Puchheim-based performance specialist Tuningwerk has revealed details of its new program to suit BMW’s feisty M135i.
Packing a turbocharged 3.0-litre straight six-cylinder, which churns out a delicious 235 kW (320 hp) in factory guise, Tuningwerk fits its own upgraded turbocharger unit along with an enlarged intercooler, an additional radiator, remapped ECU software and a complete exhaust system with 200-cell catalyst, resulting in 331 Kw (444 hp).
Additional components include a single mass flywheel weighing 4.5 kgs less than the original item, a limited slip differential, a fully adjustable KW Clubsport coilover kit and a set of lightweight 18-inch alloy wheels wrapped in 245/40 and 265/35 Dunlop Direzza semi slick rubber. Behind them the BMW Performance brakes benefit from race-spec pads and stainless steel flexible hoses.
Moving inside the cabin, there’s a pair of Recaro Pole Position racing seats with the company also offering an optional roll-cage for the more serious trackday enthusiasts.
