Official Hamann BMW Z4 E89 Roadster

Just in time for the start of the cabrio season, Hamann Motorsport introduced a program for the current BMW Z4 Roadster. The options include bodywork styling, rim designs and performance improvements.

The aerodynamics programme replaces the series production front spoiler on the front axle with a version that features two integrated LED day lights. Side skirts are also available. The most striking part of the package is the spoiler mounted on the tailgate. A new rear apron completes the appearance and makes space for the four tailpipes of the Hamann sports exhaust system.

The BMW Z4 sDrive35i engine has been lifted beyond the 250km/h limitation. The performance figures are 360hp (265kW) at 5,230rpm, an improvement of 54hp (40kW). The maximum torque increases to a 540Nm, which is available in the engine speed range of 1,300 to 5,000rpm. Standard is 40Nm at 1,300-5,000. This modification results in a top speed of 285km/h.

A range of wheels include a three-part Hamann light alloy wheel known as the Edition Race “Matt Black”. The 20 inch forged wheel are matt black and polished spoked rims. Hamann is offering the wheel/tyre combination of 8,5Jx20 inch including 235/30ZR20 front tyres with 10,0Jx20 rims plus 295/25ZR20 back tyres. Special chassis springs allow the centre of mass on both the front and back axles of the Z4 Roadster to be lowered by 30 millimetres.

For the interior, the German tuner has come up with subtle internal applications. The aluminium gear knob and the set of foot mats with the silver stitched Hamann logo are of course on the option list. On request, hand-made complete leather fittings in line can also be supplied.
