ATT-TEC, based in Rastatt, Germany, has released optimised and individualised 1 series M coupé featuring new wheels, some technical upgrades and a KW suspension.
The vehicle is fitted with ADV.1 5.0 TF light-alloy wheels of sizes 9×20 inch and 11×20 inch. These three-part wheel rims are individually manufactured for each customer. As an alternative to the stepped lip design shown here, ADV.1 wheels are also available in flat designs. Fitted on the wheels are Michelin Pilot Super Sport High Performance tyres of size 245/30ZR20 up front on the leading axle and size 295/25ZR20 at the back. The price for the complete wheel set shown is EUR €7,760 including VAT.
The Germans also fitted the KW DDC (Dynamic Damping Control) coilover kit with ECU (Electronic Control Unit). At the push of a button, the driver can choose between three car-specific damper settings (Comfort, Sport & Sport+). A Wi-Fi module is also available as an optional extra for the DDC ECU chassis system, enabling custom configuration of the damper set-up via a KW DDC app for the iPhone, iPod touch or iPad, including the ability to swap different set-ups via email. The KW DDC chassis technology system costs €2,799 including VAT. Assembly of the system, including wheel-alignment and set-up is provided by ATT-TEC for €449.
ATT-TEC has upgraded the engine performance of the 1M from stock 336bhp to 395bhp. With the installation of a larger intercooler, the vehicle can even reach up to 454 bhp. Other changes are the Vmax removal and the Evolution Line titanium exhaust system from Akrapovic. It has a wireless flap control system and is optionally available with Titanium or carbon double exhaust pipe ends. The complete Akrapovic Evolution system, including wireless kit, costs €5,934 including VAT. Assembly costs a further EUR €369.
What’s not installed on the vehicle shown here, but due to be available very shortly, is a range of carbon fiber parts for the BMW 1M. Parts scheduled to be available soon include a front spoiler, a rear diffusor, a rear boot lid as well as a range of interior parts.
