with certainty to some consternationof various owners of sports car.
