STI-R is much more stealthy than ordinary STi, but how about the rear detection? Is there rear receivers available as an option? I remember I saw something like that once, but not 100% sure.
Then about the placement. Is the detection good enough if placed behind the front grille which is metallic but has pretty big holes in it. Plus the metallic bars are pretty thin. Like in this one:
Even if the metallic mesh won't obstruct RD's "view", will the placement be too low if placed behind the grill? I bet it will, as I've read many times that STi Driver is better to place as high as possible, think it's same thing with remote model.
If the rear receiver is available, I bet it'll be too low if placed under the rear bumper? Like this:
