It took them a while, but AC Schnitzer finally released a preview of their kit for the BMW 1M Coupe ahead of official debut at 2011 IAA.

It is a work in progress though, as there’s no engine upgrade program announced yet. But there is a complete set of new suspension components, new brakes and of course, AC wheels.

For the suspense, the lowering kit drops the car between 10 to 20mm, giving it a cooler look and better stability. It’s completed with AC Schnitzer’s usual wheel collection in different size and designs. The other important upgrade here are the new lightweight ventilated brake discs with 6-piston calipers in the front and 4-piston calipers rear.

At the Frankfurt Motor Show AC will show the complete car, which besides the aforementioned upgrades also benefits from a subtle aerodynamic body kit, revised interior and possibly a heavily modded engine.
