Dinan Engineering introduce us their BMW 550i in both rear-wheel and all-wheel drive variants package.
The main attraction of this kit is the uprated V8 4.4-liter TwinPower engine which now develops 542 HP and 587 lb-ft of torque, up from the series 400 HP and 450 lb-ft. This was done ny the tuner’s own larger intercoolers and turbochargers, along with a tuned exhaust system, ECU remapping and a carbon fiber high-flow intake.
With all of these modifications, the BMW 550i by Dinan Engineering can hit a top speed of more than 200 mph. Other changes include negative camber front control arms, low compliance rear control arms and bespoke lowering springs. Other options are Dinan’s lightweight forged wheels, Brembo braking system, limited-slip differential, as well as carbon fiber front fascia, mirrors and rear spoiler.
Dinan Engineering offers a 4-year / 50,000-mile warranty for its upgrade kit.
