Arnas emailed me a link to this build which I know absolutely nothing about, except that it looks damn serious. The link just features a bunch of pictures, so if anyone has any info please feel free to leave a comment.
Edit: Arnas just emailed me some more information on this build. The car was originally tuned to it’s limits using the factory platform until it couldn’t be developed any further. About 10 years or so ago, the Lithuanian owner decided to gut the car completely and build it into the full framed beast you see below, using a composite body and powered by the cars original engine. You can see the car in it’s previous form here.
