By the time we got the drop deep enough to produce consistent strafing, we had problems driving in forward and reverse. There just is no right height for a rigid mount.
I had moderate success with a fixed mount h drive in the fall of 2014 albeit the entire chassis was made of folded 1/8" polycarbonate. The flex in the PC acted like a suspension for all the wheels.

All in all I would definitely take a look at 148's robots both their 2010 and 2014 strafe wheel assemblies.
