On the one pictured below, I've got 7mm wheel hexes, slammed the body down using M03 front body mounts on the rear and lopped off 5-10mm from the bottom edge of the shell. Wheels still tuck in perfectly.
Fitting shells can be tricky and frustrating. I've screwed up a few.

See my back wheels are weird. There's lots of room for the wheels but the whee wells didn't line up in the back when the fronts did. I just cut some more out because good chance it breaks anyways and I'm learning still. Might try the Subaru body next. Do body posts bend easily? Wondering if that's my issue maybe?
