Press Release: Dinan S3-R M3 Revealed. A 527 hp 407 lb-ft +200 mph monster when the pedal is to the firewall and a comfortable daily driver in bumper to bumper.

The M3 name by itself carries a lot of weight in the automotive world, sitting at the top of the 3 Series line as BMWs sportiest offering. An impressive car right out of the box, with details like a carbon fiber roof, powerful brakes and an electronically adjustable suspension that are reserved only for the M badge.

The Dinan S3-R M3 takes the M3 to a whole new level, hiding under the conspicuous hood is 527 horsepower and 407 foot-pounds of torque, up 113 horsepower from the stock engine.

The stock V8 engine is bored and stroked for a gain of 608cc of displacement. The Carbon Fiber High Flow Intake and bored out High Flow Throttle Bodies add more oxygen rich air while the Middle Racing Exhaust and the connected High Flow Exhaust let the spent gasses exit with ease. And the story does not end at the engine like so many of these stories do but continues on to the practical, with suspension upgrades to match the newly found power and the massive amount of rubber now beneath it.

Dinan’s wheel and tire combination put 275/30 tires on the front and 295/30 tires in the rear on a one piece forged wheel that weighs just 19 lbs, significantly reducing unsprung weight. To handle the power and torque delivered to the larger wheels the suspension was upgraded with new springs, front anti-swaybar, Carbon Fiber Front Strut Braces and Racing Rear Toe Links to put the power to the ground. The E92 M3 carries the tag line on the BMWNA website that “racecars shouldn’t be confined to race tracks”, Dinan could not agree more.
