Visually, the Alpine White model wears carbon fibre mirror casings, a trunk lid lip and front apron flaps from the BMW Performance program, while the original wheels have made way for a set of powder coated BMW 220M forged rims, which measure 8.5 and 9.5 × 19-inches and come wrapped in 235/35 and 265/30 Michelin Pilot Sport Cup tyres. Moving inside, the BMW Performance seats and steering wheel are trimmed in Alcantara. Swish.
The performance upgrade begins with a stainless steel exhaust system featuring a 100-cell HJS catalyst, an X-pipe with centre silencers and a rear silencer with vacuum-controlled flaps. The sonancy of the system can be controlled by the driver via the car’s M button. The new exhaust releases 20 kW (27 hp) from the naturally aspirated 4.0-litre V8 engine, with a remapped ECU taking total output to 345 kW (470 hp) – up from 309 kW (414 hp).
Chassis enhancements include a Brembo GT braking system which comprises of 380 mm front discs gripped by six-piston calipers and 320 mm discs with four-piston items on the rear. The stainless steel KW DDC ECU coilover set-up can be adjusted via the EDC buttons, through the pre-selection in the M drive menu or even via the free KW DDC iPhone app. Revised ABS software reduces braking distances, while tweaks to the dual-clutch transmission’s electronics minimizes gear change times.
