The appealing BMW M3 Sedan is now available with a tuning program developed by Kaege. Most of the works can be found under the hood where the six-cylinder 3.0-liter turbocharged gasoline engine has received a plug & play software solution providing a healthy boost. While the stock engine is capable of pushing out 431 HP (317 kW) and 550 Nm (406 lb-ft), the revised variant develops 517 HP (380 kW) and 700 Nm (516 lb-ft) of torque. The added power is available for €2,799 and is also compatible with the M4 Coupe & Convertible variants.
At an additional cost, the BMW M3 Sedan and the M4 duo can get a KW variant 3 coilover suspension available at €1,999. Kaege is also selling a €2,949 wheel + tire set consisting of 20-inch BBS alloys shod in Michelin Pilot Super Sport tires measuring 255/30 R20 front & 285/30 R20 rear. An adjustment and wheel alignment is an extra €299 while on the inside the cars can get carbon fiber paneling on the backrests for a rather steep €1,499.
