The Z4 Coupe is one of the highlights of the sports car segment and, in M guise, delivers a performance that is way beyond criticism. Nevertheless, everything can be made that little bit better. HAMANN took up the challenge and has not only created an aerodynamic kit for the Z4 M Coupй but also boosted the engine output. Additionally, a large range of accessories contributes to greater individuality.

New aerodynamic components

A HAMANN front spoiler gives the Z4 Coupe a more striking look. It gives the car even more sporting lines and comes with ellipsoidal fog lamps. At the same time, it cuts front-end lifting force. For customers who prefer to retain the original bumper, HAMANN can provide mouldings with air inlets. Side skirts lower the Z4 visually and make Chris Bangle's rather austere lines more pleasing to the eye.
Additionally, an air inlet on each side, positioned just ahead of the rear wing, ensures better cooling for the rear brakes. The Laupheim-based tuning company also offers mouldings for the headlight, which round off the visual improvements at the front. To reduce rear-end lifting force, HAMANN fits a striking rear spoiler to the tailgate. The spoiler blends in perfectly with the basic design and emphasises the car's attractive rear end. The roof spoiler also makes an aerodynamic and visual contribution to the Z4 M Coupe by HAMANN. The final optical tweak is the rear diffuser, which HAMANN fits under the rear skirt, whereby cut-outs for the exhaust tailpipes act as counterparts to the apertures in the rear skirt. Thus, the tailpipes are completely surrounded by components, which gives the rear view an additional competition touch.

Anyone who considers the (limited) max. speed of 250 km/h to be insufficient can ask HAMANN to derestrict the engine, which results in a top speed of 273 km/h with the standard engine. Blessed with 343 bhp ex-works, HAMANN tickles a little bit more out of the high-revving engine. Reprogramming the standard engine management system produces an extra 15 bhp (11 kW). Torque rises by 20 Nm. Reprogramming also includes circumvention of the Vmax limit and, after being thus tweaked, the HAMANN Z4 M Coupe reaches 275 km/h.

A great engine needs a great sound. Accordingly, HAMANN offers a 4-tailpipe rear silencer with stainless-steel tailpipes (4 x 76 mm diameter) for the Z4 M Coupe. Even better sound and a more immediate reaction to throttle changes can be achieved by installing a high-performance exhaust manifold and metal sports catalytic converters.

HAMANN provides for even greater agility by fitting progressive suspension springs that lower the ride height by 25 mm. To make the body even stiffer, HAMANN also offers a two-part strut-tower breach (with HAMANN logo), which is fitted at the front.

Two wheel designs in 19 and 20 inches

When it comes to wheels, the HAMANN range has few challengers. In other words, customers have a tempting choice of two aluminium designs and different dimensions for the Z4 M Coupe. HAMANN wheels can also be ordered as complete sets of wheels with tyres.

In the first place, there is the PG3 design. This attractive, multi-part, five-spoke wheel with a silver finish and polished outboard rim flange is available in the dimensions 19 and 20 inches. The wheel / tyre combinations offered:
- 8.5 J x 19 (front), 10 J x 19 (rear) / 235/35 ZR 19, 265/30 ZR 19
- 8.5 J x 20 (front), 10.5 J x 20 (rear) / 235/30ZR 20, 285/25 ZR 20
The single-piece Anniversary I wheel design with a multi-piece look is also available in the dimensions 19 and 20 inches. With its silver finish and highly polished INOX stainless-steel lips, the Anniversary I is also an eye catcher and available in the following combinations:
- 8.5 J x 19 (front), 10 J x 19 (rear) / 235/35 ZR 19, 265/30 ZR 19
- 9 J x 20 (front), 10.5 J x 20 (rear) / 235/30ZR 20, 285/25 ZR 20

A variety of HAMANN accessories and appointments make the interior of the Z4 M Coupe significantly more sporting, e.g., the exclusive HAMANN floor mats with HAMANN logo, a finely wrought aluminium hand-brake grip, competition aluminium pedals, a sports gear-lever knob (two versions: aluminium / leather or 'Racing' aluminium) and a carbon interior set in every conceivable colour, consisting of dashboard mouldings, door-grip mouldings, gear-lever knob and centre consol.
The result: a breath of racing air inside the Z4! Naturally, HAMANN can also modify every Z4 M Coupe in accordance with individual customer requirements, e.g., with luxurious leather appointments in a variety of colours or multi-media conversions.
