No modifications may be made to the body. As far as trimming is concerned, the body must maintain some vertical surface at front of body (leading edge); suggestion is to cut front of the body at the manufacturer's cut line (if provided), then once mounted and tried on the track, trim only as much as necessary so that it doesn't drag on the track.
