Front vertical section of the Verus occupy same space as the leading horizontal section of the Hotchkis bar. A no-go combo. (If the Eibach fits with the Verus, the Eibach horizontal section must fit higher, and further away from the rear twist beam.)
My perceived effect of the diffuser suggests an reduction of drag. I first noticed the effect when air-drying the FiST on the same stretch of road (in
Mexico). When lifting near the top of fifth gear, the FiST would normally immediately start slowing... No so with the Verus. I suppose one can do repeated coast-down tests, but I'm not quite as studious as
@Siestarider on his front air-dam experiments.
Also noticed a bit more dust on the back. Not what you wanted
