With the GT4 version of the Porsche Cayman confirmed last week, we thought it would be a while before we'd see the company testing an actual prototype of the car. But now, we have spy shots directly from Germany, featuring the little Porsche's high-performance version. Few details are available, so we'll only tell you what we see: a lower ride height, new aero kit, larger brakes, a big lip spoiler and a massive rear wing. We expect to be talking about this model a lot more before its 2015 reveal.
