text size: A- A+
One of these is Tuningwerk. They offer an impressive upgrade on the E89 Z4. The range of options is pretty impressive and includes: reduction of rotating parts weight of more than 50 kg, optimized cooling, CarbonCeramic brakes, exhaust system, light alloy wheels, modified double clutch gearbox and many others.
The most important part is, of course, the engine. An engine upgrade that boosts you N54 bi-turbo engine anywhere from 420 HP o 550 HP and the torque from 630 Nm to 750 Nm. Mind you, the Z4 35is makes 340 HP and 450 Nm in stock form, so that's quite the power boost. Thanks to this amazing increase, the speed limit is being pushed to 340 km/h and the acceleration from 0 to 100 km/h takes half a second less (from 4.2 seconds to 3.7)
That is most impressive, but the best is yet to come. The German tuner, not only brings you the best tuning upgrade for the Z4, but also takes care of you. They offer their clients a driving course in Munich in order to teach them how to handle the new levels of power. That is almost unique in today’s tuning market.
