A new day and another tuner taking on a BMW vehicle to modify it to their own taste. SKN Groupm, a German tuner who used to work on undercover police cars, takes on the job of modifying the Z4.
Using the BMW sDrive35i model, RNS Z4 RS gains 20,000 euros worth of upgrades. One of them, a power increase above 400 horsepower due to the SKN Power Tuning Stage 3 upgrade.
The engine upgrade takes the Z4 RS from 0 to 60 mph in just 4.1 seconds and the top speed is limited to 295 km/h. The car also features a stainless exhaust system, a new clutch designed by SKN, new upgraded brakes and 19 inch wheels.
Final price with the 20,000 euros upgrades? 59,143 euros, a number that would give us a headache if we converted to U.S. dollars.
