the build quality is fantastic though! A+ to RB for that.  |
They will work if you can slip a couple of ~1mm thick titanium or aluminum backing plates behind the pads. It wouldn't be difficult to source the titanium backing plates because the pad shape is the same as the rear pads on Mitsu EVOs with Brembo calipers.
They don't recommend using the kit because they can't be sure that everyone will follow the recommendation, and straight out of the box, technically, they don't work. Plus, ideally they'd like to sell you their rear rotor as well for a true performance upgrade.
But I have confirmed. It is possible with backing plates.
