With a more aggressive front end, lower stance than the previous model and bit more pronounced lines to keep a rigid form under load they aim in improving performance and matching the DBX body.
At the recent ETS Madrid race, it did not seem to be the preferred choice and team drivers reverted in the end to the ZooRacing body, although this may be contributed to other reasons, one of them being the fact that Xray team seemed to be lost with set up in the extreme cold conditons of that particular event. When such issues occur it is common to try and maintain one performance factor unchanged in order to have a consistent reference point. Thus I presume was the reason for choosing DBX for that race.
The future will show whether this body is a top performer or not.
Quality wise, it seems to be a well-designed product, with nice clear and rigid lexan. A lot of attention to detail has gone in the front end to channel air so that it increases downforce. The DBX seems to be a bit nicer in fit and finish as the Racer2 required to be positioned a bit higher than I would have liked in order to meet the 115mm height rule.
Aesthetically I prefer it as the cabin is not as forward as the DBX and it has nicer proportions in my subjective view.
Anyway, here are some photos of the body:
