Irsmscher released pictures of a tuning kit they’ve designed for the new Opel Astra GTC.

The sporty GTC has been given an aero kit consisting of a nicely designed front spoiler lip, side skirts, a tall rear spoiler, and a racing rear diffuser which comes with a pair of big tailpipes on each side of it.

The interior is improved with leather upholstery and aluminum accents.

The tuner has also lowered the car’s suspension by 30mm, and bolted 21-inch rims under it. They seem a bit too big for a car of this size. The tires are 245mm wide.

In terms of performance, Irmscher tunes the 180 PS 1.6 liter turbo engine of the car to 220 PS with 274 Nm of torque.

Look out for the car at 2011 IAA.
