yeah, the only 1/8th style bodies that come close are the kyosho dbx, and those red cat 1/10th buggy bodies. I saw a DBX body and it was way too big. If you had the RCM ext chassis, you could probably fit the DBX body.
There's two sides to every schwartz, he got the up side and I got the down side.
I haven't seen the DBX body, but my buddy has a Redcat 10th scale buggy and that body is way too wide for the crt.5. It's closer in width to an 1/8 scale buggy than a 10th truck.
