Even if it`s the most powerful version of the current 4-Series, except the mighty M4, the 435i model received a tuning package that can increase its performances. The authors are Best-Tuning company.
They started working on the 3.0 liter six cylinders petrol unit and managed to tweaked it so it offers 365 hp instead of the stock 306 hp. The simply remapped the software and are charging 1299 euro for this.
To cope with this power, Best-Tuning also installed a KW coilover suspension, that will set clients of 1100 euros. Fortunately, it works very good with the xDrive standard system.
And to change the appearance, best-Tuning also worked with Schmidt revolution on a fresh new set of 20 inch alloy wheels, with 235/30/20 front and 275/25/20 rear tires. Prices for this last upgrade costs 2600 euro.
