Looking to differentiate your M3 soft-top from the hoard of 335i convertibles? AC Schnitzer have a styling and dynamic solution for you.The renowned German BMW tuning specialists have given the new M3 convertible a going over and the end result is a rather garish looking state of affairs callled the ACS3 convertible. New chrome grille insets are underscored by a revised front skirt and carbon fibre spoiler. The standard M3 V8 bonnet power dome was obviously going to lend itself to an AC Schnitzer styling interpretation and subsequently sits between two bonnet vents now; which allegedly emit additional acoustic effects whilst driving.Along the flanks flexibly moulded side skirts emphasise the wheel arches – which house rather hideous 20-inch AC Schnitzer mags. Dynamically the ACS3 benefits from AC Schnitzer’s vast Nurburgring experience via new height adjustable suspension featuring Schnitzer springs. Stability is further aided by the new rear-diffuser. For now, bar the sports silencer, the M3 V8 has been left untouched. AC Schnitzer is in the process of developing a performance conversion for the 4-litre V8 engine, though we doubt how much more power they could possibly squeeze from the legendary engine without seriously denting reliability. Expect some mild ECU remapping and perhaps high-flow catalytic converters.
