I had some shift knobs from an Frs that I wanted on my 22 Brz. If you don’t know, the 22 Brz has a thicker reverse lockout meaning older shiftknobs with old style recess for the reverse lockout won’t fit.
I slapped this billetworkz 22 Brz Reverse lockout adaptor and threw on my Up Garage shift knob. Works like a charm and barely added height to the shifter.
The actual product itself was flawless and well made.
