Perrin [15-25 WRX] Shifter Detent Kit | PSP-INR-041RD

Upgrade your gear changes — the PERRIN Shifter Detent Kit delivers sharper, more confident shifts in your WRX or STI.

If your manual transmission feels vague or imprecise, the PERRIN Shifter Detent Kit is the perfect solution. This simple yet effective upgrade replaces the factory detent bolts with custom-engineered PERRIN units that improve shift feedback and reduce play in the gear selector.

Each bolt is precision-machined to tighter tolerances and designed to enhance the mechanical feel of your shifter. The result is a crisper, more direct connection to the transmission — especially noticeable during fast or aggressive driving.

Whether you’re daily driving or carving corners, this inexpensive mod brings a satisfying level of precision to your gear changes.
